Sinumerik CYCLE84 is used for rigid tapping without compensating chuck.
CYCLE84(RTP , RFP, SDIS , DP , DPR , DTB , SDAC , MPIT , PIT , POSS , SST , SST1 , AXN , PTAB , TECHNO , VARI , DAM , VRT )
Where, RTP- Retraction plane (absolute)
RFP- Reference plane (absolute)
0: corresponds to programmed measuring system inch/metric
CYCLE84(RTP , RFP, SDIS , DP , DPR , DTB , SDAC , MPIT , PIT , POSS , SST , SST1 , AXN , PTAB , TECHNO , VARI , DAM , VRT )
Where, RTP- Retraction plane (absolute)
RFP- Reference plane (absolute)
SDIS- Safety distance
DP- Final drilling depth (absolute)
DPR- Final drilling depth related to reference plane .
DTB- Dwell time at final
SDAC- Direction of rotation after end of cycle
Values: 3, 4 or 5
MPIT-Pitch as a thread size (signed):3: (for M3) to 48: (forM48),
PIT- Pitch of thread size : 0.001........2000.00 mm
POSS -Spindle position for oriented spindle stop in the cycle (in degrees)
SST- Speed for tapping
SST1- Speed for retraction
AXN- Tool axis :
1st geometrical axis (X)
2nd geometrical axis (Y)
3rd geometrical axis (Z)
PTAB- Evaluation of thread pitch PIT :
1: pitch in mm
2: pitch in thread grooves per inch
3: pitch in inches/rotation
TECHNO- Technological settings
VARI - Machining type.
0: tapping in one pass
1: deep-hole tapping with chip breakage
2: deep-hole tapping with chip removal
DAM- Incremental drilling depth
VRT- Variable retraction value for chip breakage
