_APZ, _APZA, _APX, _APXA (blank definition)
You can also define a blank by entering the dimensions
of a blank cylinder (or hollow cylinder) or as an
allowance on the finished-part contour in parameters
_APZ and _APX.
You can enter the cylinder dimensions as either
absolute or incremental values, although an allowance
on the finished-part contour is always interpreted
incrementally.
Absolute or incremental values are selected via
parameters _APZA and _APXA
(_APZA, _APXA: 90 - absolute 91 - incremental).
