Spiral leadin with cut width.
« on: July 12, 2020, 22:16:08 pm »
I needed to machine an outside profile using a cut width greater than the tool diameter.   With Spiral leadin I am seeing a clearance move at each depth increment.  Seems that the Depth First spec is not being followed.  No change with any of the optimization modes.

If I set the stepover to 0, the cut width is ignored, and the profile is machined.  I think this should generate a warning msg.

It's possible to do what I want by two Mops, which is what I ended up doing.

Depth first act only if there is multiple shape in a mop, not on the cut for only one shape.

On your file, just set the "max crossover distance" to 0.7 (the default) instead to 0 and the clearance move will go away ;)

when cutting with "cut width", the width is always cut first.

Thanks for spotting that.  I default crossover distance to zero because with profiles I've had numerous problems crossing between profiles, and I always want spiral leadins not to be interrupted.
