ANGULAR TRANSFORMATION OF
AN INCLINE AXIS
With the angular transformation of an incline axis, it is possible to make movements along an axis
that is not perpendicular to another. The movements are programmed in the Cartesian system and
to make the movements, they are transformed into movements on the real axes.
On certain machines, the axes are configured in a Cartesian way, they are not perpendicular to each
other. A typical case is the X axis of a lathe that for sturdiness reasons is not perpendicular to the
Z axis.
Programming in the Cartesian system (Z-X) requires activating an angular transformation of an
inclined plane that converts the movements of the real (non-perpendicular) axes (Z-X'). This way,
a movement programmed on the X axis is transformed into movements on the Z-X' axes; i.e. it then
moves along the Z axis and the angular X' axis.
Turning angular transformation on and off.
The CNC assumes no transformation on power-up; the angular transformations are activated via
part-program using the instruction G46.
The angular transformations are turned off via part-program using function G46. Optionally, a
transformation may be "frozen" (suspended) to move angular axis by programming in Cartesian
coordinates.
Influence of the reset, turning the CNC off and of the M30.
The angular transformation of an incline axis stays active after a RESET, M30 and even after turning
the CNC off and back on.
