Abstract

The advantages of standardization and modularization for manufacturing-friendly design are widely acknowledged. In design assessment, numerical evaluation forms are commonly used to evaluate both manufacturability and assembility. This article combines these two perspectives and proposes a tool enabling the evaluation and comparison of alternative constructions based on modularity, standardization, manufacturability and assembility.

The first part introduces a DFMA-evaluation ma-trix which considers an assembly’s suitability for modular-ization or standardization. The second part is preliminary validation of the results which includes accuracy meas-urements from the selected fixturing system.

The evaluation matrix proves to be a working evaluation method for evaluating levels of modularity and standardization.
