9.15 General workpiece data – CYCLE420
Cylindrical grinding

Programming and Operating Manual, 07/2009, 6FC5398-4CP10-2BA0
Example for the general workpiece data
CYCLE420 must be written at the start of each machining program.
In the example, dressing is to be performed after every second machined workpiece using a
dressing amount of X_AB=0.3 mm and two dressing strokes. The longitudinal position must
be acquired for each newly clamped workpiece.

Sequence of operations
In this cycle, the general prerequisites for the machining are set:
Counting of the workpiece cycles and optional call of the dressing program CYCLE416.
It can be selected whether or not longitudinal positioning using the probe is required to
detect the clamping tolerance in Z. The clamping difference determined is loaded into G507
as the additive Z work offset.
During the further program sequence, the workpiece spindle is started and the coolant
turned on.
Prerequisites for longitudinal positioning using a probe:
The caliper must be calibrated in the setup. The values for the work offset, X-Pos and Z-Pos,
are saved.
