Please note while programming:
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
For the TNC to be able to calculate the angular values, the
three measuring points must not be positioned on one
straight line.
The spatial angles that are needed for tilting the working
plane are saved in parameters Q170 – Q172. With the first
two measuring points you also specify the direction of the
reference axis when tilting the working plane.
The third measuring point determines the direction of the
tool axis. Define the third measuring point in the direction
of the positive Y axis to ensure that the position of the tool
axis in a clockwise coordinate system is correct.
