Reaming - CYCLE85

Function
With the "Reaming" cycle, the tool is inserted in the workpiece with the programmed spindle
speed and the feedrate programmed at F.
If Z1 has been reached and the dwell time expired, the reamer is retracted at the
programmed retraction feedrate to the retraction plane.
Approach/retraction
1. The tool moves with G0 to safety clearance of the reference point.
2. The tool is inserted into the workpiece with the programmed feedrate F until it reaches
3. Dwell time DT at final drilling depth.
4. Retraction to retraction plane with programmed retraction feedrate FR.

Description
Shank (drilling depth in relation to the shank)
•
The drill is inserted into the workpiece until the drill shank reaches the value
programmed for Z1. The angle entered in the tool list is taken into account.
• Tip (drilling depth in relation to the tip)
The drill is inserted into the workpiece until the drill tip reaches the value
programmed for Z1.
Note: If it is not possible to define an angle for the drill in the tool management, it
will not be possible to select tip or shank (always tip, 0 field)
Drilling depth (abs) or drilling depth in relation to Z0 (inc)
It is inserted into the workpiece until it reaches Z1.
Dwell time at final drilling depth in seconds
Dwell time at final drilling depth in revolutions
the final depth Z1.
1. Select the part program to be edited in the "Program manager"
operating area.
