Polar coordinate interpolation (G12.1, G13.1)

An interpolation between a rotary axis and a linear axis in the machining plane is
switched on and off through G12.1 and G13.1. A further linear axis is perpendicular
to this plane.
Linear or circular interpolation using coordinates in a Cartesian coordinate system
is applied in order to program a linear axis together with a rotary axis (virtual axis).
This function corresponds to the TRANSMIT function within Siemens mode.
Note
For a detailed description of the TRANSMIT function see "SINUMERIK
840D/810D(CCU2)/FM" NC Functional Description, Extended Functions" chapter
"Kinematic Transformation (M1)" and "SINUMERIK 840D/810D/FM--NC Program-
ming Guide Production Scheduling (PGA)" chapter "Transformation".

Caution
!
When specifying G12.1, the plane (G17, G18, G19) which has been used pre-
viously is canceled.
NC Reset will cancel the polar coordinate interpolation mode and re--establish the
previously selected plane.
