Transformations
6.2 Three, four and five axis transformation (TRAORI)
Description
5-axis programs are usually generated by CAD/CAM systems and not entered at the control.
So the following explanations are directed mainly at programmers of postprocessors.
The type of orientation programming is defined in G code group 50:
ORIEULER
ORIRPY
ORIVIRT1
ORIVIRT2
ORIAXPOS
ORIPY2
Machine manufacturer
The machine manufacturer can use machine data to define various variants. Please refer to
the machine manufacturer's instructions.
Programming in Euler angles ORIEULER
The values programmed during orientation programming with
Euler angles (in degrees).
The orientation vector results from turning a vector in the Z direction firstly with
Z axis, then with
