9.2.1 Scanning cycles
Direct access to the position control loop of the TNC controller allows the rapid recording of
measured values (3 to 5 values per second). With a programmed probe point interval of 1 mm, this
produces a scanning feed rate of 180 to 300 mm/min. Three scanning cycles are used for digitizing:
"Range", "Meander" and "Contour Lines".
The "Range" cycle defines the cuboid scanning range and the file where the digitized data are stored.
The "Meander" cycle digitizes a 3-D form
meander-wise (line by line) in the pre-defined
range.

The "Contour Lines" cycle digitizes a 3-D form
level-by-level in contour lines within a pre-
defined range. Level-by-level digitizing is mainly
used for forms with steep edges.

During meander digitizing a very flat surface may cause little movement in the probe axis. This can
result in a lack of lubrication in the probe axis. MP6220 and MP6221 make it possible to lubricate the
axis at the end of the lines.
MP6220
Traverse for lubricating the probe axis at end of line
Entry:
0.000 to 999.999 [mm]
MP6221
Time after which the probe axis must be lubricated
Entry:
0 to 65 535 [min]
