Abstract

Optical inspection systems are readily available for the bench-top inspection of a variety of subjects including cutting tools. However, the integration of optical tool inspection techniques into precision machining operations requires the consideration of several factors. Some of the questions that must be answered include: What kinds of tools will be used? What tool characteristics are important to measure? How are these characteristics expressed in a meaningful form that will enhance the quality of the manufacturing process? What will be done with the tool inspection data? Will the inspection be performed on-line, in real-time, to what resolution and accuracy, etc.? This paper describes the integration of an on-machine optical tool inspection/compensation system (OTICS) to a precision turning machine at the Oak Ridge Y-12 Plant. OTICS is an IBM personal computer (PC) based system that uses a vision interface board to collect cutting tool form data. This information is used by the PC to prepare a compensated part program that avoids the workpiece errors that are associated with imperfect cutting tools. Machining tests have demonstrated the system's ability to produce workpiece contour accuracies of 0.0002 in. when using cutting tools with errors as large as 0.0046 in.
