9.1 The PLANE Function: Tilting
the Working Plane
(Software Option 1)
Introduction
The machine manufacturer must enable the functions for
tilting the working plane!
You can only use the PLANE function on machines which
have at least two tilting axes (head and/or table).
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:
Function Required parameters
SPATIAL Three space angles: SPA,
SPB, and SPC
Two projection angles:
PROJECTED
PROPR and PROMIN and a
rotation angle ROT
EULER Three Euler angles:
precession (EULPR),
nutation (EULNU) and
rotation (EULROT)
VECTOR Norm vector for defining
the plane and base vector
for defining the direction of
the tilted X axis
POINTS Coordinates of any three
points in the plane to be
tilted
RELATIVE Single, incrementally
effective spatial angle
RESET Reset the PLANE function
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.
