See the following illustration for parameters for CYCLE83:
D e ep-hole drilling with chip breakage (VARI=0)
● Approach of the reference plane brought forward by the safety clearance by using G0
● Traversing to the first drilling depth with G1, the feedrate for which is derived from the feedrate defined with the program
call which is subject to parameter FRF (feedrate factor)
● Dwell time at final drilling depth (parameter DTB)
● Retraction by 1 mm from the current drilling depth with G1 and the feedrate programmed in the calling program (for chip
breaking)
● Traversing to the next drilling depth with G1 and the programmed feedrate (sequence of motions is continued until the
final drilling depth is reached)
● Retraction to the retraction plane with G0
Explanation of the parameters
