Finish operation 3 of a part

00:02

Finish Operation three of apart.

00:06

In this video we'll use to the adaptive to rough apart well rough and finish A two D.

00:10

Pocket will create drilling and tapping tool paths

00:13

and we'll use bore to finish a whole

00:17

infusion 3 60. Let's carry on with our engine case. Rh ready to program.

00:22

At this point we've created a two D. Adaptive to rough. Our pocket

00:27

has taken down the material to the very top of the boss.

00:29

But we've left 20.2 on the walls and the floor.

00:33

So now we need to go back with the same tool and we need

00:36

to finish the bottom of that pocket before we move on to the rest.

00:41

Because the two D. Adaptive tool path is a roughing tool path.

00:45

We're going to go back using a two D. Pocket tool path.

00:48

Both to the adaptive and pocket are roughing tool paths

00:52

to deep pocket does have a finishing option that allows us to machine both

00:55

the walls and the floor down to our final depth with higher precision.

00:60

So we're going to use two D. Pocket with the same tool.

01:03

Keeping in mind that the tools that we use generally will go in order.

01:07

So we don't have to initiate tool changes often and slow down our program.

01:12

So again, we want to make sure that our cutting feed rate is at 100 inches per minute.

01:16

And the geometry we're going to use is going to be the same geometry.

01:20

We want to select this bottom contour here.

01:22

However,

01:23

we are going to turn on stock contours and we do want to make

01:27

sure that our heights are set to a selection and not to our selected contour

01:32

from here. We're going to move on to our passes.

01:35

Now again, this is also a roughing tool path,

01:38

but we're going to turn off stock to leave.

01:41

We do want to think about if multiple depths are going to

01:44

be needed because we're not roughing out a bunch of material,

01:47

we're only taking a look at the .02 stock that was left on the floors and

01:52

the walls and the tool that we're using has an inch and a half cutting flu.

01:56

We can simply come in and finish the walls and the floor.

01:59

So again,

02:00

we don't really need to worry about coming in

02:03

and roughing or removing large amounts of material.

02:06

We do want to make sure that we enable a finishing pass and notice

02:10

that that opens up a few more options for us on the finishing pass,

02:14

we're going to leave the default .05 step over with one finishing pass.

02:19

Remember we left .02 on the walls and floor. So we're going to do this in a single pass,

02:24

I'm going to say okay, and allow the tool to come in

02:27

so you can see that it's clearing out not only the floor of the material,

02:30

but also the walls, it's moving all the way out to the side.

02:34

Now that we've used our half inch end mill to both rough

02:37

and finish all the way down to the top of this boss.

02:40

Let's go ahead and take a look at the smaller section based on the dimensions.

02:44

We don't have enough room to take a half inch tool in here.

02:47

If you want to verify this,

02:49

you can go to your last operation in this case are two D pocket.

02:53

We can go down to show hide tool,

02:55

we can show the tool and we can use this option to show tool on cursor.

03:00

When we use show tool on cursor,

03:02

we're able to rotate the model around and we can

03:05

see that it does not fit in between the space.

03:08

So this is an extremely helpful thing that we can do

03:10

to verify whether or not we can actually reuse that tool.

03:14

Of course we can measure and we'll know that there

03:16

is less than 3/8 of an inch inside of there.

03:18

So I'm going to go back and I'm going to hide the tool and the holder and

03:22

I'm going to move on to actually go through

03:25

and machinist with the quarter inch end mill.

03:27

So to remove this material in the bottom of the pocket,

03:30

we're once again going to use a two D adaptive clearing operation.

03:34

This time we need to select a new tool that we haven't used yet.

03:37

So in our intro to C and C library, we're going to select the quarter inch flute flat,

03:42

which is tool number five.

03:43

I want to select my aluminum roughing and select the tool When we look at this,

03:49

you can see that the spindle is set to 12,000 rpm.

03:53

The machine that we're using has a limit of about 7500.

03:56

So we need to reduce that and we need to make sure that we reduce it everywhere,

04:00

so 7500 rpm for both the ramp spindle speed and the default spindle speed.

04:06

Then we also need to think about the optimal load for this tool.

04:10

In this case, when we're using the quarter and gen mill,

04:12

the cutting feed rate is coming in at about 100 inches per minute.

04:17

I'm actually going to reduce this a little bit.

