Abstract

This paper seeks to explore the practical possibilities of developing a mechanical artifact that can be used to verify the accuracy and precision of a CNC machine tool. It is acknowledged that regular interim checks of machine tools ensure a high quality assurance within the manufacturing loop. The development of this artifact is biased towards volumetric and geometric calibration using stereometry as the mathematical foundation, and can be used on both vertical and horizontal machine tools. Introduction It was in the early part of the 20th century that the work in establishing acceptance standards for machine tools first began. Schlesinger [1] who commenced this work published a comprehensive set of acceptance test specifications in 1927. It was this work that became the foundation of future advancem
