In this lesson, we’ll be finishing a stock transfer.
00:06
After completing this lesson, you'll be able to: Modify a parting toolpath and create finishing operations.
00:14
In Fusion 360, we want to carry on with our stock handling.
00:18
At this point, we've created our secondary spindle chuck, our parting and spindle return.
00:24
One thing we want to do is we want to go into our Parting toolpath and make an adjustment.
00:28
In the Geometry section, I'm going to add an edge break and allow it to add a small chamfer to the back of the part.
00:35
What this is going to allow us to do is just have a small edge break that we don't have to machine on the part.
00:41
If we rotate this around, we can see a preview of that stock and we can also go in and simulate it if needed.
00:48
But what I want to do here is I want to reconfirm the location that we've asked this to grab onto the part.
00:55
So right now it's based off of the part stock,
00:60
but I'm going to actually set this to the model front and then I'm going to set the chuck plane to an inch and a half back.
01:09
The reason I want to do this is because we're going to have to create a new setup.
01:13
The new setup is going to allow us to machine from the other side.
01:17
We'll have to keep in mind the orientation of the coordinate system for the sub spindle.
01:23
So if we need to flip the orientation, for example, if the Z axis needs to be on this side,
01:29
we need to be aware of that criteria for our specific machine.
01:33
So now that we flip the coordinate system over, we also need to determine where the chuck is located.
01:39
Right now it's based off the model back, so if we rotate this around, it's based off the model back -0.4.
01:48
But remember we actually have positive inch and a half, so it's clamping at an inch and a half in on the part.
01:55
That's important because we want to have an accurate representation on where it's being held.
02:00
The stock in this instance isn't going to matter as much because we're only going to be finishing off this back side.
02:06
But I want to just make sure that I do represent the program number as 1002 and I'm gonna use this as stock transfer.
02:17
If you want to add more detail, you can model the stock and simply fill in that section and you can use from solid.
02:25
But in this instance, I'm just going to use that fixed size cylinder,
02:28
because all I really need to do is finish this chamfered edge and this small recess knowing that we've already drilled the center.
02:36
From here, if we want to face the back, for example, if we parted slightly behind that back face, we could come in and we could clean that face up.
02:46
In this case, I'm going to use profile and allow it to do a profile rough and a profile finish.
02:53
This is going to be internal.
02:55
And keep in mind where the tool’s coming from, positive X, just like it was before.
03:00
But remember that Y is pointing up.
03:03
I need to select a different tool that's going to be okay for that internal profiling.
03:08
So I'm going to grab tool number 5 and just make sure that I am using it in the correct orientation.
03:15
I'm gonna bring this back face up.
03:17
I don't want it to go any deeper than just below that recess.
03:23
And then I'm going to allow it to create that operation.
03:27
Now we are potentially going to have some issues based on the size of the tool.
03:30
That's something that we would want to worry about.
03:33
And then it also is telling us that it's crossing the rotary axis, which is not a big deal in this case,
03:38
because we know that we've already removed material from the center of this.
03:42
Now that we've done our roughing, we can do our finishing operation on the inside.
03:47
Again, this is going to be inside profiling.
03:49
If we need to use a different tool, we can grab a different tool.
03:53
In this case, I don't have any extra tools in the library.
03:56
We have to go into the fusion library and we'd have to filter by our boring tools or our turning general that are based on a specific orientation.
04:07
For example, if we grabbed one of these general tools, we would have to change the orientation of the tool.
04:13
If I set it to 90 degrees, you can see exactly where it is.
04:17
Because we are doing inside profiling, we want to make sure that we are actually using an internal tool.
04:25
So I want to make sure that I am using a boring bar.
04:28
If you don't see those, it's because you likely have filter still turned on.
04:32
So you need to make sure that you do reset those filters and then we'll re-change this back to 0 degrees.
04:39
I'm going to allow it to machine the inside.
04:41
And again, I'm going to have some warnings because we are crossing center but I didn't restrict the plane for this one.
04:48
So I do want to make sure that I don't allow it to cut too deep.
04:52
You want to bring this plane back up and then we can allow it to finish there.
04:58
Again, we will have to deal with some warnings potentially using a smaller tool and not crossing that center will help,
05:05
but we already know how to deal with that warning.
05:07
We can come back and we can modify some of those clearance planes, for example, the inner.
05:14
If we know that the inner is 1/2" or 3/4", we can set those values a bit larger.
05:21
Now the clearance plane sometimes can be a little bit harder to drag, so you might need to grab a few times before you drag it.
05:29
And then if we set those clearance values, that will help us clear some of that warning about crossing the center line.
05:35
Some of the other warnings that we have for clearance radius, we can tilt the tool a little bit, or we can use a smaller insert, smaller tool,
05:43
and that will take care of those.
05:45
Again, these are very specific requirements based on the geometry that you're cutting and the tools that you have available.
05:52
But this is a general look at how we can do that parting in the stock transfer.
05:56
We can setup a new orientation begin machining.
05:60
But it's always important that you understand the coordinate system of the machine that you're working with and its capabilities.
06:06
Because it's very easy to create a toolpath but you need to make sure that you can actually post that.
06:12
And that's the last bit of the puzzle that we want to talk about and that's actually getting your code out.
06:17
So once you finished all of the different toolpaths that you've created, that you need to machine your part, you can create an NC program.
06:26
And inside the NC program, we would want to make sure that we set it to turning or millturn.
06:32
Again, based on the machine capabilities, you would need to select your vendor.
06:36
If you have a specific machine vendor that you're using, then you need to navigate to them.
06:41
And then you would select the machine that fits your specific requirements.
06:46
For example, this is a big part, it might not fit on an ST-10Y.
06:49
But we can select that as our machine, then we can select which operations we want to post.
06:55
Once we select Post and it will create the code and then we can review any warnings that we might have.
07:00
So you'll notice that here the work offset’s not been specified and that's because in the setup it was set at 0 and that's going to cause an error.
07:08
It needs to be set as 1 if we're using G54.
07:12
You also note that this machine doesn't contain a secondary spindle.
07:16
So once again, this is a situation where if we have a machine that doesn't have that capability, it's going to be problematic.
07:24
So what we can do is we can say that we're not actually going to be using that secondary spindle and we can post the code without it.
07:31
One of the benefits of having that NC program is if we have to machine this part on a machine that doesn't have that capability,
07:38
we can make an NC program that makes it very easy for us to modify the code and only post what we need.
07:45
So again, that's the last bit of the puzzle is getting that code out.
07:48
But it's extremely important that one, you know, the capabilities of your machine,
07:53
you have a post that supports it and that you understand the orientation and the limitations of what your machine can do.
08:01
All of those are going to be extremely important criteria when you're setting up your turning operations.
08:06
So from here, make sure that you do save and save often before moving on to some of the practices and challenges that we have in this course.
