6.6 Compression of the orientation (COMPON, COMPCURV, COMPCAD)

Compression of the orientation (COMPON, COMPCURV,

NC programs, in which orientation transformation (

programmed using direction vectors, can be compressed if kept within specified limits.

The orientation movement is only compressed if large-radius circular interpolation is active

and depends, therefore, on the G code for orientation interpolation. This can be set via

machine data, as can the maximum path length and a permissible tolerance for each axis or

for the path feedrate for the compressor function. Please refer to the machine manufacturer's

instructions.

Tool orientation

If orientation transformation (

programmed in the following way (independent of the kinematics):

● Programming of the direction vectors via:

● Programming of the Eulerangles or RPY-angles via:

Rotation of the tool

For six-axis machines you can program the tool rotation in addition to the tool orientation.

The angle of rotation is programmed with:

See "Rotation of tool orientation (Page 344)".

NC blocks in which additional rotation is programmed, can only be compressed if the angle

of rotation changes linearly, meaning that a polynomial with

rotation should not be programmed.
