Sinumerik CYCLE84: Advanced Rigid Tapping Cycle for Precision Hole Drilling
Sinumerik CYCLE84 Rigid Tapping Cycle
CYCLE84 produces tapped holes without using a floating tapholder.
CYCLE84 can be applied only if the spindle designated for drilling is capable of working in the position-controlled spindle mode.
Programming
CYCLE84(RTP, RFP, SDIS, DP, DPR, DTB, SDAC, MPIT,PIT, POSS, SST, SST1)
Parameters
| Parameter | Description |
|---|---|
| RTP | Return plane (absolute) |
| RFP | Reference plane (absolute) |
| SDIS | Safety distance (enter without sign) |
| DP | Final drilling depth/elongated hole depth/slot depth/pocket depth (absolute) |
| DPR | Final drilling depth/elongated hole depth/slot depth/pocket depth relative to reference plane (enter without sign) |
| DTB | Dwell time at final drilling depth (chip breaking) |
| SDAC | Direction of rotation after end of cycle Values: 3, 4 or 5 |
| MPIT | Thread pitch as thread size – 3 (for M3) … 48 (for M48) |
| PIT | Thread pitch; values: 0.001 … 2000.000 mm |
| POSS | Spindle position for oriented spindle stop in cycle (in degrees) |
| SST | Speed for tapping |
| SST1 | Speed for return |
