This paper proposes a novel density-based method for structural design considering restrictions of multiaxis machining processes. A new mathematical formulation based on Heaviside function is presented to transform the design field into a geometry which can be manufactured by multi-axis machining process. The formulation is developed for 5-axis machining, which can be also applied to 2.5D milling restriction. The filter techniques are incorporated to effectively control the minimum size of void…

A new development of a shadow density filter for manufacturing constraint and its applications to multiphysics topology optimization

A new shadow density filter is developed and its usage for structural topology optimization (TO) considering the molding manufacturability and several numerical examples of compliance minimization problem, conjugate heat transfer problem and fluid-structure interaction problem are solved to demonstrate the validity and effectiveness of the present shadow density filters.

3D level-set topology optimization: a machining feature-based approach

This effort is an extension of level-set topology optimization into a domain of structural optimization for manufacturing (OFM) and the engineering information embedded in those feature primitives can be extracted and integrated into the optimization formulation.
