Set up and run OP2

00:00

Set up and run

00:02

up two.

00:02

After completing this video, you will be able to

00:06

install soft jaws into a vice,

00:08

locate a coordinate system on those soft jaws run operation. Two of a part,

00:14

we used hard jaws for our first operation with parallels to support our part.

00:20

Now hard jaws are steel jaws with precision ground

00:24

surfaces that are not meant to be machined into.

00:27

For our second operation.

00:28

We will be using soft jaws

00:31

which are just aluminum or steel jaws that are meant to be machined into.

00:36

These are perfect for holding odd shaped parts during our secondary operations,

00:42

the vice goes on just like we showed you earlier.

00:45

But after everything is straight and tight,

00:47

we will remove our hard jaws and replace them with our soft jaws.

00:57

We will snug the jaws and then set them

00:60

with a dead blow hammer before tightening things completely.

01:03

Now, if we were installing soft jaws that had already been cut,

01:07

we would lightly snug everything, tap things down

01:10

and then clamp on a part,

01:12

clamping on a part before tightening the jaws completely will help align

01:18

that front and back jaws for us.

01:20

We chose to set our W CS work coordinate system

01:24

at the front left corner of our fixed jaw infusion.

01:28

So we need to set our machine work zero at that same spot.

01:33

We'll use the heimer to set our work offset.

01:36

If your machine is a probing system, that's what you'll be using.

01:39

We jog

01:40

our heer to read zero along the X axis, the left edge of our jaw

01:45

and then press the part zero set key with our G 54 work offset highlighted.

01:50

Now, we used W CS one in Fusion 360 which is G 54 which is why we're gonna use

01:58

G 54 work

01:60

offset for this single vice set up.

02:03

We could have added a second vice on the table

02:12

and G 55 for the second operation W CS two.

02:15

That's a good way of doing things,

02:17

but it's a lot more complicated. A lot more advanced.

02:20

We're gonna hit this part using only G 54 W CS one.

02:25

And in future parts, we'll show you that secondary set up and how to use those offsets

02:30

and how to separate things out. But again, for now,

02:32

we're sticking with wcs one.

02:35

OK?

02:35

We'll repeat the process for our Y axis,

02:38

making sure our G 54 Z work offset is set to zero

02:43

and then touch off both of the tools listed on our set up sheet

02:46

right on top of our back job.

02:50

And remember the reason that our G 54 Z value is set to zero

02:56

is that, that Z value

02:58

is simply the distance between where we touch off our tools

03:01

and where our work coordinate system is

03:03

because our work coordinate system is set at the top of our jaws.

03:07

And that is where we touch off our tools.

03:10

There's zero distance between those two

03:12

where we touch off our tools and where W CS is.

03:15

So our G 54 Z zero is

03:18

zero.

03:20

This is the same process we use for

03:22

one, except in our first operation. Our Z zero was right on top of our raw stock.

03:28

And that's where we set our tools

03:29

for this second operation. We've chosen to set our Z zero on top of our jaws.

03:36

This spot makes sense for this op when machining our soft jaws,

03:39

it's our only available feature.

03:41

It also highlights a different way that we can approach our work offsets.

03:45

When programming parts,

03:48

our tool and work offsets are all set and we're about ready to run the part.

03:51

But first, we're gonna show you another method that we can use

03:55

to verify that everything we've done to this point was done correctly.

03:59

Now, this might be

04:01

the most useful bit of G code that you will ever hear.

04:05

You'll wanna take this, write it down on a post it, note,

04:07

stick it in your pocket and save it for later here.

04:10

We go MD I

04:11

M six T two

04:14

G 54 G zero, G 90 X zero, Y zero, G 43 H two, Z 0.1 M 30. The M six T two is pretty simple.

04:25

Uh M six means do a tool change, T two says do a tool change to tool two.

04:31

Now we chose tool two in this case, because it's a pointy tool.

04:36

You'll see why in a moment. T two is our champ for two

04:39

M six T two.

04:41

We're in MD mode will go ahead and reduce our rapids to 25%.

04:46

Put the machine in single block mode

04:49

and run through this code.

04:51

So at this point, we can press cycle start

05:00

and sure enough, the machine did a tool change,

05:03

putting tool to our champ for tool into the spindle.

05:06

If we were to press the cycle start button again.

05:08

G 54 G zero, G 90 X zero, Y zero,

05:12

G 54 is our W CS one coordinate system which is right there on the corner of our jaw.

05:19

So we're gonna command it to G 00, which means go really fast to X zero, Y zero,

05:25

which is zero distance to the X zero distance in the Y

05:29

from our zero point, which is the corner of that job.

