Notice:
When you are machining multiple grooves, make sure that there is sufficient clearance from
the spindle as measured from starting position "Reference z0" to allow all parameterized
grooves to be machined. There is otherwise a risk of collision between the tool and the
chuck!
-> Check the plausibility of the input values before pressing <CYCLE START>!
Multiple grooves
The machining sequence is as follows:
1. Starting from the current axis position, the first groove is produced as described under
2. The starting point for the next groove is then approached in the longitudinal axis (X axis),
3. Another complete groove is then machined (as described under "Groove cycle - single").
4. Groove machining and offset in the axial axis then alternate until the number of grooves
5. On completion of the final groove, the original position of the axes before the start of

Description
Groove offset in the longitudinal axis (Z axis): This input value determines the offset
between several identical grooves during production. The direction of the groove offset
between the individual grooves is always towards the chuck.
Number of grooves to be produced. Entering "0" or "1" here has the same effect: A single
groove is produced. When you enter a value of ">1", the appropriate number of grooves is
machined. The input value in parameter "Length I3" defines the necessary offset.
