A first approach to choose between HSM, EDM and DMLS processes in hybrid rapid tooling

Purpose – To propose a method to manufacture a hybrid rapid tool (a multi component tool).Design/methodology/approach – The part is decomposed into multi component prototype instead of a part made from a single piece. First, this method is based on a topological analysis of the tool. Features are regrouped starting from the numerical definition of the die. Second, the manufacturing possibilities of the high speed milling (HSM), direct metal laser sintering (DMLS) and electro discharge machining (EDM) process are analyzed. Finally this information is synthesized to obtain solutions. This method is validated by industrial example.Findings – A method is proposed to choose the best manufacturing process in order to optimize the manufacture of a “hybrid rapid tooling” between three processes: HSM, DMLS and EDM. So, it is possible to obtain the different components of the hybrid rapid tooling according to the envisaged process.Research limitations/implications – The final goal is to propose a software assistant...