04:18

I'm gonna go down to 75" a minute and I'm gonna

04:21

do the same thing for the lead in and the lead out

04:25

notice that there is a higher ramp feed rate and

04:28

I'm going to allow the higher ramp feed rate,

04:30

but in this case I do want to make sure that the plunge feed rate is much smaller.

04:35

Now that we've adjusted those values, let's go to our geometry.

04:39

In this case we want to select the bottom

04:41

face because this is going to automatically detect the

04:44

island or the boss in the center and it's

04:46

only going to be machining this outside section.

04:48

So now that we have this selected,

04:50

we can also turn on stock contours if we want to

04:53

make sure that we do extend outside of that pocket,

04:57

let's go ahead and move this back into view.

04:59

When we turn off stock contours, you can see that it starts right here,

05:02

but we turn it on, it's going to allow the tool to enter from the outside.

05:07

Next we can't turn on rest machining.

05:09

However,

05:10

we're going to be using our heights to dictate where this is going to start and end.

05:14

So in the heights section, the top height is not going to be the stock top.

05:19

In this case,

05:20

what I want to do is use my selection and I

05:22

wanted to start cutting around the top of the boss.

05:26

Now if you are just starting out,

05:28

this is something you need to be very careful with because if you start programming

05:32

and adjusting your top heights to be below your actual top of your part,

05:36

you need to be very sure that the tool is

05:39

not going to make rapid movements and go through stock.

05:42

So we need to be very careful when we verify these tool paths

05:45

that it is staying within the confines of that area.

05:48

Now that we have this set, let's move on to our past section for roughing this cavity.

05:54

I want to take a look at this optimal load.

05:56

Now it's about 0.47 and I'm going to increase that 2.5 for this tool.

06:01

And when we take a look at the stock to leave 0.2 on both the wall on the floor,

06:06

that's going to be just fine.

06:08

I'm going to say okay and allow it to generate this. Notice that the tool is entering

06:14

and it's making that adaptive tool motion to clear everything out.

06:17

One other thing that we could do is we could dictate where

06:21

the tool is entering and this happens on the last tap.

06:24

So if we go back and edit this tool path and we go to our linking parameters,

06:28

we can use a pre drill position

06:30

to have the tool come into the part from the outside or from the center of a hole.

06:35

If we select entry positions and we select for

06:38

example a point on this wall and say okay,

06:41

it's going to automatically force the position where the tool is entering.

06:45

You'll notice that it recalculated our tool path and now the

06:48

tool is entering and exiting generally where we put it.

06:51

Now the exit happens based on where the tool path is finished.

06:55

But in some cases we can force the issue to dictate where it's going to start.

06:60

So in this case we now have adaptive lee cleared that bottom pocket.

07:04

But we left 0.2 on both the walls on the boss the outside and 0.2 on the floor.

07:10

So we're going to come back with a two D.

07:12

Pocket just like we did before using the same quarter inch

07:16

tool as well as the same rpm and feed rate.

07:19

And for our geometry, we want to make sure that we do select that same area.

07:23

I do want to note that there are options

07:25

for pocket recognition inside of these two D operations.

07:29

But when we're just getting started, understanding our selection,

07:32

whether it's a face or if we're selecting individual contours is

07:36

an important step in the process to understand where we're machining.

07:39

But I do want to mention that there are more advanced options that we can use.

07:43

In this case,

07:44

I am going to turn on the stock contours and again you can see that it does extend

07:49

this,

07:50

make sure that our tool is taking into account all the material

07:53

that may be left behind because we did adaptive lee clear everything.

07:57

The stock contour is not really going to add much for us in this case.

08:01

So I will be turning it off for this finishing step

08:04

For our heights.

08:06

We also have to think about where this tool path is starting for the last one.

08:10

When we did our adaptive clear, we started from the top of the boss.

08:14

If we happen to use the feed height as the top height plus .02,

08:19

that means the tool is going to feed all the way from this point,

08:22

all the way down at its reduced feed rate.

08:24

If we go back to our tool selection, you can see that it's leading in at 75" a minute.

08:31

So we do want to make sure that we adjust our heights.

08:33

But again, this is something we need to be extremely careful with.

08:37

We want to make sure that we are understanding where the tool is going to be

08:41

next in our passes. We do want to enable finish passes and disable stock to leave.

