Description
Converted axis positions
; Tool type end mill
; (z) length compensation vector
; (y) length compensation vector
; (x) length compensation vector
; Radius
; Activate probe
; Oblique plane G17
; Define axes according to the plane
; Entire frame results in
CTRANS(_xx,10,_yy,-1,_zz,5,A,6,B,7)
; Activate all frames and G54
; Set all input values to invalid
; Set measurement type for coordinate
transformation
