The cycle automatically divides cutting into roughing, finishing and fine-finishing.
Sparking-out strokes can be programmed for the end of each stage.
Off-loading is also possible at the end of the roughing and finishing stages.
Dressing strokes can be programmed to take place prior to each technology step.
Sequence
Approach allowance position, approach X starting position and Z starting position.
Start oscillating motion, infeed at reversal points.
The first infeed once oscillating motion has commenced is adjusted to ensure that all
additional infeed operations correspond to the infeed amount. This process is also performed
following interruptions, intermediate dressing and deselection of the handwheel override
function.
The oscillating motion is not performed with the oscillation function, as this would cause
problems in terms of residual path deletion, and would overload the PLC.
Following interruption/dressing, an off-loading value is applied as the tool approaches the
machining start point.
At the end, the tool retracts to the starting position.