08:46

We want to think about the maximum step over 0.0 to five and we want

08:52

to think about our finished feed rate when we're looking at our step over value,

08:57

we should remember that there are actually two different step over values.

09:01

This 20.0 to 5 is for our finishing pass and there's

09:04

a maximum step over that's listed down here as 50.15.

09:08

This maximum step over here is going to account for the major movements of

09:13

the tool and the .025 will be used for our final finishing pass.

09:18

So I'm going to say okay, and allow it to generate this.

09:21

And again that it does know that it's starting from

09:24

outside because it does know that it's an open pocket.

09:27

So it's starting the tool path, entering and exiting from the outside,

09:31

moving its way in

09:32

finishing the floor as well as the outside and inside edges.

09:36

Now that we have these taken care of,

09:38

we can move on to taking care of all of the holes in the part.

09:42

There is going to be a specific order that we should think about this

09:46

and that's because we do need to do a couple of extra operations here.

09:50

We need to do some spot drilling as well as

09:53

some pre drilling and boring in the center here.

09:56

So let's get started and run quickly through

09:58

creating some drilling operations for the drilling operations.

10:02

Again.

10:03

We want to make sure that we are using our

10:05

spot drill and we're going to select tool number two,

10:08

which is our quarter inch spot drill.

10:11

We're going to select our positions and we're

10:13

going to start with the three large holes.

10:16

We need to use these because we don't want to

10:18

pre drill the same depth for the small holes.

10:21

So we're going to start by doing these.

10:22

And in the heights section we're going to use to champ for width.

10:26

It's not going to be able to account for that in the large hole,

10:29

but it will take these other passing holes down and we can say, okay,

10:34

since we have this tool active,

10:36

we're going to repeat the process creating drilling.

10:38

We're going to now select these holes here.

10:41

So I'm going to select these holes

10:45

and note that we want to use auto merge segments.

10:48

It's going to take up the champ for on top.

10:50

And then for the heights we want to use to champ for

10:53

width that's going to automatically account for the champ for for us,

10:56

we're going to leave all the rest of the settings the same and say, okay

11:01

Now we can create a drilling operation for the drilling operation.

11:04

We're going to use intro to C&C. And drill f. This is going to be a .257.

11:11

This drill bit is going to be used for this hole here.

11:15

This large center hole as well as this one.

11:18

We want to make sure that this goes all the way to the whole bottom and we're going

11:21

to allow the drill tip to go through bottom

11:23

just to ensure that we go all the way through

11:26

for this cycle. We're going to set this to chip breaking and we'll say, okay,

11:31

Next, what we're going to do is we're going to drill the smaller hole.

11:34

So once again, we're going to create a drilling operation.

11:37

But this time we're going to be using our .1-5 drill.

11:41

This is going to be a smaller drill bit tool number eight.

11:46

Next we're going to select our holes.

11:49

We're going to allow it to go all the way to the bottom.

11:51

But we are going to use the drill tip through bottom.

11:53

We talked about this earlier on the print because it's a flat bottom hole.

11:57

We either need to take a small end mill in there to finish

11:59

the flat bottom or we can drill the hole a little bit deeper,

12:03

assuming it's allowed based on the print.

12:05

Even though this is not a very deep hole,

12:07

I am still going to use the partial retract chip

12:10

breaking cycle just because it's a fairly small drill bit.

12:14

Next I am going to go ahead and create a bore in the center of this whole.

12:19

Now keep in mind that there are different order of

12:21

operations that we could take instead of using our spot drill

12:25

to take care of this chant for we could come back

12:27

and take care of it using our champ for mill.

12:29

We could also have chance for this whole before but

12:33

we're going to again just pick our order of operations,

12:35

noting that we can always move these things around later.

12:38

But now that we have this hole pre drilled,

12:41

what we want to do is we want to come back with a two D operation called bore.

12:46

We're going to select our quarter inch flat which is tool number five,

12:49

making sure that we are still fixed at spindle speed of

12:56

we're going to make sure that we are going all the way through the bottom of the hole.

13:00

So I'm going to add a small amount to the bottom of minus 0.5.

13:05

Remember when you're using the offset values,

13:07

it's going to be negative based on the Z orientation of our coordinate system.

13:12

When we have passes.

13:13

Note that we do have multiple passes and finished passes,

13:17

I do want to turn on a finishing pass

13:19

and I'm going to have it be a fairly small amount of .025 which is the default value.

