Optimizations are a powerful tool for engineers as well as product designers. Using optimization helps us to find out new concept designs that satisfy the requirements of functions, aestheticism, material, cost, and time. This paper gives an overview of structural optimization and its effects on the design process, provides the process and application of the topology optimization as well as its ability and importance in design to improve product and product design processes in general and CNC router in particular. Application of optimization methods includes topology, shape, and size optimization to design the structures of the CNC router. The results have built the optimization design process of CNC router structure, secured material reduction, as well as improved shape and size of CNC router structure. In the framework of this paper, the high applicability of structural optimization in the design of the CNC router structure will be properly introduced. Simulation for structural design and analysis has developed according to the strong and widespread application of computers and flexible application of CAD/CAID/CAE software in design has proven superior advantages compared to previous methods. The obtained results not only ensure the technical and aesthetic requirements of the design but also reduce the material.
