SIDE FINISHING (Cycle 24, DIN/ISO:
G124)
Cycle run
With Cycle 24 SIDE FINISHING, you can clear the finishing
allowance for side that is programmed in Cycle 20. You can run this
cycle in climb or up-cut milling.
Before calling Cycle 24 you need to program further cycles:
Cycle 14 CONTOUR GEOMETRY or SEL CONTOUR
Cycle 20 CONTOUR DATA
Cycle 21 PILOT DRILLING, if necessary
Cycle 22 ROUGHING, if necessary
Cycle run
1 The TNC positions the tool above the workpiece surface to the
starting point for the approach position. This position in the
plane results from a tangential arc on which the TNC moves the
tool when approaching the contour.
2 The tool then advances to the first plunging depth at the feed
rate for plunging.
3 The contour is approached on a tangential arc until the entire
contour is completed. Each subcontour is finished separately.
4 Finally, the tool retracts in the tool axis to the clearance
height or to the position last programmed before the cycle.
This depends on the parameter ConfigDatum, CfgGeoCycle,
posAfterContPocket.
