17.2.13 Inclined Surface Machining Command
M720VW
M system △
L system ―
This function is to define the new coordinate system (called the "feature coordinate system") which was
created by rotation and reference position translation of the X, Y, Z axes of the original one (before the
inclined surface machining command was applied). By using this function, an arbitrary spatial plane can be
defined, and machining on that plane can be carried out with normal program commands.
Also, the tool axis can automatically be controlled to the + Z direction of the newly defined feature coordinate
system. Since the feature coordinate system will be re-created in accordance with the tool axis direction,
machining programs can be developed without the need to consider the direction of the feature coordinate
system and rotation of the tool axis.
This function is available only for the 5-axis machining.

The feature coordinate system is defined in the following method.
- Designation with Euler angle.
- Designation with the roll angle, pitch and yaw angle.
- Designation with the three points on the plane.
- Designation with two vectors.
- Designation with a projection angle.
- Designation with the tool axis direction.
