Notes on various calibration methods

Rough optimization during commissioning after entering
approximate dimensions.
Number of measuring points between 1 and 2
Angular step of the rotary axes: Approx. 90°

Fine optimization over the entire range of traverse

Number of measuring points between 3 and 6
The start and end angles should cover the largest possible
traverse range of the rotary axes
Position the calibration sphere on the machine table so that on
rotary table axes there is a large measuring circle, or so that on
swivel head axes the measurement can be made at a
representative position (e.g. in the center of the traverse range).

Optimization of a specific rotary axis position

Number of measuring points between 2 and 3
The measurements are made near the rotary axis angle at which
the workpiece is to be machined
Position the calibration sphere on the machine table for calibration
at the position subsequently intended for machining

Inspecting the machine accuracy

Number of measuring points between 4 and 8
The start and end angles should cover the largest possible
traverse range of the rotary axes
Determination of the rotary axis backlash
Number of measuring points between 8 and 12
The start and end angles should cover the largest possible
traverse range of the rotary axes
