Abstract

A three line calibration method for error quantification in a prismatic joint of a machine tool was proposed and implemented by using a laser interferometer as a working standard. It greatly simplified the measurement setup requirements and accelerated the calibration of prismatic joints. Moreover, it was highly economical by reducing the calibration time and eliminating the use of complex optics. The methodology was implemented on prismatic joints of a three axis CNC machine tool as per standard procedures and guide lines. Cubic spline technique was implemented as error modeling and results obtained were reported for its further use to compensate the errors for improving the accuracy in prismatic joints.
