Compensating workpiece misalignment by rotating the C axis
Q260 Clearance height? (absolute): coordinate in
the touch probe axis at which no collision between
tool and workpiece (fixtures) can occur. Input range
-99999.9999 to 99999.9999
Q301 Move to clearance height (0/1)?: 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
Q337 Set to zero after alignment?: 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
>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.
