Touch Probe Cycles: Automatic Workpiece Inspection | MEASURE PLANE (Cycle 431, DIN/ISO: G431)
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.
