Abstract
A method for calibration of grinding and/or erosion machines assumes an initial calibration process and corresponding re-calibration processes. Calibration of the machine is performed with a reference piece and a reference tracer in an initial calibration process. Grinding tests follow the first tracing process from all directions during which tests deviations are determined and made ineffective with the iterative procedure. The machine-internal measuring system is calibrated immediately after performing the machining tests and thereby immediately after the initial referencing of the machining apparatus whereby the machine tracer and a test piece is traced from all coordinate directions and the resulting position values are stored. Subsequent re-calibrations supply measured values, which are compared to the stored values whereby correction values are determined then from the deviations for additional machining of workpieces.
