Calibration of CNC Metal Cutting Machine Tools

INTRODUCTION

Machine Tool Calibration is rapidly becoming an essential part of the manufacturing process with customers demanding higher accuracy from machine tools for handling precision parts with tighter tolerances. The ability of a machine tool to perform at its optimum level is largely based on the geometrical and positioning accuracies of the machine slides and guideways. Machine tools are subject to positioning errors which might increase over a period of time due to natural wear and tear or failing parts or worn out moving parts.
