N4: Punching and nibbling - only 840D sl
10.5 Rotatable tool
; Activate tangential control with
offset 90°
; Circular interpolation, path
segmentation, 4 strokes are
executed with 90° offset angle
and tangential alignment along
circular path
; Rotation of tool axes to 0°,
stroke
; Activate tangential control with
offset 0°
; Circular interpolation, path
segmentation, 5 strokes with 0°
offset angle and tangential
alignment along circular path
; Position without active
tangential control
; Positioning, C axis rotates to
270°
; Deactivate tangential control
; Circular interpolation, path
segmentation, two strokes without
tangential control where C=270°
; Punching OFF
; Deactivate coupled motion of
rotatable tool axes C/C1
