Siemens Sinumerik CYCLE83 Peck drilling cycle makes deep hole drilling easy, Very flexible drilling cycle gives cnc machinists full control over all aspects of deep hole drilling tasks.
CNC machinists can control whether they want to retract tool every time to start-point for chip-removal or they can set for just chip-breaking, this way tool will just retract 1 mm for next peck.
Siemens Sinumerik CYCLE83 Deep-Hole Drilling
The tool drills at the programmed spindle speed and feedrate to the entered final drilling depth.
Deep hole drilling is performed with a depth infeed of a maximum definable depth executed several times, increasing gradually until the final drilling depth is reached.
Siemens Sinumerik CYCLE83 Deep-Hole Drilling Cycle Format
CYCLE83(RTP, RFP, SDIS, DP, DPR, FDEP, FDPR, DAM, DTB, DTS, FRF, VARI)
RTP Retraction plane (absolute)
RFP Reference plane (absolute)
SDIS Safety clearance (enter without sign)
DP Final drilling depth (absolute)
DPR Final drilling depth relative to the reference plane (enter without sign)
FDEP First drilling depth (absolute)
FDPR First drilling depth relative to the reference plane (enter without sign)
DAM Amount of degression (enter without sign)
DTB Dwell time at final drilling depth (chip breaking)
DTS Dwell time at starting point and for swarf removal
FRF Feedrate factor for the first drilling depth (enter without sign) Range of values: 0.001 … 1
VARI Machining type (Chip breaking=0, Swarf removal=1)
Parameter VARI – Machining type
Chip breaking=0 (see figure below)
Swarf removal=1 (see above figure)
The drill can either be retracted to the reference plane + safety clearance after every infeed depth for swarf removal or retracted in each case by 1 mm for chip breaking.
