; Coupling group for a non-circular machining
; XACH is the infeed axis of the grinding disk
; CACH is the workpiece axis as rotary axis and master value axis
; Application: Grind non-circular contours
; Table 1 maps the override for axis CACH as function of the position of CACH
; Overlay of the XGEO axis with handwheel infeed for scratching
