FLOOR FINISHING (Cycle 23, DIN/ISO:

With Cycle 23 FLOOR FINISHING, you can clear the finishing

allowance for floor that is programmed in Cycle 20. The tool

approaches the machining plane smoothly (on a vertically tangential

arc) if there is sufficient room. If there is not enough room, the TNC

moves the tool to depth vertically. The tool then clears the finishing

allowance remaining from rough-out.

Before calling Cycle 23 you need to program further cycles:

Cycle 14 CONTOUR or SEL CONTOUR

Cycle 20 CONTOUR DATA

Cycle 21 PILOT DRILLING, if necessary

Cycle 22 ROUGHING, if necessary

1 The TNC positions the tool to the clearance height at rapid

traverse FMAX.

2 The tool then moves in the tool axis at the feed rate Q11.

3 The tool approaches the machining plane smoothly (on a

vertically tangential arc) if there is sufficient room. If there is not

enough room, the TNC moves the tool to depth vertically.

4 The tool clears the finishing allowance remaining from rough-

5 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.
