Abstract: A rapid process preparation and optimization system was developed to realize quick research and development of phased array radar. The hierarchical model, the functional analysis model, and the data transmission model of rapid process preparation and optimization system were established. Rapid design of process planning was realized by using a method combining case-based, knowledge- based and interactive Computer Aided Process Planning (CAPP). A method to achieve rapid fixture design was put forward based on case-based fixture design and complemented with interactive fixture design. The optimization subsystem for process parameter optimization was established by using process parameter database and knowledge base as the kernel. The neural network based optimization and physical simulation with finite element analysis were applied in subsystem. Implementation of the rapid process preparation and optimization system would improve the quality of manufacturing and shorten the development cycle.
