Paper Abstract

A microprocessor-controlled measuring system model is described in this paper . This system which consists of a sliding guide with a linear motion slide plate a linear inductosyn the signal processing circuit and the microprocessor system can be used on some machine tools such as the lathe the milling machine the drilling machine etc. to take measurements of the absolute displacement of slide plates in process. In order to maintain the expectant accuracy in measurement over a long time it is necessary for the measuring system to be calibrated and corrected periodically . The mathematical models used to approximate the error curve are developed. By utilizing the computing ability of microprocessor the automatic calibration and correction for intelligent instruments can be realized conveniently and an expectant accuracy can be maintained in the period between two successive auto-calibrations.
