Plane Selection; G17, G18, G19 - Mitsubishi Electric MELDAS C6 Programming Manual

6. Interpolation Functions

6.3 Plane selection; G17, G18, G19

Function and purpose
The plane to which the movement of the tool during the circle interpolation (including helical
cutting) and tool diameter compensation command belongs is selected.
By registering the basic three axes and the corresponding parallel axis as parameters, a plane can
be selected by two axes that are not the parallel axis. If the rotary axis is registered as a parallel
axis, a plane that contains the rotary axis can be selected.
The plane selection is as follows:
• Plane that executes circular interpolation (including helical cutting)
• Plane that executes tool diameter compensation
• Plane that executes fixed cycle positioning.

Table 1 Example of plane selection parameter entry
As shown in the above example, the basic axis and its parallel axis can be registered.
The basic axis can be an axis other than X, Y and Z.
Axes that are not registered are irrelevant to the plane selection.
