5.2.2 Drilling, counterboring CYCLE82

Programming:

CYCLE82 (RTP, RFP, SFD, DEP, RDP, DTB)

Parameters:

                                                   Fig.5.2 CYCLE82

Explanation of the parameters:

1. RTP,RFP,SFD,DEP,RDP, see CYCLE81;

2. DTB(dwell time): The dwell time to the final drilling depth (chip breakage) is programmed under DTB in seconds.

Function:

The tool drills at the programmed spindle speed and feedrate to the entered final drilling depth. A dwell time can be allowed to elapse when the final drilling depth has been reached.

Sequence:

1. Approach of the reference plane brought forward by the safety clearance by using G00

2. Traversing to the final drilling depth with the feedrate (G01) programmed prior to the cycle call;

3. Dwell time at final drilling depth

4. Retraction to the retraction plane with G00

Example:

The program machines a single hole with cycle CYCLE82. The drilling axis is always the Z axis. Programming zero point is the center of end face. Dwell time is 1 second.
