Geometry settings
8.2 Selection of the working plane (G17/G18/G19)
Meaning
G17
G18
G19
Note
In the default setting, G17 (X/Y plane) is defined for milling and G18 (Z/X plane) is defined
for turning.
When calling the tool path correction G41/G42 (see Chapter "Tool radius compensation
(Page 289)"), the working plane must be defined so that the controller can correct the tool
length and radius.
Example
The "conventional" approach for milling is:
1. Define working plane (
2. Select tool type (
3. Switch on path correction (
4. Program traversing movements.

Comment
; Selection of working plane X/Y, call tool. Tool
length compensation is performed in the Z
direction.
; Radius compensation is performed in the X/Y
plane.
; Circular interpolation/tool radius compensation
in the X/Y plane.
