In this last video we're going to cover the final of the finishing operations, the chamfering. So to do so, let's start out by adding a new folder, a group. And we are going to rename this and let's do the logical thing and call it chamfering. So we're going to use a couple of different methods for chamfering here.

The first one is going to be the obvious route, we're going to use the inbuilt chamfering tool. So we'll go to add operation and under rest machining we go to chamfering. And we need to reorient this because we want it to chamfer the elements in this face. So let's set that to 90.

And the chamfering's actually got a pretty good auto detection system in there. So if we click on recognize, we can see that it's got everything that we want along with a couple of extras. But again, that's not the end of the world. So if we just select the extras and delete them.

Now I like to think those two are pretty obvious because there's no way you can get to them through this. I also want to get rid of these two here and that's because we're going to be working on this one. And I'd like to get rid of this as well. But beyond that, everything else here is pretty much as we want it.

So I'm going to click on generate toolpath. And yeah, that looks pretty good. So let's take a quick look at how it simulates. And we're going to simulate up to current operation.

Let's wait for that to finish chewing through and then press run. I'm going to speed this up a little bit. That looks pretty good to me. You can see it's just taking the lightest cut off of there, which is exactly what we asked it to do.

And everything is looking nice. So we'll speed this up a little bit. I'm not seeing anything to be concerned by in any of this. Looks pretty good to me.

So yeah, we've got all of our chamfering for that part sorted. So I'm going to go back into machining and under transformations, we're going to multiply the toolpath on the a-axis by 180 degrees. And we'll have two counts of it. And we'll press generate.

And you can see, obviously, we've done as we have done multiple times before in this job. And we've gotten ourselves a nicely duplicated set of chamfer paths. Now, the last bit of chamfering we're going to be working on is going to be on this top face here. And we're going to take a slightly different approach this time.

We're not going to use the chamfering tool because that can't really handle radial transformations interpolated through the cut. Instead, we are going to go to 4D rotary and we're going to use 4D contouring. Now, of course, it's decided that we're trying to use a different tool, which we're not going to. So I'm going to go back into the tools menu and I'm going to grab the 4mm conical mill.

I'm going to select that tool. Now, under job assignment, we are going to take a quick look at our options here. We've got edge or curve on surface. We have 5D curve and we have drive faces, which is where we're looking at the moment.

Edge curve on surface is very much as one would expect. It's typically either an edge or a curve artifact, usually on something cylindrical. 5D curves, again, that's a manually driven, more complicated curve, typically best applied on more cylindrical surfaces than this. Again, that is something that you can, of course, pretty much bend to your will if needs be.

But for the sake of ease of use, we're going to use drive faces here. So I am going to select this chamfer face and we're going to use smooth to propagate out the selections, go all the way around as we have there. And I'm going to click on drive faces and we're going to click on generate. Now, obviously, this isn't quite ideal as a toolpath.

So we're going to make a slight change at this point. Under strategy, we're going to change tool orientation to rotary axis to normal to surface. And the reason for this is to rotary axis is obviously very well suited to things that are perfectly cylindrical. However, because this is a little bit more rectilinear than that, normal to surface means that we can make full use of X and Y translation at the same time, as well as Z translation if required.

So that's what this is doing in this instance. So if we simulate this now, and we're running a bit slow, so you can see what I'm on about here. And if we click on run at this point, so once it's pulled away and come back, you'll see. As the workpiece moves, you can see that the tool head is also moving as well.

So the A axis is not the one doing all of the work in this instance. If we'd left this as being to rotary axis, then the head would stay in a relatively fixed position moving only really in Z, not at all in Y, which is what we needed to do for a shape like this. So telling it to move relative to the surface normal gives us an optimal result here. And with that, we have reached the end of this project.

This is the final operation now. And I'm pretty convinced that this is going to come out exactly how we want it to. I'm going to speed this up a little bit now. And I'm going to check verify compare.

Bear in mind, we didn't simulate the second set of chamfers over here. So that'll come up in blue. But we can see a very, very tiny amount of blue. But we can see that this exterior chamfer is looking good generally.

I hope this project has been informative. And obviously, if you have any questions or there's anything you wish to explore further, please do not hesitate to reach out to us and let us know. Thanks for your time.
