Digitizing
P: PP.INT = Probe point interval
L: L.SPAC = Line spacing
Digitizing Cycle CONTOUR LINES (17)
Cycle 17 CONTOUR LINES enables you to digitize a 3D surface
level by level.
Define Cycle 5 RANGE or 15 RANGE
TOUCH PROBE: Select Cycle 17 CONTOUR LINES
Time limit: If the touch probe has not orbited the model and
returned to the first touch point within this time, the TNC will
terminate the cycle. If you do not want a time limit, enter 0.
Starting point: Coordinates of the starting position
Axis and direction of approach: Coordinate axis and direction in
which the probe approaches the model
Starting probe axis and direction: Coordinate axis and direction in
which the probe begins scanning the model
Feed rate F: Maximum digitizing feed rate
Min. feed rate: Feed rate for scanning the first line
Feed rate reduction at edges: Distance at which the TNC begins to
reduce the scanning feed rate before steep edges
Min. line spacing: Minimum height moved to start the next
line at slightly inclined surfaces
Line spacing and direction: Maximum height moved to start the
next contour line
Max. probe point interval
Tolerance value: The TNC suppresses the storage of probe points
whose distance from a straight line defined by the last two stored
points is less than the tolerance value.
The line spacing and max. probe point interval cannot exceed
20 mm!
