With the rapid development of China's aerospace industry and the increasing number of tasks year by year, the traditional processing methods have been unable to meet the needs of aerospace products with multiple varieties and small batches. It is urgent to find a low-cost and efficient production method. In view of this situation, this paper puts forward a design idea of an intelligent machining unit for aerospace electronics structural parts. Centering on improving equipment startup rate, reducing personnel demand, and improving quality consistency. Following the overall idea of "unified the type of processing method, complete some work offline, improve the flexibility of machining and intelligent decision-making", taking the built intelligent FMC (Flexible Manufacturing Cell) as an example, it realizes continuous and unattended automatic processing of products, Under the premise of ensuring quality, the production efficiency has been improved and good practical results have been achieved.
Selected Laser Melting (SLM) has the advantage of high flexibility and can realize near net shape of high-precision complex components, which provides a new technological way to design and manufacture metal parts. To apply the advantages of SLM more widely in the design and forming of aerospace components, taking one connecting part of the recovery subsystem as an example, it realizes the structural optimization design based on SLM, carries out the mechanical simulation analysis, and completes the forming and processing. The results show that on the premise of meeting the application requirements, the weight of the optimized parts can be reduced by 24.54% and the overall manufacturing cycle can be saved by 41.46%, which provides an effective reference example for the process optimization design of the similar aerospace structural parts formed by selected laser melting technology.
