Topology optimization is used in the initial stage of the product manufacturing process. However, the non-manufacturable or non-machineable results of topology optimization have become an obstacle to process manufacturing. This paper proposes a modified topology optimization method by adding manufacturing and machining constraints to the topology optimization formulation. A hybrid topology optimization algorithm (combining the method of moving asymptotes and wavelets) is applied to solve this optimization problem. With this approach, the design space can be reduced and an engineering-accepted and manufacturable topology result can be guaranteed.
