Manual operation and setup
13.8 Datum Setting with 3-D Touch Probe (Touch Probe Function
Software Option)
The "Corner as datum" probing cycle identifies the angle and
intersection of two straight lines. In addition to datum setting, the
cycle can also activate a basic rotation. The TNC has two soft keys
for you to decide which straight line you wish to use for this. The
soft key ROT 1 activates the angle of the first straight line as basic
rotation and the soft key ROT 2 the angle of the second straight
line.
If you wish to activate the basic rotation in the cycle, you must
always do this before datum setting. After you set a datum or write
to a zero point or preset table the ROT 1 and ROT 2 soft keys are
no longer displayed.