05:31

We want that tool to go right above our corner and verify

05:35

that we've said it correctly.

05:37

Uh G 90 we're not gonna talk about much. Uh

05:40

but again, it says just use a Cartesian coordinate system

05:43

that matches everything that we've used in school.

05:46

Uh Xy and Z and all of our commanded XYZ moves will be from that zero point.

05:52

That's what G 90 moves.

05:54

Don't think about it too much just yet.

05:56

Cycle start

05:59

and our machine moved so far, things look good.

06:02

But our tool is still well above our part.

06:05

We need it closer.

06:06

G 43 H two, Z 0.1

06:10

the G 43 H two simply means use offset two. Now, most of the time, almost all the time,

06:17

we use an offset number

06:19

that matches our T number, our tool number.

06:22

Uh That's just the way things work.

06:24

There are certain circumstances when you wanna use

06:27

tool 108 but offset eight,

06:30

we're not talking about that.

06:31

Uh We almost always use an offset number that matches our T number.

06:36

That's why we're using H two because it matches T two

06:39

G 43 just says use

06:41

offset H two

06:43

and go to

06:45

Z 0.1. Now, this is where scary things happen.

06:48

It's these Z moves that we need to verify.

06:51

Now, I've got my rapid set to 25%. I'm gonna press cycle start

06:55

and watch this tool come in.

06:58

That's fast.

06:60

I'm gonna stop it with the feed hold,

07:02

move from 25% rapid to 5% rapid

07:07

and let things come in.

07:11

Now, I stopped at just above the part here.

07:13

I'm gonna go ahead and go to my position screen

07:15

looking at our distance to go value that we talked about in previous videos.

07:19

Now this is how far our tool is gonna move in the Z axis if

07:23

we were to press that green button one more time while in single block mode,

07:27

and it says we have minus 0.2767 inches.

07:32

If we were to press position again,

07:35

move up and over to our program.

07:38

It's saying that we are should be 0.3767 inches above our jaws.

07:44

We can look above our jaw

07:46

and say, yeah, that looks reasonable.

07:48

That looks correct.

07:50

Once we've gotten to this point, we can press cycle start

07:54

and watch it come down,

07:56

stopping

07:57

at Z 0.1 just like we programmed,

08:01

we can open the doors,

08:03

look in the machine

08:05

and verify

08:06

that everything is where it should be

08:08

and it is, this is the safest way to verify that our work offsets our tool offsets,

08:14

everything match.

08:15

We've done everything right.

08:16

It's time for us to load up our program, run it in graphics and run our part.

08:22

We have gone ahead and clamped on a half inch spacer

08:25

and run a program that cuts our op to jaw force.

08:28

Now,

08:28

we are just giving you this short explanation for now as we'll

08:31

be covering the design and cutting of soft jaws in some detail,

08:35

incoming videos,

08:37

we can now load our part into our jaws and tighten the

08:40

vice handle a reasonable amount while holding our part down firmly.

08:44

We'll take our program from fusion 360

08:47

copy it onto the machine via USB,

08:50

run the program in graphics.

08:53

And if we are satisfied, we'll put the machine in memory mode,

08:56

lower our rapids a bit for our first approach

08:59

and press cycle start.

09:01

Now at this point, I might feed, hold somewhere above our part

09:06

and take a look at our position, screen my distance to go

09:10

and my, my work position.

09:12

And if things are looking good, I'm gonna take the machine out of single block,

09:17

increase my Rapids back up to 100%.

09:19

Press the green button and let things run.

09:26

And if we were a little bit timid about our speeds and feeds, uh,

09:30

we could have reduced our feed rate using those override buttons.

09:34

Heck, you could go all the way down to 50% feed rate if you wanted to

09:38

and then slowly increase the feed rate back up to 100% or more.

09:42

And if we don't like the way things sound

09:44

during this, this time,

09:46

we can adjust our program, go back into fusion 360

09:49

repost it.

09:50

Uh, for this type of part running on aluminum,

09:53

I would probably run at max R PM for whatever machine you have or close to it.

10:00

Now, back on the topic of speeds and feeds.

10:03

If our part had been pulled from the vice and prone

10:07

during machining, we likely didn't tighten our vice enough.

10:11

It's a balancing act too loose and our part could

10:14

come out too tight and we could crush it.

10:17

Now, this part looks great.

10:18

Now, we will know how good things actually are

10:21

when we go to measure it.

10:23

Now, I know this is a lot to take in but realize there are more videos yet to come.

10:27

We're gonna cover all these topics again and again,

10:30

you're doing great.
