Coordinate transformations (frames)
12.2 Frame instructions
Applications
• Offset the zero point to any position on the workpiece.
• Align the coordinate axes by rotating parallel to the desired working plane.
Advantages
In one setting:
• Inclined surfaces can be machined
• Drill holes with various angles can be produced
• Multi-face machining can be performed
Note
Depending on the machine kinematics, the conventions for working plane and tool offsets
must be taken into account for the machining in inclined working planes
