Note
G1 is modal.
The spindle speed S and the direction of spindle rotation M3/M4 must be specified for
machining.
FGROUP can be used to define groups of axes, to which the path feed F applies. You will
find more information in the "Path behavior" section.
Example of milling
Machining of a groove: The tool travels from the starting point to the end point in the X/Y
direction. Infeed takes place simultaneously in the Z direction.
