The PLANE Function: Tilting
the Working Plane (Software
Option 1)
Introduction
The PLANE function is a powerful function for defining tilted working
planes in various manners.
All PLANE functions available on the TNC describe the desired working
plane independently of the rotary axes actually present on your
machine. The following possibilities are available:
The machine manufacturer must enable the functions for
tilting the working plane!
Function
Required parameters
Soft key
Three space angles: SPA, SPB, and SPC
Two projection angles: PROPR and
PROMIN
Three Euler angles: precession
(EULPR),
Norm vector for defining the plane and
base vector for defining the direction
of the tilted X axis
Coordinates of any three points in the
plane to be tilted
Single, incrementally effective spatial
angle
Use the PLANE SPATIAL function if your machine features
Cartesian rotary axes. SPA stands for rotation of the A axis,
SPB
the B axis and SPC the C axis. Because you always
have to enter all three angles, define the angle to be 0 in
any axes that are not available on your machine.
