Abstract

“On-Machine Inspection and Acceptance (OMIA) is a process that integrates the design, machining, inspection, and acceptance aspects of manufacturing to allow a product to be inspected and accepted on the machine tool. In this thesis, CNC controls, hardware/software requirements, development, installation and calibration of a probing system on a Cincinnati Milacron® Sabre 750 Vertical Machining Center (VMC) with Acramatic® 2100E CNC Control are presented along with the strategies, techniques and implementation of On-Machine probing on the Cincinnati Milacron® Sabre 750 VMC. Many issues affecting On-Machine probing are discussed including: Computer Architecture, Open architecture CNC controllers, data acquisition, types of touch-trigger probes, etc., Two strategies of On-Machine probing: In-Process On-Machine Probing versus Post-Process On-Machine Probing, and two techniques of probing: Single hit versus double hit techniques are also investigated. The results obtained from using these two strategies and techniques are compared with those obtained using the conventional Coordinate Measuring Machine (CMM). Renishaw® model MP10 Surface Sensing Probe was used for probing the machined dimensions. Renishaw® model TS27R Tool Setting Probe was used for setting the tool lengths. Brown & Sharpe MicroVal® CMM equipped with a Renishaw® MH8 Touch-trigger probe was used for CMM probing. It was found that On-Machine probing was better than CMM probing in every aspect including Setup, Tool-setting, Part identification, Un-manned machining with integration of Inspection and Quality control. Double hit technique of probing was found to be more reliable and more accurate as compared to the Single hit technique”--Abstract, page iv.
