10.2.2 Plane selection: G17 to G19
Functionality
To assign, for example, tool radius and tool length compensations, a plane with two axes is
selected from the three axes X, Y and Z. In this plane, you can activate a tool radius
compensation.
For drill and cutter, the length compensation (length1) is assigned to the axis standing
vertically on the selected plane (see Section "Tool and tool offsets"). It is also possible to use
a 3-dimensional length compensation for special cases.
Another influence of plane selection is described with the appropriate functions (e.g. Section
"Support for the contour definition programming").
The individual planes are also used to define the direction of rotation of the circle for the
circular interpolation CW or CCW. In the plane in which the circle is traversed, the abscissa
and the ordinate are designed and thus also the direction of rotation of the circle. Circles can
also be traversed in a plane other than that of the currently active G17 to G19 plane (see
Section "Axis Movements").
The following plane and axis assignments are possible:
