Please note while programming:
Danger of collision!
You can now also use Cycle 403 when the "Tilt the
working plane" function is active. Ensure that the
clearance height
is sufficiently large so that no collisions
can occur during the final positioning of the rotary axis.
The TNC does not check whether touch points and
compensation axis match. This can result in compensation
movements offset by 180°.
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
The order of the touch points influences the determined
compensation angle. Ensure that the coordinate of touch
point 1 in the axis perpendicular to the probing direction is
smaller than the coordinate of touch point 2.
The TNC stores the measured angle in parameter Q150.
A kinematics description must be stored in the TNC in
order for the compensation axis to be determined
automatically by the cycle.
