6.15.5 Digitizing with the Measuring Trigger Probe

prerequisites

December 2001

The measuring touch probe permits scanning speeds up to 3 m/min. The

stylus deflection is measured in every direction directly by integral encoders

and evaluated in the TNC.

A "digitizing with measuring touch probe" adapter kit

The machine must be prepared for the use of the measuring touch probe:

Lock the spindle mechanically.

Ensure that the spindle drive cannot be started while the probe is in use.

The "digitizing with measuring touch probe" adapter kit also includes the

"digitizing with TS" function (triggering touch probe).

With MP6200, select whether a measuring or triggering touch probe is

If you wish to use both the triggering and the measuring touch probes, you

must make quite sure that the type of touch probe in the spindle at any

given time is entered in MP6200.

Danger of breakage!

The counting direction of the encoder signals in the probe must match the

counting direction of the encoder signals of the axes. (The axis-specific

parameters are defined in MP210):

Select the POSITIONING WITH MANUAL DATA INPUT mode of operation.

Press the PNT soft key and position the machine by touching the stylus. The

machine must move in the direction in which the stylus is deflected. If that

does not happen: Change the counting direction in MP6320.

With MP6322, assign the touch probe axes (the encoders in the probe) to

the machine axes. For machines with swivel heads:

Enter the respective mounting attitude of the touch probe in MP6322.
