Paper Abstract

Calibration of machine tools refers to the process of determining the relation between output and the value of input quantity. It refers to the system of conformity testing based on metrological characteristics. Parametric calibration is the only comprehensive indicator which depicts a detailed picture regarding accuracy of machine tool. In this paper the most important parametric errors of coordinate measuring machines (CMMs) were calibrated through transfer standards and by implementing conventional methods and techniques, in the sense that modern sophisticated instrument like laser interferometers are expensive and beyond the economical range of small industries besides they need comprehensive training and strong background knowledge for error prediction and analysis. In this scenario it is imperative to develop and implement some easy to use and cost effective efficient methods by exploiting the available resources. The methodology was implemented on a three coordinate measuring machine as per standard procedures of error measurement under controlled environment. Obtained results were reported for its further use to compensate the parametric errors, either physically compensation or correction in the measurement results.
