Example
● Smooth approach (block N20 activated)
● Approach with quadrant (G247)
● Approach direction not programmed, G140 applies, i.e. TRC is active (G41)
● Contour offset OFFN=5 (N10)
NC programming
Programming Manual, 12/2019, 6FC5398-2EP40-0BA0
1. For approach and retraction with straight lines (G147/G148):
Distance of the cutter edge from the starting point of the contour
2. For approach and retraction with circles (G247, G347/G248, G348):
Radius of the tool center point path
Notice:
For REPOS with a semicircle, DISR is the circle diameter
Distance of the end point for the fast infeed motion from the machining plane
DISCL=AC(...) Specification of the absolute position of the end point for the fast
infeed motion
Specification of the absolute position of the end point for the fast infeed motion
Distance of point P1 (retraction plane) from the machining plane
Specification of the absolute position of point P1
Speed of the slow feed movement
The programmed value acts in accordance with the active feedrate type (G
group 15).
The programmed value is interpreted as linear feedrate (like G94) irrespective of
the active feedrate type.
The programmed value is interpreted as revolutional feedrate (like G95) irre‐
spective of the active feedrate type.
