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. Input range
-99999.9999 to 99999.9999

Set-up clearance

Q320 (incremental): Additional

distance between measuring point and ball tip. Q320
is added to MP6140. Input range 0 to 99999.9999;
alternatively PREDEF

Clearance height

Q260 (absolute): Coordinate in the

touch probe axis at which no collision between touch
probe and workpiece (fixtures) can occur. Input range
-99999.9999 to 99999.9999; alternatively PREDEF

Traversing to clearance height

Q301: Definition of

how the touch probe is to move between the
measuring points:
0: Move at measuring height between measuring
points
1: Move at clearance height between measuring
points
Alternative: PREDEF

Set to zero after alignment

Q337: Definition of

whether the TNC should set the display of the C axis
to zero, or write the angular misalignment in column
C of the datum table:
0: Set the display of the C axis to zero and write the
value in line 0 of the datum table
>0:Write the measured angular misalignment with
correct algebraic signs in the datum table. Line
number = value of Q337. If a C-axis shift is registered
in the datum table, the TNC adds the measured
angular misalignment.
