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.
