8.4 Processing Related to the RTCP Function
The other geometric processing that can be associated with the RTCP function is as
follows:
- part on inclined plane,
- table off-centering,
- tool length correction,
- tool wear offset,
- tool correction in space.
8.4.1 Part on Inclined Plane
When the part to be machined rests on an inclined plane, this plane is specified by
a pivot point declared in the programming syntax by PD followed by the three
components of a translation vector and by one or two inclinations defined by PI, PJ
or PK followed by the cosine and sine of the angles. This translation vector positions
the pivot point with respect to the programme origin and the pivot point becomes the
new programme origin.
