Hey Everyone,

I am taking a CAD/CAm class and the instructor asked a
very interesting question. One that he didn't even know the answer to.
So maybe someone out there knows???? What the G & M stand for in G code
and M code?????????????????????LC



I was told that the G codes were "Geometry" and the M codes "Miscellaneous"
Now, I can't verify that those are the correct terms but some years ago that
is what I was told. Of course, some G codes now handle jumps and
sub-routines which have been added to the capabilities of the CNC controllers. M codes
still seem to do miscellaneous tasks such as starting spindles, tool
changes, coolant, program end and in some cases, jumps, sub-routine calls,
sub-routine end, etc.
