piece Misalignment
4 The TNC returns the touch probe to the clearance height and
moves the rotary axis, which was defined in the cycle, by the
measured value. Optionally you can have the display set to 0 after
alignment.
 1st measuring point in 1st axis Q263 (absolute):
coordinate of the first touch point in the reference
axis of the working plane.
 1st measuring point in 2nd axis Q264 (absolute):
coordinate of the first touch point in the minor axis of
the working plane.
 2nd measuring point in 1st axis Q265 (absolute):
coordinate of the second touch point in the reference
axis of the working plane
 2nd measuring point in 2nd axis Q266 (absolute):
coordinate of the second touch point in the minor axis
of the working plane
 Measuring axis Q272: Axis in which the
measurement is to be made:
1: Reference axis = measuring axis
2: Minor axis = measuring axis
3: Touch probe axis = measuring axis
 Traverse direction 1 Q267: Direction in which the
probe is to approach the workpiece:
-1: Negative traverse direction
+1: Positive traverse direction
 Measuring height in the touch probe axis Q261
(absolute): Coordinate of the ball tip center (= touch
point) in the touch probe axis in which the
measurement is to be made.
 Setup clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to MP6140.
 Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between tool
and workpiece (fixtures) can occur.
Before programming, note the following
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
Cycle 403 must not be used if the “Tilt working plane”
function is active.
The TNC stores the measured angle in parameter Q150.
