Abstract
This paper presents an adjustment technique on controller setting values in CNC machine tools by measurement of servo induced feed drive errors. At high feed rate operations of CNC machine tools, servo induced errors are usually dominant and large compared with geometric errors. For measurement of the servo induced errors, an experimental equipment which incorporates two linear displacement sensors and a steel cube was developed, and servo feed drive errors were evaluated along a square corner test path. Based on evaluations of servo feed drive errors with different combination of parameters in machine control system, optimum setting parameters were found. The measuring equipment and optimisation method are described.
