6.10 Oversizes
Axis-parallel oversize G57
G57 defines different oversizes for X and Z. G57 is programmed
before the recessing or roughing cycle.
Parameters
 X oversize X (diameter value)
 Z oversize Z
The following cycles take the oversizes into account:
„ Roughing cycles: G81, G817, G818, G819, G82, G827, G828, G829,
G83
„ Recessing cycles: G86x
„ Recess turning cycles: G81x, G82x
The cycles G81, G82 and G83 do not cancel the oversizes after
execution of the cycle.
Example: G57

If the oversizes are programmed with G57 and in the
cycle itself, the cycle oversizes apply.
