Hi, so this video is going to be about chamfering and best practices for breaking sharp edges on your workpiece. Fortunately, chamfering is actually quite an easy process in ENCY so this should be fairly quick. So the first thing that we're going to do is identify the edges that we wish to break on this, and as far as I'm concerned, it's going to be the surrounding slots, the edges of these upper bores, and the edges around these castellations. These are what I'm most interested in focusing on.

So to facilitate ease of selection of all of these, I've switched off select faces because grabbing faces does kind of mess with the auto detection of how chamfering works, and it can produce some funny results. So we're going to add an operation now, and it's under rest machining that we want, and we're going to click on chamfering here. Now, as you can see, it's finally selected the correct tool automatically; it's our 10mm conical mill, this is ideal for our needs. So what we need to do now is under job assignment, we are going to have to grab all of these edges.

Now we can try using recognize, but that does sometimes come up with some spurious results, and ideally, I don't want to bother playing around with these lower edges in the castellations because obviously, the tool is not going to be able to fit in there properly. So for the moment, we're going to look at doing manual selections, and the way that we do this is exactly how I've selected curves in every other operation; we just click on the relevant edges. Now this is going to take a second, but we will grab all of them as a result. So with some forms as well, it is possible to double click to auto chain all of the edge results and unless you are absolutely 100% certain in how the model you're working on has been constructed, it's often more trouble than it's worth.

If, however, you're the person that drew the model, you know exactly how it was put together, then you may find it's a bit of a time saver to do so. So that's all of the edges that we need to select covered there, so we're now going to add sharp edge, and that should grab all of them, and it will tell you the various different heights that the edges in question are at. It may not be a bad idea to group them according to height, but for the sake of this exercise, I'm not too worried about it. Under strategy, we want to set the chamfer depth and the tool contact point.

Obviously, if you're not using a 45-degree tool, that tool contact point can make quite the difference, but in this instance, that's not the case. The chamfer depth is 0. 5mm; that's pretty much ideal, so I'm going to say we can probably generate a path based on this, and we can then simulate it. So if we generate the current tool path.

Now one thing that it is worth noting about chamfering is it is technically a gouge as opposed to a clean operation. Unless your part has actually got chamfers built into the design technically you are cutting into the part so ENCY will tell you about that. If you want to eliminate this particular red node and stop it from coming up again, you can switch it off. So under parameters, you can turn off check for gouges under the simulation feature, and you see that now comes up as a clean node.

It remains in the master node there that can probably be resolved by re-simulating the whole thing although in the background ENCY will be aware of the fact there are gouges in your model. I don't generally recommend turning off gouge detection just because it's there for a reason, and it does preserve your parts, but in this particular instance, it's the only real way in which one can eliminate that particular complaint. So if we go into simulation now and we simulate up to current operation, and we slow this right down, and then we click on run. Possibly not slow it down that much.

Let's drift it a little bit further, and we speed it up slightly. And we can see now that we're just doing a very nice clean, just the gentlest of touches on the edge of the piece which is pretty much perfect for our needs. That's exactly what a chamfering pass should look like, and this will of course break the majority of the sharp edges that you're going to be dealing with. So I'm going to speed this up, let it run through its thing, and once it's done, we can come back and take a look at it, and we can then start focusing on the content of the next video which is going to be text engraving.

So I shall see you in the next one.
