9.5 Digitizing with the TS 120 Touch Probe (Optional)
The digitizing option enables you to reduce a three-dimensional part
model into discrete digital information by scanning it with the TS 120
triggering 3D touch probe.
The following components are required for digitizing:
• The TS 120 triggering touch probe
• The "Digitizing option" software module in the TNC
• External data storage:
PC (IBM or compatible) with HEIDENHAIN TNC.EXE data transfer
software
• SUSA evaluation software from HEIDENHAIN for further processing of
the data digitized in the MEANDER cycle.
The TS 120 triggering touch probe provides four digitizing cycles:
• TCH PROBE 5.0 RANGE
• TCH PROBE 6.0 MEANDER
• TCH PROBE 7.0 CONTOUR LINES
• TCH PROBE 8.0 LINE
• The TNC and the machine tool must be readied by the machine tool builder for the use of a TS 120 touch
probe.
• The touch probe must be calibrated before digitizing (see page 9-5).
• If you are working alternately with triggering and measuring touch probe systems, ensure that
– you have selected the correct touch probe in MP 6200 (see page 12-4)
– the measuring and triggering touch probes are never connected to the TNC at the same time. The TNC
cannot determine which of the touch probes is actually inserted in the spindle.
Principle
The touch probe scans a 3D surface point for point in a selectable grid.
The scanning speeds vary from 200 to 800 mm/min (when PP.INT = 1 mm).
The TNC transmits the digitized positions as straight-line blocks in
HEIDENHAIN format. The interface function PRINT (see page 11-6)
determines where the blocks are stored:
• Program memory of the TNC
• External storage via RS-232 interface
• External storage via RS-422 interface
• Digitizing cycles are programmed only for the main axes X, Y and Z and for the rotary axes A, B, and C.
• Coordinate transformations or a basic rotation must not be active during digitizing.
