Programming example

Calibrate tool probe automatically, machine-related for G17
Values of the calibration tool T7 D1:
Tool type (DP1):
Length 1 - geometry (DP3).
Radius - geometry (DP6):
Values of tool probe 1 in block GUD6
before calibration:
_TP[0,0] = 50 (minus X axis)
_TP[0,1] = 28 (plus X axis)
_TP[0,2] = 42 (minus Y axis)
_TP[0,3] = 20 (plus Y axis)
_TP[0,4] = 80 (minus Z axis)
_TP[0,6] = 21 (cutting edge diameter on upper edge)
_TP[0,7] = 133 (can be calibrated: minus Z axis, in both X and Y directions)
_TP[0,8] = 101 (cutting edge in X/Y)
_TP[0,9] = 4 (distance to upper edge, depth of calibration)

Explanation of example
The tool probe is calibrated from the starting position in the –Z, +X, -X, +Y, -Y and again -Z
axes. The values are entered in the _TP field and _OVR field if the results (values of the
differences) are within the limits:
>_TZL, <_TSA.
