Oblique angle transformation (inclined axis) TRAANG_K

In this chapter, a description is provided as to how an oblique angle transformation
(TRAANG_K) is mapped using a kinematic chain and parameterized in the control system
using system variables.
The system variables are retentively saved in the NC and can be archived and/or read as "NC
data" via SINUMERIK Operate using the commissioning archive.

The oblique angle transformation is a special case of orientation transformation.
The oblique angle transformation is activated using system variable $NT_TRAFO_TYPE =
"TRAANG_K".