13:24

We can also use multiple passes.

13:26

I'm going to do some roughing passes at .125 and I also

13:30

want to make sure that we are using a pre drill location.

13:34

So when we look at these various options, note that inside of here,

13:39

we've got all the various ramp angles, we've got multiple passes,

13:43

we've got finishing passes and so on.

13:45

But when we go to our geometry notice that inside of our

13:49

geometry we don't have the selected option for using a pre drill.

13:53

When we go to our first option here,

13:56

we're selecting the tool and setting the parameters.

13:59

So depending on the order of operations you might not have a pre drill

14:04

or an entry position but when we're using circular tool paths like boar,

14:08

we can always use the lead to center option.

14:11

Now as we turn this on and off,

14:13

you can see all these yellow lead movements move directly to the center.

14:17

So if you are using a board tool path and you have pre drilled it,

14:20

it is important that we think about these options and we do move the tool to the center

14:26

now that we've machined essentially everything,

14:29

we can go back using R two D champ for.

14:31

We can select an appropriate chant for tool and

14:34

again we're going to select tool number three,

14:37

this is going to be our quarter inch champ for mill

14:40

and then we're going to move on to our geometry.

14:43

We want to chant for the entire outside and we also want to come

14:46

back in and take care of these holes when we're using the champ formal,

14:50

these values are going to be set based on the champ for width,

14:53

the tip offset and the chance for clearance.

14:56

So we're going to use 0.1 for the champ for width,

14:59

point oh five for the tip offset and 50.1 for the tip clearance will say okay,

15:06

allow it to deeper all those.

15:08

And now we've finished off op three.

15:11

Do note that we do have a warning on the board tool path.

15:14

It tells us that some passes were disregarded,

15:17

reduce the tool size or decrease the step over amount.

15:20

It's a good idea for us to double check these warnings and

15:23

make any adjustments needed because we're not removing that much material,

15:27

we can go back to our passes and do just a single roughing step over,

15:31

allow it to regenerate the tool path and we can see now we no longer have the warning

15:36

essentially we had an extra path that wasn't producing any tool path cuts

15:41

Now that we have this let's go back to our op three view and

15:45

let's make sure that we save this before we move on to the next step

Video transcript

00:02

Finish Operation three of apart.

00:06

In this video we'll use to the adaptive to rough apart well rough and finish A two D.

00:10

Pocket will create drilling and tapping tool paths

00:13

and we'll use bore to finish a whole

00:17

infusion 3 60. Let's carry on with our engine case. Rh ready to program.

00:22

At this point we've created a two D. Adaptive to rough. Our pocket

00:27

has taken down the material to the very top of the boss.

00:29

But we've left 20.2 on the walls and the floor.

00:33

So now we need to go back with the same tool and we need

00:36

to finish the bottom of that pocket before we move on to the rest.

00:41

Because the two D. Adaptive tool path is a roughing tool path.

00:45

We're going to go back using a two D. Pocket tool path.

00:48

Both to the adaptive and pocket are roughing tool paths

00:52

to deep pocket does have a finishing option that allows us to machine both

00:55

the walls and the floor down to our final depth with higher precision.

00:60

So we're going to use two D. Pocket with the same tool.

01:03

Keeping in mind that the tools that we use generally will go in order.

01:07

So we don't have to initiate tool changes often and slow down our program.

01:12

So again, we want to make sure that our cutting feed rate is at 100 inches per minute.

01:16

And the geometry we're going to use is going to be the same geometry.

01:20

We want to select this bottom contour here.

01:22

However,

01:23

we are going to turn on stock contours and we do want to make

01:27

sure that our heights are set to a selection and not to our selected contour

01:32

from here. We're going to move on to our passes.

01:35

Now again, this is also a roughing tool path,

01:38

but we're going to turn off stock to leave.

01:41

We do want to think about if multiple depths are going to

01:44

be needed because we're not roughing out a bunch of material,

01:47

we're only taking a look at the .02 stock that was left on the floors and

01:52

the walls and the tool that we're using has an inch and a half cutting flu.

01:56

We can simply come in and finish the walls and the floor.

01:59

So again,

02:00

we don't really need to worry about coming in

02:03

and roughing or removing large amounts of material.

02:06

We do want to make sure that we enable a finishing pass and notice

02:10

that that opens up a few more options for us on the finishing pass,

02:14

we're going to leave the default .05 step over with one finishing pass.

