Lathe CAM Inside Turning Collision on retract

[sdvdl]

I am doing a boring operation (Profile Roughing; Inside Turning) that leaves .004" stock for a finishing pass. This path works fine. I then created a derived operation for Profile Finishing to clean up the remaining stock. This results in a massive collision between the tool and the wall of the bore upon retraction. Super weird since the operation from which this is derived works with no collision. I've tried a bunch of things, particularly on the Linking tab-->Lead-Out section, but nothing seems to work. Any ideas?

I change your Clearance to "Inner Radius" and gave it an offset of -.06. I also set your Lead-Out move to be the same as the Lead-In. Result:

 

You still end up with collisions, but that's because your insert is diving straight into material left from the drill point. I suggest either drilling slightly deeper with the drill, or pulling your "Back" height setting in your ID Boring operations.

Thanks for the quick, detailed response. It works. I'm still perplexed that collisions were introduced when derived from a non-colliding pass -- -I'm really just trying to clean up a roughing pass here. I see that the Linking tab of the Finishing strategy is missing the Clearance section of the Roughing strategy. No idea why, but I guess herein lies the difference. Honestly, I think I'm going to just uncheck Stock to Leave on the roughing strategy and be done with it. I don't trust the Finishing pass, given that I can't actually control the lead out.

As for the collision at the bottom of the hole, I took care of that by selecting Drill Tip Through Bottom. Thanks for pointing that one out.
