Functionality

Scope of functions
The scope of functions of generic 5-axis transformation covers implemented 5-axis
transformations (see Section "5-axis transformation (Page 145)") for perpendicular rotary axes
as well as transformations for the cardan milling head (one rotary axis parallel to a linear axis,
the second rotary axis at any angle to it, see Section "Cardan milling head (Page 167)").
Applications
In certain cases, it may not be possible to compensate the conventional transformation
machine accuracy, e.g. if:
● the rotary axes are not exactly mutually perpendicular or
● one of the two rotary axes is not positioned exactly parallel to the linear axes
In such cases, generic 5-axis transformation can produce better results.
Programming example
for generic 5-axis transformation is shown in Section "Example for Generic 5-axis
Transformation".
Activation
Generic 5-axis transformation can also be activated like any other orientation transformation
using the TRAORI() or TRAORI(n) command (where n is the number of the transformation).
Furthermore, the basic transformation can be transferred in the call in three other parameters,
e.g. TRAORI(1, 1.1, 1.5, 8.9).
A transformation can be deselected implicitly by selecting another transformation or explicitly
with TRAFOOF.
