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!

You can only use the PLANE function on machines which
have at least two tilting axes (head and/or table).

Function

Required parameters

Soft key

SPATIAL

Three space angles: SPA, SPB, and SPC

PROJECTED

Two projection angles: 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.
