00:22
We're going to be taking a look at the
00:23
general process to create a handful of tool paths,
00:26
but we're not going to be covering all tool paths available.
00:29
We first want to begin with the turning face tool path.
00:32
This will allow us to prepare the end of our stock,
00:35
making sure that we have a nice clean surface for
00:37
anything like drilling or boring the center of a part.
00:40
We first need to select a tool.
00:43
In this case,
00:43
we're gonna be going into our document and we want
00:46
to select the general tool number two and hit select.
00:51
We don't need to make any selections because Fusion 3 60 already knows
00:55
where the end of stock is as well as the end of part,
00:57
we just need to verify some of the motions.
00:60
And in this case, we're going to go into geometry.
01:02
Noting that it's automatically grabbing the front of our model
01:05
in the radii section.
01:07
We wanna make sure that the different values are going to give
01:10
us enough clearance and enough safety before we begin entering the part.
01:15
Each time we talk about things like the retract and the outer limits of our part,
01:19
these are going to determine where the tool rapids or feeds to.
01:23
So keep in mind that making them too large
01:25
or too small could potentially cause a collision,
01:28
especially if your tool can't slow down quick enough.
01:31
We're going to move over to the passes section
01:33
note that we're gonna be going outside to inside
01:37
and also note that the values that we're gonna be using for the passes
01:41
are going to allow for the standard numbers that come directly from our tool.
01:46
Last linking allows us to go to and from the safe Z distance.
01:52
And that's gonna be the distance that's out here as defined in our setup.
01:56
We're gonna say, OK, leaving all the rest of the defaults
01:59
and note. Now, we can see that the tool comes in,
02:01
moves in and creates our cut
02:04
and we can verify this later on when we begin talking about simulation.
02:08
But note that with lathe,
02:09
we're actually looking at a cross section of the part you can see shown in darker blue
02:15
and we've got the yellow section representing the stock that remains,
02:19
we can use the stock visibility to turn on or off the stock preview,
02:23
but this will still leave this yellow section showing us where stock still remains.
02:28
The next thing that we wanna do is talk about external profile,
02:32
roughing and finishing
02:33
the turning profile, roughing will allow us to rough out the part
02:38
and then we can go back with a finishing tool path.
02:41
Once again, we're gonna use the same tool note.
02:43
Now we see slightly different settings.
02:46
We're gonna be going outside. We're not doing profiling inside of our part.
02:50
And we're gonna leave the tool orientation as default.
02:53
Some machines will allow you to adjust the angle of the tool.
02:57
But in this case, we're going to assume that our tool is fixed,
03:00
we're gonna move over to the second section
03:03
and we're gonna take our back plane.
03:05
Remembering that we actually have some obstruction here with the jaw.
03:09
And what we're gonna be doing is making sure that we're clear of that Chuck plane
03:14
and we're gonna be starting all the way at the front.
03:17
We don't need to worry about any additional offsets or extensions.
03:20
We're gonna simply say, OK, leaving all of the default settings
03:24
we can see here now that the tool is moving
03:27
from left to right or right to left,
03:29
depending on our settings and it's moving in the X direction,
03:32
removing that material.
03:34
Once again, if we zoom in,
03:35
we can see the material that's left behind and we
03:37
can see that the tool slightly dropped into that groove
03:41
there are options for groove suppression if we go back to our passes
03:45
and we can allow it to skip over any grooves
03:48
or we can allow it to drop into those.
03:51
If we go back into our tool path under our geometry section,
03:54
we can toggle on groove suppression and we can allow it to skip those areas.
03:59
This will allow us to avoid specific areas of a tool path.
04:03
But in this case, because this back wall is shared,
04:06
it's not going to allow us to suppress just that area.
04:09
But that's OK because this tool can't go very deep into that groove.
04:13
It will allow us to come back and do a clean up pass.
04:17
The next thing that we want to do is repeat this process.
04:19
But this time we're gonna be using profile finishing,
04:22
we're gonna use the same tool in this instance.
04:25
But in some cases,
04:26
you might find that you'll use a different tool between roughing and finishing
04:30
for our geometry. Once again that back plane, we're gonna be moving forward
04:35
and under our passes section,
04:37
we want to make sure that we are making sharp corners,
04:40
a spring pass will allow us to go back.
04:43
No dragging. This will allow us to avoid dragging the tool up a face.
04:49
But we're going to leave these options as default and say, OK,
04:52
this goes back and it cuts the rest of the material
04:54
that was left behind with the exception of that one groove
04:58
Now, let's go to our turning options and let's take a look at doing a groove tool path.
05:03
We've got groove finishing.
05:05
We've also got turning groove and turning single groove,
