code)
Drilling depth Drilling depth in relation to the tip
FD1 Percentage for the feedrate for the first infeed
DF Percentage for each additional infeed (for swarf removal only) 90 %
V1 Minimum infeed
V2 Retraction distance after each machining step
Clearance distance The clearance distance is calculated by the cycle
362
Drill hole at programmed position.
Position with MCALL
The drill is retracted from the workpiece for swarf removal.
The drill is retracted by the retraction distance V2 for chipbreaking.
