Cycle run

1 The TNC positions the tool in the tool axis at rapid traverse
FMAX to the entered set-up clearance above the workpiece
surface.
2 The tool reams to the entered depth at the programmed feed
rate F.
3 If programmed, the tool remains at the hole bottom for the
entered dwell time.
4 The tool then retracts to set-up clearance at the feed rate F , and
from there—if programmed—to the 2nd set-up clearance in
FMAX.

Please note while programming:

Program a positioning block for the starting point
(hole center) in the working plane with radius
compensation R0.
The algebraic sign for the cycle parameter DEPTH
determines the working direction. If you program
DEPTH=0, the cycle will not be executed.
Danger of collision!
Use the machine parameter
define whether, if a positive depth is entered, the
TNC should output an error message (on) or not (off).
Keep in mind that the TNC reverses the calculation
for pre-positioning when a
entered. This means that the tool moves at rapid
traverse in the tool axis to set-up clearance
the workpiece surface!
