Face Grooving Okuma LB3000 EXII MYW

[Titanium]

Hi, when doing a face groove using IGF, it works well in graphics, including the x and z positions. Somehow, when it goes to the actual cutting on the subspindle, it makes the groove OD too big. The ID is perfect. Does anyone have any tricks to this besides entering the improper numbers?

There are parameters in IGF that determine whether or not the groove cycle is using one or two offsets to control width. is your groove off by one tool width?

My groove is off by 1/2 the tool width. The Id is perfect and the Od of the groove is big.

I don't have access to IGF anymore so I can't look anything up, but I seem to remember this being related to how the offset is specified in the groove cycle.

Okay. That's what I'm working on right now. Thanks Doug.
