Multiple axismachining
12.2 The PLANE function: Tilting the working plane (software option 8)
Tilt 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 into account e.g.
the precise angle of a mounted angular head in the
kinematics description.
You can also align the programmed working plane perpendicular to
the tool without rotary axes, e.g. for 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:
NC syntax
N10 T 5 G17 S4500*
N20 PLANE SPATIAL SPA+0 SPB-90 SPC+0 STAY*
The swivel angle must be precisely adapted to the
tool angle, otherwise the TNC outputs an error
message.
