...Yi Xiong; Yunlong Tang; Sang-In Park; David W. Rosen Process plans in additive manufacturing (AM) have a profound impact on the performance of fabricated parts such as geometric accuracy and mechanical properties. Due to its layer-based, additive nature, AM processes can be controlled at multiple...

... algorithms process planning product design project management resource allocation Enterprises are increasingly faced with the challenges of satisfying diverse customer needs at low costs and with rapid response. Designing product families has been recognized as an effective means to meet...

... and subsequently supporting design process planning decisions. This paper applies timed colored Petri nets (TCPN) to model various elements of the product variant design process. The TCPN model performs as a generic design process platform from which alternative configurations of process plans can be derived...

... of prototype parts to match key characteristics of production parts, such as stress and deflection behaviors. For RP parts, the geometric tailoring DFM method integrates two sub-problems, one for achieving functional requirements by matching part behaviors, and one for RP process planning to incorporate...
