9.2.3 Optimizing the scanning sequence
The following preparations should be made before optimizing machine and controller.
- Set up the flat workpiece with vertical face and plane surface in the machining plane (e.g. XY
plane).
- Probe the surface with probing function "Surface = Datum" ("MANUAL" or "EL. HANDWHEEL
MODE") and enter the reference plane as +0 mm.
- Basic setting of the relevant machine parameters for "Digitizing"
MP6210 = 5 [1/s] Oscillations in normal direction
MP6230 = 30 [mm/min] Feed rate in normal direction
MP6240 = 5 [mm] Maximum stylus deflection
- The interface must be configured according to the type of desired memory for the digitized data
(FE 401 or PC with "Block Transfer" program). See TNC 360 User's Manual.
- Connect FE 401 or PC to the serial data interface if necessary.
- Enter NC program with the scanning cycles "Range" and "Meander" and the scanning direction X
and the probe point interval 1 mm, e.g.
0 BEGIN PGM 1 MM
