Ultrasonic sensors show great promise in defect detection and classification when monitoring the powder injection molding (PIM) manufacturing process. To date, however, these sensors are not used in a closed-loop control system. A simplex method is developed that automatically tunes a manufacturing system operating conditions on the basis of in situ ultrasonic sensor readings. Potential applications for this system include the initial set-up of optimal manufacturing conditions and also tracking of the optimum conditions in situ during long-term operation.
