Digitizing
P: PP.INT = Probe point interval
L: L.SPAC = Line spacing
Digitizing Cycle MEANDER (16)
Cycle 16 MEANDER is for digitizing a 3D contour in a series of
back-and-forth line movements.
Define Cycle 5 RANGE or 15 RANGE
TOUCH PROBE: Select Cycle 16 MEANDER
Line direction: Coordinate axis in whose positive direction the
probe moves after touching the first contour point
Scanning angle: Direction of touch probe traverse relative to
the axis entered in line direction
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 distance moved forward to start the
next line at steep surfaces
Line spacing: Max. distance moved forward to start the next 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!
• Set a line direction that is as perpendicular as possible
to steep surfaces!
