Investigating optimal parameters of abrasive water jet cutting process: engineering robust design based approach

摘要

The machining parameters with existing machining facilities are important for small and medium scale manufacturing firms as they run with tight profit margins. In this context, it is vital to investigate the effectiveness of the currently available statistical approaches for regular applications. This manuscript uses engineering robust design (ERD) approach for investigating the optimal abrasive water jet metal cutting parameters for existing machinery. First, the manuscript illustrates a mathematical framework which is possible to utilize for regular metal cutting applications. Secondly, it utilizes the mathematical framework for turning the machining parameters. Experimentation has been performed to establish the initial machining parameters via expert knowledge based levels. Optimal parameter have been calculated based on the experimental results. Then, the theoretical value of metal cutting output quality parameter has been calculated. Finally, a verification experiment has been performed to investigate the consistency of the experimentally observed machining parameters. Experimental and verification results have been reported.
