Tilting The Working Plane Without Rotary Axes - HEIDENHAIN TNC 640 User Manual

Tilting the working plane without rotary axes

Refer to your machine manual.
This feature must be enabled and adapted by the
machine tool builder.
The machine tool builder must take the precise angle
into account, e.g. the angle of a mounted angular head
in the kinematics description.
You can also orient the programmed working plane perpendicularly
to the tool without defining rotary axes, e.g. when adapting the
working plane for a mounted angular head.
Use the PLANE SPATIAL function and the STAY positioning
behavior to swivel the working plane to the angle specified by the
machine tool builder.
Example of mounted angular head with permanent tool direction Y:
Example
N10 T 5 G17 S4500*
N20 PLANE SPATIAL SPA+0 SPB-90 SPC+0 STAY*
The tilt angle must be precisely adapted to the tool
angle, otherwise the control will generate an error
message.
