p Probing technique
Direction errors are generated when probing paths are so close to part
surfaces that direction changes cannot be verified. The examples that
follow illustrate incorrect and then correct probing paths for the
verification of horizontal direction changes.
To specify a probe direction factor:
U Highlight the Dir. Factor field
U Use the numeric keypad to enter the minimum number of counts in
the new direction. This number should typically be 40 or greater.
U Press the ENTER key
Incorrect probing technique.The
probe is lowered too close to the
part surface, detection of probe
direction change is impossible. Correct probing technique. The
probe is lowered far enough from
the part surface, detection of
probe direction change is
possible
