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 via Euler angle
ORIRPY via RPY angle (rotation sequence ZYX)
