So I'm trying to eliminate arcs in rough turning toolpaths and did notice an option under the Compare & Edit dialogue called Make Sharp Corners. I expected this to work as it does in milling, but it seems to have zero effect. This would make the code at the machine much simpler for the operator to make adjustments on or just following the coded toolpath.
This has Make Sharp Corners turned on:
Hi Neal
I have created a ticket for this issue, with the reference CAM-8283.

The make corners sharp is already exposed in the Fusion turning UI. So I would think the plan was to expose if in the HSMWorks UI also at some point. Not that it works in Fusion either.

I guess to clarify I would expect it to make corners sharp as the corner condition, same as in milling. As stated in the original post, it is to simplify the code to get as clean and unfettered a toolpath as possible.
I said it right in the initial post: trying to eliminate arcsin roughing passes 
Yeah I understand... but that setting isn't meant to do what you think it's meant to do... either way, it doesn't work. It should only show up in the UI, when In Control, Wear, or Inverse Wear is selected. You can see its the same parameter in Fusion Turning Profile as it is in 2D Contour:
You can also see the correct behaviour for this setting if you use it with 2D Contour. In the image below you can see it appearing and disappearing... its the same in Fusion 2D contour, I just checked. What you are after for Profile is the setting in the drop-down menu, which I highlight in the green box. Make Sharp Corners and the values in that drop-down do totally different things.
This is the effect of the Make Sharp Corner setting in 2D Contour. Also note that the external corner remains an arc, because the drop-down setting is the default "Roll around corner".
It doesn't work in Turning Profile... because it doesn't do this.... although the internal corners are sharp anyway in turning profile, because it isn't applying the comp rad... at least it isn't with Tip Tangency set for the insert definition.

The behavior from this setting is what Scott Moyse is describing, it is for keeping inner corners sharp when using in control or wear compensation.
We are considering adding a setting for sharp outer corners in turning. The reference CAM-8283 can be used to track the new feature for sharp outer corners.

@BjoernJohnsson please can you create a couple of tickets for this 'Make Sharp Corners' setting in turning, because it's not working. The first issue is it shouldn't show in the UI when comp is set to In Computer... second, activating 'Make Share Corners' has no impact on the toolpath because the internal corners are already square in turning... possibly because compensation isn't working correctly.
And please, make sure that the 'sharp outer corners' is implemented consistently with the UI on the milling side.
