; Retraction with a quadrant
; Approach with a semi-circle
; Retraction with a semi-circle
; Approach and retraction in space (basic setting)
; Approach and retraction in the plane
; Approach and retraction with straight lines (G147/G148): Distance of the cutter edge from the start
or end point of the contour
; Approach and retraction along circles (G247, G347/G248, G348): Radius of the tool center point
path
; Distance of the end point for the fast infeed motion from the machining plane (safety clearance)
; Speed of the slow infeed motion
The programmed value acts according to the active command of the G group 15 (feed: G94, G95)
See the following illustration for approaching along a straight line using the example of G42 or retraction using G41 and
completion with G40:
