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 calibrating ball 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 ball 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
„ Determining the rotary axis backlash during inspection
„ Number of measuring points between 8 and 12
„ The start and end angles should cover the largest possible
traverse range of the rotary axes
