CNC Programming Left Hand Right Hand

CNC Programming Left Hand Right Hand

(OP)
If I prepare a machining drawing tabulated left hand and right hand, can a CNC programmer take advangtage of this, or do they have to write two programs?

RE: CNC Programming Left Hand Right Hand

Fanucs have a mirror function about the x and/or y axis. I suspect most VMC controllers have this.

RE: CNC Programming Left Hand Right Hand

I wonder if it applies to generated threads. I always looked forward to someone putting LH threads in the opposite hand part.

can a CNC programmer take advantage of this

Every machine controller I've ever touched has had mirror functions, and so has every CAD program. I've done this a bunch and never had an issue with having to rework things for a left hand part.

It can - smart programmers will set up generated threads as a subroutine anyway, in which case they would not be mirrored.

RE: CNC Programming Left Hand Right Hand

Inspectors should fail parts until engineers put an explicit note "OPPOSITE EXCEPT SCREW THREADS."

Time to start that revolution!
