So if I understand what you are saying is that for example if you pivot the
head to the mill to 45 degrees (C axis) under servo control. And then move W a
distance of 1.414" at speed S20 then Z and X will each move 1" at S14.412 rate.
Ie:
G01 C45 S10
G01 W1.414 S20
; equivalent to
G01 X1 Z 1 S14.412
Are you just planning on writing a parser that looks for C + W + S values and
creates X,Z and S values? One that takes into considering which tool and adds
that distance into the W move value?
