Sinumerik CYCLE840 Tapping with Floating Tapholder
With Sinumerik CYCLE840 cycle, tapped holes can be produced with floating tapholder
- without encoder
- with encoder.
For tapping without floating tapholder (rigid taping) CYCLE84 is used.
Programming
CYCLE840 (RTP, RFP, SDIS, DP, DPR, DTB, SDR, SDAC, ENC, MPIT, PIT)
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) |
| SDR | Direction of rotation for return Values: 0 (automatic reversal of direction of rotation) 3 or 4 (for M3 or M4) |
| SDAC | Direction of rotation after end of cycle Values: 3, 4 or 5 |
| ENC | Tapping with/without encoder Values: 0 = with encoder 1 = without encoder |
