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.