02:19

Remember we left .02 on the walls and floor. So we're going to do this in a single pass,

02:24

I'm going to say okay, and allow the tool to come in

02:27

so you can see that it's clearing out not only the floor of the material,

02:30

but also the walls, it's moving all the way out to the side.

02:34

Now that we've used our half inch end mill to both rough

02:37

and finish all the way down to the top of this boss.

02:40

Let's go ahead and take a look at the smaller section based on the dimensions.

02:44

We don't have enough room to take a half inch tool in here.

02:47

If you want to verify this,

02:49

you can go to your last operation in this case are two D pocket.

02:53

We can go down to show hide tool,

02:55

we can show the tool and we can use this option to show tool on cursor.

03:00

When we use show tool on cursor,

03:02

we're able to rotate the model around and we can

03:05

see that it does not fit in between the space.

03:08

So this is an extremely helpful thing that we can do

03:10

to verify whether or not we can actually reuse that tool.

03:14

Of course we can measure and we'll know that there

03:16

is less than 3/8 of an inch inside of there.

03:18

So I'm going to go back and I'm going to hide the tool and the holder and

03:22

I'm going to move on to actually go through

03:25

and machinist with the quarter inch end mill.

03:27

So to remove this material in the bottom of the pocket,

03:30

we're once again going to use a two D adaptive clearing operation.

03:34

This time we need to select a new tool that we haven't used yet.

03:37

So in our intro to C and C library, we're going to select the quarter inch flute flat,

03:42

which is tool number five.

03:43

I want to select my aluminum roughing and select the tool When we look at this,

03:49

you can see that the spindle is set to 12,000 rpm.

03:53

The machine that we're using has a limit of about 7500.

03:56

So we need to reduce that and we need to make sure that we reduce it everywhere,

04:00

so 7500 rpm for both the ramp spindle speed and the default spindle speed.

04:06

Then we also need to think about the optimal load for this tool.

04:10

In this case, when we're using the quarter and gen mill,

04:12

the cutting feed rate is coming in at about 100 inches per minute.

04:17

I'm actually going to reduce this a little bit.

04:18

I'm gonna go down to 75" a minute and I'm gonna

04:21

do the same thing for the lead in and the lead out

04:25

notice that there is a higher ramp feed rate and

04:28

I'm going to allow the higher ramp feed rate,

04:30

but in this case I do want to make sure that the plunge feed rate is much smaller.

04:35

Now that we've adjusted those values, let's go to our geometry.

04:39

In this case we want to select the bottom

04:41

face because this is going to automatically detect the

04:44

island or the boss in the center and it's

04:46

only going to be machining this outside section.

04:48

So now that we have this selected,

04:50

we can also turn on stock contours if we want to

04:53

make sure that we do extend outside of that pocket,

04:57

let's go ahead and move this back into view.

04:59

When we turn off stock contours, you can see that it starts right here,

05:02

but we turn it on, it's going to allow the tool to enter from the outside.

05:07

Next we can't turn on rest machining.

05:09

However,

05:10

we're going to be using our heights to dictate where this is going to start and end.

05:14

So in the heights section, the top height is not going to be the stock top.

05:19

In this case,

05:20

what I want to do is use my selection and I

05:22

wanted to start cutting around the top of the boss.

05:26

Now if you are just starting out,

05:28

this is something you need to be very careful with because if you start programming

05:32

and adjusting your top heights to be below your actual top of your part,

05:36

you need to be very sure that the tool is

05:39

not going to make rapid movements and go through stock.

05:42

So we need to be very careful when we verify these tool paths

05:45

that it is staying within the confines of that area.

05:48

Now that we have this set, let's move on to our past section for roughing this cavity.

05:54

I want to take a look at this optimal load.

05:56

Now it's about 0.47 and I'm going to increase that 2.5 for this tool.

06:01

And when we take a look at the stock to leave 0.2 on both the wall on the floor,

06:06

that's going to be just fine.

06:08

I'm going to say okay and allow it to generate this. Notice that the tool is entering

06:14

and it's making that adaptive tool motion to clear everything out.

06:17

One other thing that we could do is we could dictate where

06:21

the tool is entering and this happens on the last tap.

06:24

So if we go back and edit this tool path and we go to our linking parameters,

06:28

we can use a pre drill position

06:30

to have the tool come into the part from the outside or from the center of a hole.

