Cycle definition for presetting in the touch probe axis
Touch point: X coordinate
Touch point: Y coordinate
Touch point: Z coordinate
Safety clearance in addition to SET_UP column
Height in the touch probe axis at which the probe can
traverse without collision
Write Z coordinate in line 1
Set touch-probe axis to 0
In the preset table PRESET.PR, save the calculated preset
referenced to the machine-based coordinate system (REF
system)
Center of the bolt hole circle: X coordinate
Center of the bolt hole circle: Y coordinate
Diameter of the bolt hole circle
Polar coordinate angle for 1st hole center
Polar coordinate angle for 2nd hole center
Polar coordinate angle for 3rd hole center
Coordinate in the touch probe axis in which the
measurement is made
Height in the touch probe axis at which the probe can
traverse without collision
Enter center of bolt hole circle (X and Y) in line 1
