This is a practice exercise video solution

00:05

for this practice. Let's get started with the supply data set.

00:08

Simple part CM practice dot F 3D.

00:11

We're gonna be creating tool pass to machine

00:13

a simple part from a single orientation.

00:15

So to get started, we're gonna navigate to the manufacture workspace.

00:19

We're gonna make sure that our units are set to inch

00:23

and make sure that we're in the milling section before we select set up.

00:27

We're gonna begin by navigating to the stock and

00:30

we're gonna change the side stock offset to zero,

00:34

but we are going to allow a small amount of stock on the top of the part.

00:38

This allows us to reference this corner as our XYZ zero

00:42

and we can go back to our setup and use the

00:44

box point option to put it in the back left corner.

00:47

We also want to make sure that we move to our post

00:50

process section and we're gonna modify our program number to 20001.

00:57

And we're gonna have a comment of simple

01:02

We're gonna set our W CS offset at one which represents

01:06

G 54 on a standard hoss machine and we'll select,

01:09

OK.

01:09

Next,

01:10

we need to begin programming our part and we're gonna start by using

01:14

two D and face to clear off the top of our stock.

01:17

We're gonna select all our tools from the standard Fusion 3 60 library.

01:21

So we'll select Fusion 3 60.

01:23

We're gonna filter by flat end mill

01:25

and we're gonna select a half inch flat end mill.

01:28

We're going to use aluminum finishing as

01:30

our cutting data preset and we'll hit select

01:33

now that we have a tool.

01:34

All we really need to do for a facing operation is say OK,

01:38

because the stock size is selected by default,

01:41

if we want to increase the step over for the tool, because this is a pretty small step.

01:46

We can always go back into our tool path, we can go to our passes section

01:51

and we can take a look at our setup for step over.

01:55

Now,

01:59

go over half of the tool or quarter inch.

02:02

This will reduce the amount of time it takes to face the top of our part.

02:06

Next,

02:06

we're going to carry on with that half inch

02:08

N mel and I'm gonna begin by roughing the outside

02:12

to do this. I'm gonna select two D adaptive clearing using that same tool.

02:17

I'm gonna select this face noting that the edge

02:20

around the cylindrical portion of our design shows up as

02:24

a darker Blue Fusion 3 60 knows that this is an open pocket and it'll treat it as such,

02:30

which means the tool can venture outside of that area.

02:34

We want to make sure that in the past section, we do have stock to leave.

02:37

We'll come back and finish this off with another tool

02:40

we'll select, OK. And allow it to rough that geometry.

02:44

With this tool still selected, we're gonna go to two D and select two D contour

02:49

with two D contour.

02:51

We can select an edge and we can create a tool path that cuts exactly to that edge.

02:56

We have another tool path option that we can use.

02:58

So let's hit, cancel and take a look at our two D pocket.

03:02

While two D pocket can be used for roughing tool pass.

03:05

It can also be used for a finishing tool path

03:07

that allows us to create a finishing pass around the center portion of our design,

03:12

but also allows it to create additional passes to clear out this bottom face.

03:17

We want to make sure that we take a look at our passes section,

03:21

we toggle off stock to leave

03:23

and we're gonna select, OK.

03:26

Notice that on the outside corners,

03:28

it's only doing a small pass instead of going all the way around our part.

03:32

If we were to use a two D contour,

03:34

it would require multiple passes and it would take more time for our cut.

03:38

So, what we're gonna do now is select our two D adaptive clearing

03:42

and we're gonna clear out the inside of our part.

03:45

And then we're gonna select our two D pocket tool path,

03:48

select the inside pocket. And once again, make sure that stock to leave is turned off

03:53

and allow it to finish the inside.

03:56

We can validate this by selecting the entire

03:58

setup going to actions and selecting simulate.

04:02

I'm gonna jump ahead one tool path at a time starting with our facing

04:05

two D adaptive on the outside,

04:08

our two D pocket to finish the outside,

04:10

two D adaptive on the inside and two D pocket to finish the inside.

04:14

Because everything is shown in green with the colorization set to comparison.

04:18

This means that we've machined all the way down to the underlying 3D model.

04:23

Now we can exit the simulation and we can save our tool path.

04:27

The next step from here would be to create an NC program,

04:29

create our setup sheet and export our NCG code.

04:33

We're not going to be doing that in this practice.

04:35

But it's a good idea for you to play around and

04:37

practice those steps as they are required to manufacture your parts.

04:41

But at this point, once everything's saved, go ahead and move on.
