Wear comp with tools near hole size

It clears the hole....multi-passes, it clears out of the hole...

Not 1 pass on that threadmill...only has 3 threads on it, so it's a couple passes

Any way to force it to stay down with multi passes?

No

Not without a hand edit

So the best cycle combination is the most inefficient, Mcam 2021 update?  Hope so.....

Just add a checkbox "Chip clearing" Or a field for "radius sweep angle" for gentle entry into the cut.

I could attach more examples but it doesn't look like you want that (btw its pretty much the same for all holes). And thats 1-64 threads to 2" npt holes in various materials. The only thing that changes is the goofy tools we use on different holes.

Again, reach out to your reseller of QC at Mastercam dot com...that's how change gets implemented

They do listen, some of the suggestions I made in 2014 made it to 2018 for lathes.

FYI I don't use the rough cuts, I put a zero on that parameter.  I only use finish passes.  Why?  I don't remember exactly, but when I used rough passes it did some funky stuff that I didn't like.

I do the same. I usually do 2 passes per hole and my threadmills are conventional cutters so they all cut top down instead of bottom up.

It might be possible to have a Post Edit do this for you. What does the NCI output look like?

What exactly do you mean "stay down"?  The way I do it it stays down, it doesn't rapid out of the hole.  It goes to the point where the tool clears the part, then it goes back down.

 

Perhaps you can post a file?

Could that funky stuff have included the tool retracting between passes?

Possibly, but I really don't recall.  I don't understand what the purpose of the rough passes is.

These settings make the path move left on the red line,then back to center, then arc smoothly into the cut.

I'm not sure if this is sufficient to satisfy wear comp on this control I haven't tested it.
