3.7 Selection of working plane (G17 to G19)
Important
In the basic setting, preset for millingG17 (X/Y plane) and G18 (Z/X plane) for turning.
With selection of the tool path compensationG41/G42 (see section "Tool offsets") the
working plane must be specified so that the control can correct the tool length and radius.
Example for milling
The "conventional" approach with milling tool:
• define working plane (G17 basic setting for milling),
• select tool type (T) and tool offset values (D),
• switch on path compensation (G41),
• program traversing movements.

Description
It is advisable to define the working plane G17 to G19 at the beginning of the program. In the
basic setting the Z/X plane is preset for turning G18
