13 Digitizing 260
13.1 Digitizing with a Triggering Touch
Probe (Optional)
The digitizing option enables you to reduce a three-dimensional
part into discrete digital information by scanning it with a touch
probe.
The following components are required for digitizing:
■ Touch probe
■ “Digitizing option” software module in the TNC
■ SUSA evaluation software from HEIDENHAIN for further
processing of the data digitized in the MEANDER cycle.
The following cycles are available for digitizing:
■ cycle
■ MEANDER
■ CONTOUR LINES
The TNC and the machine tool must be specially
prepared by the machine tool builder for the use of a
touch probe.
The touch probe must be calibrated before digitizing.
Function
The touch probe scans a 3-D surface point for point in a selectable
grid. The scanning speeds vary from 200 to 800 mm/min with a
probe point interval (PP.INT) of 1 mm (machine-dependent value).
The TNC reads out the digitized positions via data interface,
usually to a PC. You need to configure your data interface
accordingly (see „14.4 Setting the External Data Interface“).
If you want to mill the digitized data subsequently using a tool
whose radius equals the radius of the ball tip, you can machine the
digitized data directly from the file without any further evaluation.
Digitizing cycles are programmed only for the main axes
X, Y and Z.
Coordinate transformations or a basic rotation must not
be active during digitizing.
The TNC also transfers the BLK FORM to the digitizing
data file.
