Unformatted text preview: 540:304 Manufacturing Processes Laboratory Spring 2011 Laboratory Report #4 Coordinate Measurement Machine (CMM) and Reverse Engineering by Farrah Vijayan Date 2/24/2011 I. Introduction : This lab required students to use CMM i.e. Coordinated Measurement Machine to measure 36 identical engineering tools. CMM can be manually controlled or computer controlled. There are in total three axes and measurements are determined by a probe attached to the third moving axis of the machine. Probes can be mechanical, optical, laser, or white light, etc. The diameters, the smaller diameter and the length of the shaft were measured. The readings were noted multiple times to get an accurate value for the shaft’s dimensions. Based on these dimensions the three dimensional drawing (Figure 2) is made. II. Experiment Description : The lab involved repetitive measurement of work pieces using CMM. The dimensions L,l,D,d were measured . The objective of the lab was to compare the measurement readings of this instruments by both the tools from previous lab with...
