PROGRAMMING

L98 Deep Hole Drilling Cycle

This cycle is for drilling deep holes or for drilling in

materials with bad cutting property.

With the parameter R11 the retraction movement

can be determined.

Chip breaking (R11=0)

The drill dives into the work piece to the first drilling

depth (R25), dwells (duration R27), retracts 1 mm

and dives in again.

Retracting (R11=1)

The drill dives into the work piece to the first drilling

depth (R25), dwells (duration R27), retracts out of the

drilling hole (to R22), dwells (duration R28), and

dives in again.

The following infeed is always smaller for the value

R24 than the previous. The sequence infeed - retrac-

tion will be repeated until the end depth is reached..

If the calculated infeed is smaller than R24, it will be

constant with the value R24.

If the remaining infeed down to end depth R26 is

smaller than the double degression value (2xR24),

the remaining infeed will be halved and worked off in

two infeeds.. Therefore the smallest infeed never can

be less than R24/2.
