Programming technological functions (cycles)
8.1 Drilling
Parameter Description
D Maximum depth infeed - (only when used without compensating chuck, stock removal
or chipbreaking)
Retraction Retraction distance - (for chipbreaking only)
Manual
•
Retraction distance after each machining step (V2)
Automatic
•
Without retraction distance after each machining step
V2 Retraction distance after each machining step – (only without compensating chuck,
chipbreaking and manual retraction)
Distance by which the drill is retracted for chipbreaking.
V2 = automatic: The tool is retracted by one revolution.
DT (only for G Dwell time at final drilling depth in seconds
code)
SR (only for G Spindle speed for retraction - (only for when a compensating chuck is not used)
code)
SDE (only for Direction of rotation after end of cycle:
G code)
