Multi-criteria decision for machining process plan evaluation using fuzzy logic modeling and feature based method

Abstract

Machining is mostly used to transform raw material into a finished part before assembly to become benefit products and machinery. CAD/CAM is used to assist an engineer to create a part and tool part together with an NC code for a CNC machine. Process planning plays a key role in machining efficiency and optimization. This paper purposes a multi-criteria decision for machining process plan evaluation using fuzzy logic modeling and feature-based design representation with the condition of time, cost, tool life, precision, and surface. The results showed the alternative of the best machining process plan.
