Abstract
ABSTRACTAs a popular and effective tool for structural design, topology optimization has been increasingly used for mechanical part design in recent years. However, the effectiveness of topology optimization in mechanical design has been seriously affected by the poor manufacturability of parts generated. In this study, manufacturability in the topology optimization process is described by using the concept of a visibility map. Apart from additive manufacturing, almost all manufacturing processes can be associated with a visibility map. A part generated by topology optimization must conform to the visibility map of a manufacturing process thus generating optimized design that is manufacturable by the proposed manufacturing process. Since the visibility map concept can be used to describe most manufacturing processes, the proposed approach can be used as a general method for all mechanical part design when topology optimization is needed.
