Re: thread milling?

Hi RatonLaveur, Imagine you take one of those multi cut tools and perform a single helix operation, with height equal to the tool's pitch, then disengage. The resultant thread count will match the number of cutting edges on the tool. If you go more than that height, you end up taking a number of cut...

Re: thread milling?

My most recent Harvey Tool email reminded me that thread cutting tools come in flavors with more than one cutting edge. I'm not sure how that effects the Path Op. https://embed.widencdn.net/img/harveyperformance/jeu1xbpmjd/exact/Harvey_Threading_ThreadMillingCutters_MultiForm_Sm.png?position=c&c...

Re: LibLathe - Lathe Path Generation

I agree. In concept, I would assume that any model would require alignment so it is aligned—and centered on—the z axis, in the job setup. As you mentioned, with user option to reverse between +/- z. Broadly, most job models milled in Path are generated in FC, so in many cases, this isn’t an issue. A...

Isn't the axis of rotation always around the Z axis?

The horizontal Z-axis on the lathe strikes me as a local coordinate system that job models are translated to align. What is different about this compared to machining jobs that require aligning the model to face toward +Z?

Re: thread milling?

I'm in no real rush, but figure it's a good capability to have in FreeCAD, so I'm glad you've taken a pass at it. Hope you're back up and milling sooner than later!

Re: thread milling?

I'd forgotten about it, but I'm pretty sure you'd been kind enough to mention it before. Hope you're well Dan.

Re: Dressup Tag bit compensation has an error

Hi Markus, Sorry, I missed your reply until today. I get you on all points. I didn't actually do anything with tool type--other than to point out that it's relatively straight-forward to generate, and to show in a sketch how the compensated paths for the meaningful tool types would work. I agree wit...

Re: Dressup Tag bit compensation has an error

Hi Brad, I dug into the PathDressupTag.py and I made some changes,, but I'm not sure how to try it out in place of the comiled version. I know I got through the syntax errors though... I saw what you were doing, and kept the output of TagSolid.__init__ the same--Cylinder, Cone, or Sphere for degener...
