Center of circle: X coordinate
Center of circle: Y coordinate
Circle diameter
Polar coordinate angle for 1st touch point
Stepping angle for calculating the starting points 2 to 4
Coordinate in the touch probe axis in which the measurement is
made
Safety clearance in addition to SET_UP column
Height in the touch probe axis at which the probe can traverse
without collision
Do not move to clearance height between measuring points
Set display
Set the display in X to 0
Set the display in Y to 10
Without function, since display is to be set
Also set datum in the touch probe axis
X coordinate of touch point
Y coordinate of touch point
Z coordinate of touch point
Set the display in Z to 0
Measure circle with 4 probes
Move on circular path between measuring points
