MANUFACTURING COMPLEXITY EVALUATION FOR ADDITIVE AND SUBTRACTIVE PROCESSES: APPLICATION TO HYBRID MODULAR TOOLING

摘要

The aim of this work is to determine how to combine a subtractive process (HSM) and anrnadditive process (SLS) to realize tools (dies or molds). In fact, the design and manufacturingrnof tools may be optimized with hybrid and modular points of view. Tools are not seen asrnsingle pieces but as 3-D puzzles with modules; each module is manufactured by the bestrnprocess. So a new methodology is proposed: the most complex-to-manufacture areas of a toolrnare determined (based on a manufacturability analysis from tool CAD model) and a hybridrnmodular tool CAD model with a reduced manufacturing complexity is proposed.