05:08
depending on the layout of your model.
05:10
This will determine which one of these options you'll be using.
05:13
I'm gonna select turning single groove.
05:15
Then from our tool selection, we're gonna go in and select our OD grooving tool.
05:20
If we take a quick look,
05:21
we can see the width of the tool is 0.125 and there is a small corner radius.
05:26
We're gonna select it.
05:27
Then we need to move on to our geometry selection,
05:31
gonna rotate the model just slightly
05:33
and I'll be selecting that inside edge.
05:35
When we go back to a top view,
05:38
you can see here.
05:38
Now the tool comes in, moves into that position and it'll pull back out.
05:43
We have groove side alignment as middle and tip and we'll say, OK,
05:47
and just take a look at the preview.
05:49
When we look at the preview, you can see that the tool is actually offset forward.
05:54
It's centered on our selection. So we need to go back into our settings
05:58
back into the geometry.
06:01
And this time instead of middle, we can do a back or a front alignment.
06:06
When we do a front alignment,
06:07
it moves the tool all the way forward and we do a back alignment,
06:10
it moves the tool all the way back.
06:12
We're gonna say OK, and allow it to regenerate that tool path.
06:16
We can see now that we were able to remove all the material.
06:20
But there are other tool paths that we do want to talk about.
06:23
We do have a tool path for turning champ for.
06:25
Now, the profiling tool path will allow us to take care of large model champers.
06:30
But an actual champ for tool path will allow us
06:33
to come back and just simply break those edges.
06:36
We want to make sure that we do go back to our general turning tool.
06:41
Then we want to select our geometry. And for this, I'm gonna select the front edge,
06:46
this back edge and I'll select this front edge as well.
06:49
And then we need to specify the size. I'm
06:52
gonna go with a relatively small champer of 0.04 at 45 degrees and say, OK,
06:58
now we have a warning telling us it failed to generate.
07:00
Now,
07:01
one thing we always have to be careful with is the
07:03
orientation of our tool relative to what we're trying to cut.
07:07
If we go back into the two D
07:09
Cher
07:09
tool path, and we
07:10
deselect this edge here and say, OK,
07:12
it's able to generate.
07:14
So part of the problem that we have is this specific tool isn't able to cut that champ
07:20
at 45 degrees here.
07:21
So if we wanted to clean that corner up,
07:23
we would have to come back with a different tool in order to do it.
07:27
Keeping in mind that this is a relatively small champ for close to a wall.
07:31
So it would need a very specific tool.
07:34
Now that we've processed most of the model,
07:36
let's come back and let's do a threading tool path here
07:40
under the turning section. We're gonna select turning thread
07:44
and then we need to select a specific turning threading tool.
07:48
We're gonna select OK, and take a quick note of the thread pitch being 0.05
07:53
we're gonna select our geometry.
07:57
And then on the radii, we're going to leave all these settings as default
08:01
for passes.
08:02
We have a thread depth of 0.04 by default and a
08:05
thread pitch of 0.05 which comes directly from our tool.
08:09
We're going to say OK and allow it to generate that tool path.
08:13
When we look here,
08:14
we can see that it's starting from the front of our part and moving through,
08:18
but it doesn't extend past the end
08:21
in order to adjust that we need to go back into our settings.
08:24
And in our geometry, we need to include a small backside offset
08:28
because that's an eighth of an inch gap.
08:30
We're gonna say 0.06 allowing it to extend just barely and say OK,
08:36
validating the tool path that was created here will need to be done with simulation.
08:41
As this preview we see on the screen is not gonna
08:43
be able to let us know what that thread looks like
08:46
we can turn in process stock back on.
08:49
But once again,
08:50
it's not gonna be able to verify or validate that threading tool path.
08:54
I'm gonna toggle this back off for now.
08:56
And the last tool path that we do want
08:58
to identify is something called a parting tool path
09:01
in general.
09:02
When you're creating a lathe part, at the very end,
09:05
you'll likely be using a parting tool path to
09:07
remove the part from the rest of the stock.
09:09
In
09:09
this specific case,
09:11
what we actually did was we have the chuck on this portion of our part,
09:15
which means that we can't actually select the back
09:17
edge to remove it from the rest of stock.
09:20
But we are gonna select turning part,
09:22
we need to use an appropriate tool.
09:24
And in most cases, a grooving tool or a very specific parting tool will be used.
09:29
We'll select this
09:31
and note that by default, it's going off of the back of the part.
09:35
We can move that in a specific amount if we wish and part it off sooner.
09:40
But in general, it will be the back of your digital model.
09:44
I gonna say, OK, and allow it to generate,
09:46
noting that we have now gone through and removed this
09:49
portion of our design from the rest of the stock
09:53
at this point.
09:53
Let's make sure that we do save our design before we move
09:56
on and start talking about simulating tool paths and generating our documents.

