Abstract:

The RAPTECH-ACM program yielded the following research accomplishments 1 Development of process models governing heat transfer, consolidation, crystallization, intimate contact, healing, and residual stress and warpage. These models have been incorporated into a real-time neural-network-based simulation. 2 Incorporation of advanced model-based control on line and optimization to establish setpoints for heat input, velocity, and pressure to achieve the desired quality i.e., bonding, void content. 3 Integration of infrared sensors for feedback control. 4 Successful demonstration on lab-scale robotic workcell. 5 Transition of technology to industrial partners. 6 Mounting of DuPont Generation 3 head onto Cincinnati Milacrons gantry tape layer, where it is being used to make high-quality parts for HSR less than 1 void content, mechanical properties approaching autoclave baseline.
