Our shop is having a very hard time keeping a .25 plate 17 inches in diameter from relieving itself and springing. Any thoughts on how to machine this stuff? Must be flat within .01 and keep within a .004 thickness tolerance.
Looking for some help. I have an idea of what the MOD function does but I can't seam to find it in the control books. I am trying to help a bud convert an Okuma program over to Fanuc. Please if u could let me know what this is used for and application I would really appreciate it or if it can even be done.
I tried Google for how to calculate a radius based on three points and it looks like there is a formula for it. If u guys could come up with what formulas to use I could definitely write it in macro B for u.
Are they bowing after you cut the slot in them or when you are trying to cut them flat? Sounds like you may have to rough everything out, straighten, then finish the parts in a free state.
Do guys think something like this would work? Right now it would only do 1 straight line but the logic could be written for vertical rows too.

We always get the backlash out of our rotary tables when indexing. This is the only way you can get your positions right on the money and this may be why you are having the issue.
Makinos fanuc controls. Maybe I don't need them but they work with them in there. I'm pretty sure you need the placement of brackets in the right place.
