Nitrex Metal designed a process control system retrofitted to a vacuum furnace for Woodward Governor, Rockford, Ill. The two-part specification required the control system to (1) communicate with the company's central production scheduling and tracking software and to (2) reference a library of process recipes and match parts to its corresponding heat-treat cycle. To meet this goal, Nitrex configured the system software with added instrumentation and hardware to be compatible with the Woodward production system.
