The touch probe moves in the positive direction of
the axis entered under LINE DIRECTION. When the
probe reaches the MAX coordinate on this axis, it
moves by the line spacing (L.SPAC) in the positive
direction of the other axis in the working plane (i.e.
in the column direction). It then moves back in the
negative line direction, and at the other end moves
again by the programmed line spacing.
This process is repeated until the entire range has
been scanned.
While the probe is moving, the coordinates of the
center of the probe tip are stored at intervals equal
to or less than the programmed probe point
interval.
When the entire range has been scanned, the
touch probe returns to the CLEARANCE HEIGHT.
Setting the digitizing parameters:
TCH PROBE: 0 REF PLANE
Select the digitizing cycle 6: MEANDER.
TCH PROBE: 6 MEANDER
Confirm your selection.
LINE DIRECTION ?
Enter the line direction, for example X.
LIMIT IN NORMAL LINES DIRECTION ?
Enter the distance by which the probe is to retract from the surface,
for example 0.5 mm.
LINE SPACING ?
Enter the desired line spacing, for example 0.2 mm.
