Further information
General
It is recommended that the working plane G17 to G19 be selected at the start of the program.
In the default setting, the Z/X plane is preset for turning G18.
The control system requires the specification of the working plane for the calculation of the
direction of rotation. Additional information is provided in the section "Circular interpolation
(Page 188)".
Machining on inclined planes
Rotate the coordinate system with ROT (Page 316) to position the coordinate axes on the
inclined surface. The working planes rotate accordingly.
