                                                          MDEP- Minimum drilling depth .
                                                          VRT - _____ (skip)
                                                          DTD- _____ (skip)
                                                          DIS1-_____(skip)

Deep-hole drilling with chip removal (VARI=1):            More examples..........!!!!

● Approach of reference plane shifted by the amount of the safety clearance with G00

● Traversing to the first drilling depth with G01, whereby the feedrate results from the

feedrate programmed during the cycle call that is compensated with the FRF (feedrate

factor) parameter.

● Execution of dwell time at final drilling depth (DTB parameter).

● Retraction to the reference plane shifted by the amount of the safety clearance with G00

for chip removal.

● Execute dwell time at starting point (DTS parameter).

● Approach of the last drilling depth reached, minus the limit distance, programmable or

calculated within the cycle, with G00.

● Traversing to next drilling depth with G01 (motion sequence is continued until the final

drilling depth is reached).

● Retraction to the retraction plane with G00.

Deep-hole drilling with chip breakage (VARI=0):         More examples..........!!!!

● Approach of reference plane shifted by the amount of the safety clearance with G00

● Traversing to the first drilling depth with G01, whereby the feedrate results from the
feedrate programmed during the cycle call that is compensated with the FRF (feedrate
factor) parameter.

● Execution of dwell time at final drilling depth (DTB parameter).

● Variable retraction (Parameter _VRT) from the current drilling depth with G01 and the
feedrate programmed in the calling program (for chip breakage).

● Traversing to next drilling depth with G01 and the programmed feedrate (motion sequence
is continued until the final drilling depth is reached).


● Retraction to the retraction plane with G00.
