2.12 Coordinate transformations (frames)
In this example, identical shapes are ma‐
chined in two workpiece surfaces perpendicu‐
lar to one another via subprograms. In the new
coordinate system on the right-hand work‐
piece surface, infeed direction, working plane
and the zero point have been set up as on the
top surface. Therefore, the conditions required
for the subprogram execution still apply: Work‐
ing plane G17, coordinate plane X/Y, infeed
direction Z.
Comment
; Working plane X/Y, workpiece zero
; Subprogram call
; Absolute offset of the WCS
; Additive rotation of the WCS around Y through 90°
