Traverse direction 1 Q267: Direction in which the
probe is to approach the workpiece:

-1

: Negative Traverse direction

: Positive traverse direction

Measuring height in the touch probe axis Q261
(absolute): Coordinate of the ball tip center (=
touch point) in the touch probe axis in which
the measurement is to be made. Input range
-99999.9999 to 99999.9999

Set-up clearance Q320 (incremental): Additional
distance between measuring point and ball tip.
Q320 is added to

SET_UP (touch probe table). Input

range 0 to 99999.9999

Clearance height Q260 (absolute): Coordinate in
the touch probe axis at which no collision between
touch probe and workpiece (fixtures) can occur.
Input range -99999.9999 to 99999.9999

Traversing to clearance height Q301: definition
of how the touch probe is to move between the
measuring points:

: Move at measuring height between measuring

points

: Move at clearance height between measuring

points

Preset value for rotation angle Q307 (absolute):
If the misalignment is to be measured against a
straight line other than the reference axis, enter
the angle of this reference line. The TNC will
then calculate the difference between the value
measured and the angle of the reference line for the
basic rotation. Input range -360.000 to 360.000

Preset number in table Q305: Enter the preset
number in the table in which the TNC is to save the
determined basic rotation. If you enter Q305=0,
the TNC automatically places the determined basic
rotation in the ROT menu of the Manual Operation
mode. Input range 0 to 2999
