Metamorphic Manufacturing is the real-time combination of ICME, machine learning, robotics and forging. In this scenario, the robot manipulates the hot metal under a forging press. Sensor are continuously monitoring the temperature and geometry of the forging. The sensor data feeds the machine learning system which leverages ICME to adjust the thermal and strain profiles real-time while incrementally controlling the final part geometry.
This project compares and contrasts Computer Numerical Control (CNC) machining of wrought/billet material, additive manufacturing and metamorphic manufacturing in reference to their viability for creating replacement aerospace parts for applications that were originally designed as closed die forgings. Each of the three techniques were developed to maximize the performance and minimize the cost, without altering the geometric design of the original forged part. Each are evaluated in terms of cost, production time, microstructure, dimensional stability, hardness, and tensile strength.