05:13
I'm gonna select turning single groove.
05:15
Then from our tool selection, we're gonna go in and select our OD grooving tool.
05:20
If we take a quick look,
05:21
we can see the width of the tool is 0.125 and there is a small corner radius.
05:26
We're gonna select it.
05:27
Then we need to move on to our geometry selection,
05:31
gonna rotate the model just slightly

and I'll be selecting that inside edge.
05:35
When we go back to a top view,
05:38
you can see here.
05:38
Now the tool comes in, moves into that position and it'll pull back out.

Now,
07:01
one thing we always have to be careful with is the
07:03
orientation of our tool relative to what we're trying to cut.
07:07
If we go back into the two D
07:09
Cher
07:09
tool path, and we
07:10
deselect this edge here and say, OK,
07:12
it's able to generate.
07:14
So part of the problem that we have is this specific tool isn't able to cut that champ
07:20

07:40

07:44
and then we need to select a specific turning threading tool.
07:48
We're gonna select OK, and take a quick note of the thread pitch being 0.05
07:53
we're gonna select our geometry.
07:57
And then on the radii, we're going to leave all these settings as default
08:01
for passes.
08:02
We have a thread depth of 0.04 by default and a
08:05
thread pitch of 0.05 which comes directly from our tool.
08:09
We're going to say OK and allow it to generate that tool path.
08:13
When we look here,
08:14
we can see that it's starting from the front of our part and moving through,
08:18
but it doesn't extend past the end
08:21
in order to adjust that we need to go back into our settings.
08:24
And in our geometry, we need to include a small backside offset
08:28
because that's an eighth of an inch gap.
08:30
We're gonna say 0.06 allowing it to extend just barely and say OK,
08:36
validating the tool path that was created here will need to be done with simulation.
08:41
As this preview we see on the screen is not gonna
08:43
be able to let us know what that thread looks like
08:46
we can turn in process stock back on.
08:49
But once again,
08:50
it's not gonna be able to verify or validate that threading tool path.
08:54
I'm gonna toggle this back off for now.
08:56
And the last tool path that we do want
08:58
to identify is something called a parting tool path
09:01
in general.
09:02
When you're creating a lathe part, at the very end,
09:05
you'll likely be using a parting tool path to
09:07
remove the part from the rest of the stock.
09:09
In
09:09
this specific case,
09:11
what we actually did was we have the chuck on this portion of our part,
09:15
which means that we can't actually select the back
09:17
edge to remove it from the rest of stock.
09:20
But we are gonna select turning part,
09:22
we need to use an appropriate tool.
09:24
And in most cases, a grooving tool or a very specific parting tool will be used.
09:29
We'll select this
09:31
and note that by default, it's going off of the back of the part.
09:35
We can move that in a specific amount if we wish and part it off sooner.
09:40
But in general, it will be the back of your digital model.
09:44
I gonna say, OK, and allow it to generate,
09:46
noting that we have now gone through and removed this
09:49
portion of our design from the rest of the stock
09:53
at this point.
09:53
Let's make sure that we do save our design before we move
09:56
on and start talking about simulating tool paths and generating our documents.
