3.2 Presetting automatically

8 New datum for reference axis Q331 (absolute):

Coordinate in the reference axis at which the TNC

should set the stud center. Basic setting = 0

8 New datum for minor axis Q332 (absolute):

Coordinate in the minor axis at which the TNC should

set the stud center. Basic setting = 0

8 Measured-value transfer (0, 1) Q303: Specify

whether the determined datum is to be saved in the

datum table or in the preset table:

-1: Do not use. Is entered by the TNC when old

programs are read in (see “Saving the calculated

datum” on page 64).

0: Write determined datum in the active datum table.

The reference system is the active workpiece

coordinate system.

1: Write determined datum in the preset table. The

reference system is the machine coordinate system

(REF system).

8 Probe in TS axis Q381: Specify whether the TNC

should also set the datum in the touch probe axis:

0: Do not set datum in the touch probe axis

1: Set datum in the touch probe axis

8 Probe TS axis: Coord. 1. st axis Q382 (absolute):

Coordinate of the probe point in the reference axis of

the working plane at which point the datum is to be

set in the touch probe axis. Only effective if Q381 = 1.

8 Probe TS axis: Coord. 2. nd axis Q383 (absolute):

Coordinate of the probe point in the reference axis of

the working plane at which point the datum is to be

set in the touch probe axis. Only effective if Q381 = 1.

8 Probe TS axis: Coord. 3. rd axis Q384 (absolute):

Coordinate of the probe point in the reference axis of

the working plane at which point the datum is to be

set in the touch probe axis. Only effective if Q381 = 1.

8 New datum for touch probe axis Q333 (absolute):

Coordinate in the touch probe axis at which the TNC

should set the datum. Basic setting = 0

8 No. of measuring points (4/3) Q423: Specify

whether the TNC should measure the stud with 4 or

3 probing points:

4: Use 4 measuring points (standard setting)

3: Use 3 measuring points (standard setting)

Example: NC blocks
