6.15.4 Digitizing with the Touch Trigger Probe
Technical
prerequisites
6 – 360
For digitizing, HEIDENHAIN recommends the TS 220 touch trigger probe.
Touch probes with infrared transmission are not suitable for digitizing because
the operating time is limited by the battery charge. Such systems with battery
charge run in continuous operation for no more than eight hours.
n
Integrating the software module "Digitizing with TS." If the module is
already installed, the following appears beneath the NC and PLC software
numbers when you press the MOD key:
%00000001 (see software option, Id. Nr. of the logic unit).

Optimization for operation with following error
The digitizing process is optimized by machine parameter:
7 7 7 7
In MP6210, enter the probing rate during scanning of the model (number of
oscillations in normal direction per second).
MP6210 depends on the dynamic behavior of the machine. The k
affects the dynamic behavior (operation with following error): The higher the
k
factor, the greater the number of oscillations.
v
Together with the probe point interval PP.INT, MP6210 determines the
maximum scanning feed rate of the "meander" and "contour line" probing
cycles:
F
[mm/min]
=
probe
This results in the formula for the calculation of the value to be entered in
MP6210. The optimized scanning feed rate depends on the feed rate in normal
direction (MP6230).

In MP6230, enter the feed rate in normal direction.
The feed rate in normal direction (MP6230) is the velocity with which the touch
probe moves perpendicularly to the contour from the non-deflected to the
deflected condition and vice versa.