06:35

If we select entry positions and we select for

06:38

example a point on this wall and say okay,

06:41

it's going to automatically force the position where the tool is entering.

06:45

You'll notice that it recalculated our tool path and now the

06:48

tool is entering and exiting generally where we put it.

06:51

Now the exit happens based on where the tool path is finished.

06:55

But in some cases we can force the issue to dictate where it's going to start.

06:60

So in this case we now have adaptive lee cleared that bottom pocket.

07:04

But we left 0.2 on both the walls on the boss the outside and 0.2 on the floor.

07:10

So we're going to come back with a two D.

07:12

Pocket just like we did before using the same quarter inch

07:16

tool as well as the same rpm and feed rate.

07:19

And for our geometry, we want to make sure that we do select that same area.

07:23

I do want to note that there are options

07:25

for pocket recognition inside of these two D operations.

07:29

But when we're just getting started, understanding our selection,

07:32

whether it's a face or if we're selecting individual contours is

07:36

an important step in the process to understand where we're machining.

07:39

But I do want to mention that there are more advanced options that we can use.

07:43

In this case,

07:44

I am going to turn on the stock contours and again you can see that it does extend

07:49

this,

07:50

make sure that our tool is taking into account all the material

07:53

that may be left behind because we did adaptive lee clear everything.

07:57

The stock contour is not really going to add much for us in this case.

08:01

So I will be turning it off for this finishing step

08:04

For our heights.

08:06

We also have to think about where this tool path is starting for the last one.

08:10

When we did our adaptive clear, we started from the top of the boss.

08:14

If we happen to use the feed height as the top height plus .02,

08:19

that means the tool is going to feed all the way from this point,

08:22

all the way down at its reduced feed rate.

08:24

If we go back to our tool selection, you can see that it's leading in at 75" a minute.

08:31

So we do want to make sure that we adjust our heights.

08:33

But again, this is something we need to be extremely careful with.

08:37

We want to make sure that we are understanding where the tool is going to be

08:41

next in our passes. We do want to enable finish passes and disable stock to leave.

08:46

We want to think about the maximum step over 0.0 to five and we want

08:52

to think about our finished feed rate when we're looking at our step over value,

08:57

we should remember that there are actually two different step over values.

09:01

This 20.0 to 5 is for our finishing pass and there's

09:04

a maximum step over that's listed down here as 50.15.

09:08

This maximum step over here is going to account for the major movements of

09:13

the tool and the .025 will be used for our final finishing pass.

09:18

So I'm going to say okay, and allow it to generate this.

09:21

And again that it does know that it's starting from

09:24

outside because it does know that it's an open pocket.

09:27

So it's starting the tool path, entering and exiting from the outside,

09:31

moving its way in

09:32

finishing the floor as well as the outside and inside edges.

09:36

Now that we have these taken care of,

09:38

we can move on to taking care of all of the holes in the part.

09:42

There is going to be a specific order that we should think about this

09:46

and that's because we do need to do a couple of extra operations here.

09:50

We need to do some spot drilling as well as

09:53

some pre drilling and boring in the center here.

09:56

So let's get started and run quickly through

09:58

creating some drilling operations for the drilling operations.

10:02

Again.

10:03

We want to make sure that we are using our

10:05

spot drill and we're going to select tool number two,

10:08

which is our quarter inch spot drill.

10:11

We're going to select our positions and we're

10:13

going to start with the three large holes.

10:16

We need to use these because we don't want to

10:18

pre drill the same depth for the small holes.

10:21

So we're going to start by doing these.

10:22

And in the heights section we're going to use to champ for width.

10:26

It's not going to be able to account for that in the large hole,

10:29

but it will take these other passing holes down and we can say, okay,

10:34

since we have this tool active,

10:36

we're going to repeat the process creating drilling.

10:38

We're going to now select these holes here.

10:41

So I'm going to select these holes

10:45

and note that we want to use auto merge segments.

10:48

It's going to take up the champ for on top.

10:50

And then for the heights we want to use to champ for

10:53

width that's going to automatically account for the champ for for us,

10:56

we're going to leave all the rest of the settings the same and say, okay

11:01

Now we can create a drilling operation for the drilling operation.

11:04

We're going to use intro to C&C. And drill f. This is going to be a .257.

11:11

This drill bit is going to be used for this hole here.

