The principle and the calibration method of the quadrant sensor are described. The laser diode with the built-in battery is employed with the quadrant sensor for the application of the spindle accuracy test without limitation of test runs. With this method, no error separation technique for the spindle accuracy is needed.CalibrationMachine toolsMeasurement errorsNumerical control systemsOptical sensorsSemiconductor lasersError separationQuadrant sensorSpindle accuracyPrecision engineeringconference paper2-s2.0-0141427706
