The Oak Ridge Y-12 Plant produces large numbers of hemishell workpieces using precision computer-controlled lathes. In order to improve the quality/productivity of these machines, a pilot project is under way to demonstrate the utility of automatic, on-machine measurement of key workpiece features. This system utilizes tough-trigger probes and on automatic tool changer to generate data for a host data base that monitors and adjusts the machine's operations for variable machining conditions. This paper discusses the individual components, control software and data communications that are used to achieve an automated machining system which incorporates statistical process control.
