Explanation of example
The calibration tool moves out of the starting position of N15 (X120, Z100) in Z to the center
of the probe with its "tool tip". An offset is applied to compensate for the calibration tool
radius. This places the radius center point in the center of the probe. The tool tip position is
shown: Z30 ((_TPW[0,0] + (_TPW[0,1]) / 2 -R = (50+20) / 2 -5=30)). This is followed by
traversal in measuring axis X (_MA=2, G18) to position X76 (_TPW[0,2] + _FA = 70 + 6 =
76). This is where actual calibration (like measurement) starts in the minus X direction. At the
end the calibration tool is again at position X76.
The new trigger values in minus X are stored in the data of tool probe 1 (_PRNUM=1)
_TP[0,2] if they deviate by more than 0.001 mm (_TZL=0.001) from the old values.
Deviations of up to 5 mm (_TSA=5) are permissible.
After that, the sides in the minus Z direction, plus X direction, and plus Z direction are
approached, calibrated, and the values entered in array _TPW[0,...].
