surface rough pocket

[Harbec Users]

This may be an old problem, but I didn't see it on the board. We're having trouble with surface rough pocket gouging. Different depth cuts results in gouges in different spots. Any help???

Thanks...Don

what version MC are ya using?

[Harbec Users]

it's happened in both MR1 and a system with just SP1. We've had this problem before as well. It's cutting right through a drive surface in the middle of it all.

Seeing that more often here in X as well. It used to happen to me sporadicly in 9 when using the auto-detect flats option. Happens now in X without using it. Ive had it happen on 4 different parts in the last month and a half. Changing stepdowns a slight ammount will usually fix the toolpath, but that doesnt help the part that just got scrapped on the machine.

I change stepdown a bit and I have also found changing %stepover to work as well.

Good luck...

What about gap settings?

Have you tried increasing this?

Thanks for all the input. It seems like a bug after reading all the responses. I've changed steps and tolerances only to have it gouge different areas. The final solution was to send it back to Mcam9 where it wrote beautifully.

I think the only times we've had this happen was with a flat endmill. Maybe that's the culprit???

I talked with some other users here and the problem has happened with ball endmills as well.
