for this practice exercise.
00:07
We're going to start with the supply dataset, collision check dash,
00:10
practice dot f three D.
00:13
Inside of this data set we have two setups op one and op too.
00:17
As we look through here,
00:19
all of the operations are machined but the stock on the
00:22
screen is showing that parts of the operations haven't been completed.
00:26
So we're going to use simulation to verify these
00:29
and make sure that we don't have any problems
00:31
next for op to everything appears to be okay
00:34
but we still want to verify everything in simulation.
00:37
So let's select top one, go to actions and simulate
00:41
and notice that in the very bottom we have a lot of red lines.
00:45
These collisions show that we have a shaft colliding with stock.
00:50
If we take a look at this from a front or a right view,
00:53
the holder has plenty of clearance but it's telling us that
00:56
we have a collision with the shaft of the tool.
00:59
As we pull the tool away, we can see that the cutting flute
01:03
stops short of the top of the part.
01:05
This means that this section is not going to actually cut or remove any material.
01:10
If we were to just play all the way through the tool path,
01:13
it looks like it's fine but this is certainly a problem that we need to adjust
01:17
to fix this. Let's go back and let's select a different tool for the outside.
01:22
So this part starts with facing the top and a two D. Adaptive to clear out the inside.
01:27
It uses the same tool for a two D contour.
01:30
Then it switches over to tool number five, which is a quarter inch end mill
01:35
tool.
01:35
Number five is used to machine the
01:36
outside and then the inside pocket finishing operations
01:40
in this case,
01:40
switching back to the larger half inch end mill tool number one for that.
01:44
Outside contour makes the most sense.
01:46
So let's right click and let's edit this operation.
01:50
We're going to change the tool selection
01:52
and in this case we want to select our tool number one half inch flat
01:56
and our aluminum roughing cutting data
01:58
with no other changes.
01:59
Let's go ahead and rebuild the operations and see if we still have the problem.
02:04
In this case you can see that a small amount of stock is left behind
02:07
but it should be enough cutting flute to cut that
02:10
entire part to fix the stock that's left behind.
02:14
Let's go ahead and edit the tool path
02:17
under our passes section. Let's go ahead and take a look at the roughing passes
02:21
right now.
02:22
The step over is 0.125 which was half of the quarter inch tool but we're going to
02:26
increase that to make sure that the maximum step is half of our half inch end mill.
02:31
We're going to say okay allowed to regenerate and
02:34
because we have stock contours turned on in this operation
02:37
it's not spending a lot of time cutting the outside
02:39
of the part but only focusing where material actually is.
02:43
Let's go ahead and stimulate this operation one more time to verify.
02:46
We no longer have collisions,
02:48
there are no red lines in the bottom and we're going to jump ahead,
02:52
going to the outside contour operation and playing through just
02:55
to make sure that we don't have any problems.
02:59
Everything appears to be okay and the inside of the part is machined properly.
03:03
Let's go ahead and close the simulation and take a look at operation too.
03:08
When we take a look at operation two,
03:10
let's jump into simulation and see if we can find any problems.
03:13
First.
03:14
We have roughing and finishing passes just to take care of this inside opening.
03:17
However, we can see the gray of the model shining through
03:21
This means that we have potentially cut too deep on one
03:23
of our operations but no collisions or warnings were thrown.
03:28
This means that we need to go back to
03:29
that operation and figure out where the problem is.
03:32
So for the operation to D contour three, let's go ahead and edit this
03:37
under the height section.
03:39
Notice that the bottom height is set to selection
03:41
for that face but there is a small offset
03:44
will reset this offset to zero.
03:46
Say okay and allow it to regenerate.
03:49
Then we can select our operation and stimulate one more time.
03:52
I'm going to jump ahead past the roughing operation,
03:55
I'm going to play this slowly and go through
03:58
to just make sure that we don't have any problems.
04:00
You can see now that the green model is showing,
04:03
meaning that we didn't cut too far down into the stock.
04:06
At this point, everything is okay. We can go back to operation one
04:10
and we can save our design before moving on.