11:15

This large center hole as well as this one.

11:18

We want to make sure that this goes all the way to the whole bottom and we're going

11:21

to allow the drill tip to go through bottom

11:23

just to ensure that we go all the way through

11:26

for this cycle. We're going to set this to chip breaking and we'll say, okay,

11:31

Next, what we're going to do is we're going to drill the smaller hole.

11:34

So once again, we're going to create a drilling operation.

11:37

But this time we're going to be using our .1-5 drill.

11:41

This is going to be a smaller drill bit tool number eight.

11:46

Next we're going to select our holes.

11:49

We're going to allow it to go all the way to the bottom.

11:51

But we are going to use the drill tip through bottom.

11:53

We talked about this earlier on the print because it's a flat bottom hole.

11:57

We either need to take a small end mill in there to finish

11:59

the flat bottom or we can drill the hole a little bit deeper,

12:03

assuming it's allowed based on the print.

12:05

Even though this is not a very deep hole,

12:07

I am still going to use the partial retract chip

12:10

breaking cycle just because it's a fairly small drill bit.

12:14

Next I am going to go ahead and create a bore in the center of this whole.

12:19

Now keep in mind that there are different order of

12:21

operations that we could take instead of using our spot drill

12:25

to take care of this chant for we could come back

12:27

and take care of it using our champ for mill.

12:29

We could also have chance for this whole before but

12:33

we're going to again just pick our order of operations,

12:35

noting that we can always move these things around later.

12:38

But now that we have this hole pre drilled,

12:41

what we want to do is we want to come back with a two D operation called bore.

12:46

We're going to select our quarter inch flat which is tool number five,

12:49

making sure that we are still fixed at spindle speed of

12:56

we're going to make sure that we are going all the way through the bottom of the hole.

13:00

So I'm going to add a small amount to the bottom of minus 0.5.

13:05

Remember when you're using the offset values,

13:07

it's going to be negative based on the Z orientation of our coordinate system.

13:12

When we have passes.

13:13

Note that we do have multiple passes and finished passes,

13:17

I do want to turn on a finishing pass

13:19

and I'm going to have it be a fairly small amount of .025 which is the default value.

13:24

We can also use multiple passes.

13:26

I'm going to do some roughing passes at .125 and I also

13:30

want to make sure that we are using a pre drill location.

13:34

So when we look at these various options, note that inside of here,

13:39

we've got all the various ramp angles, we've got multiple passes,

13:43

we've got finishing passes and so on.

13:45

But when we go to our geometry notice that inside of our

13:49

geometry we don't have the selected option for using a pre drill.

13:53

When we go to our first option here,

13:56

we're selecting the tool and setting the parameters.

13:59

So depending on the order of operations you might not have a pre drill

14:04

or an entry position but when we're using circular tool paths like boar,

14:08

we can always use the lead to center option.

14:11

Now as we turn this on and off,

14:13

you can see all these yellow lead movements move directly to the center.

14:17

So if you are using a board tool path and you have pre drilled it,

14:20

it is important that we think about these options and we do move the tool to the center

14:26

now that we've machined essentially everything,

14:29

we can go back using R two D champ for.

14:31

We can select an appropriate chant for tool and

14:34

again we're going to select tool number three,

14:37

this is going to be our quarter inch champ for mill

14:40

and then we're going to move on to our geometry.

14:43

We want to chant for the entire outside and we also want to come

14:46

back in and take care of these holes when we're using the champ formal,

14:50

these values are going to be set based on the champ for width,

14:53

the tip offset and the chance for clearance.

14:56

So we're going to use 0.1 for the champ for width,

14:59

point oh five for the tip offset and 50.1 for the tip clearance will say okay,

15:06

allow it to deeper all those.

15:08

And now we've finished off op three.

15:11

Do note that we do have a warning on the board tool path.

15:14

It tells us that some passes were disregarded,

15:17

reduce the tool size or decrease the step over amount.

15:20

It's a good idea for us to double check these warnings and

15:23

make any adjustments needed because we're not removing that much material,

15:27

we can go back to our passes and do just a single roughing step over,

15:31

allow it to regenerate the tool path and we can see now we no longer have the warning

15:36

essentially we had an extra path that wasn't producing any tool path cuts

15:41

Now that we have this let's go back to our op three view and

15:45

let's make sure that we save this before we move on to the next step
