• Plane
The coordinate system rotation is executed on the selected plane (G17, G18, and
G19) when G68 is commanded.
The G code for selecting a plane (G17, G18, or G19) can be specified before the
block containing the G code for coordinate system rotation (G68).
• Cutter compensation C
Cutter compensation operations are executed after the coordinate system is
rotated.
• Notes about the coordinate system rotation
Order of command
Note
1. When a decimal fraction is used to specify angular displacement (R_), the 1’s
digit corresponds to degree units.
2. Please do not command other than a plane selection, the rotation center
coordinates, and the rotating angle in the block of G68.
3. Specify G69 in a separate block.
4. Please command the plane selection command (G17, G18, G19) in the G69
mode.
Other notes
Please refer to notes in clause 2.15.4.
