Practice exercise

00:01

This is a practice exercise video solution

00:06

for this practice exercise.

00:07

We're going to be using this supply dataset, exhaust flange

00:10

F three D.

00:11

You also want to make sure that you have the process planned sample open as well

00:15

to get started.

00:16

We want to measure this part to see the sizes

00:19

of drill bits and tools that we need to manufacture it

00:22

so to get started, we want to go to inspect and measure,

00:25

We're going to begin taking a look at the size of the ports.

00:28

We can see the diameter here is 45 mm.

00:32

This means that we can use a relatively large tool, something that is 10

00:36

and above to finish these ports.

00:39

We also want to make sure that we take a look at some of the external radi I on our part.

00:43

We can see here that the diameter is 20.

00:47

If we use an exact match tool, such as something like a 20 millimeter diameter tool.

00:53

This means that we're likely to get chatter in the corners.

00:56

So this tells me that I want to use something

00:58

such as a 15 millimeter or smaller to give me

01:02

a little bit of a difference between the radi i on the part and the radius of my tool.

01:07

Next I want to take a look at the holes in this case,

01:10

you can see the diameter is 10 millimeters.

01:13

This means that we can use something like a

01:18

We also need to identify the holes on the bottom side that are slotted

01:22

once again.

01:23

This is the same diameter,

01:24

which means that we can likely pre drill these and take a smaller tool in

01:28

such as an eight millimeter end mill to clean those holes up.

01:32

The last thing that we want to do is double check the overall height of our part.

01:35

We can see here that it's 15 mm,

01:38

which means that we need a tool to stick out of the

01:41

holder at least that amount in order to cut the entire profile.

01:45

Now in most cases, a part like this would be done by using a laser cutter or a water jet.

01:51

But we are going to be programming it with tool paths so

01:54

we want to make sure that we identify the appropriate tool sizes.

01:57

We want to take all of that information and make sure

01:60

that we do populate a process plan to prepare for machining.

02:04

So in the case of our part we're going to do a spot drill for setup one.

02:09

The tool is going to be a 10 millimeter spot drill

02:12

and I'm going to set this as a tool number one.

02:15

Next.

02:16

What we want to do is we want to drill the holes again, set up number 1,

02:22

and this will be tool number two.

02:24

Next we're going to be roughing the ports. These are the large openings in the part.

02:29

Again,

02:29

we're going to be doing this in setup number one and

02:31

for now I'm just going to say 15 millimeter end mill.

02:35

I'm going to set this as tool number three.

02:38

Next we're going to rough the outside of my part.

02:41

Now the outside is going to require a smaller tool for

02:44

finishing but we can use that same 15 millimeter end mill

02:48

to go ahead and rough those areas.

02:51

Next we want to finish off the ports on the inside.

02:54

These ports are going to be done with a smaller end mill

02:57

in this case will put in an eight millimeter end mill.

02:59

Since we know that those holes are 10 millimeters,

03:02

we're going to set this at tool number four and finally we're going to finish

03:06

the outside and once again we're going to use that same eight millimeter tool.

03:11

Now the ports themselves are relatively large.

03:14

We can take any size end mill in there to finish those ports off.

03:17

However, in order to finish the ports and the holes on the inside of our part,

03:22

we need to make sure that we are thinking about tool changes and understanding

03:26

the time that it's going to take to change tools on the machine and whether or

03:30

not we want to do that back and forth and how that affects the overall program

03:34

At this point we could finish off the entire inside

03:37

of the part with that 15 millimeter en mail but

03:40

this is a great starting point to remind us what

03:42

tools we need when we get to program our part,

03:45

make sure that you do save the process plan before moving on to the next step.
