Improvement of Process Capability in a Multistep Machining Process

Abstract:

The work in this paper will present a developed methodology for process capability evaluation and improvement in a multistep machining process. In this methodology, a physical model is developed to describe the complex variation propagation process throughout all steps in a multistep machining process. Then building on this physical model, a process capability index evaluation method is derived. A capability improvement procedure is developed to prioritize process improvement efforts based on the sensitivity analysis of process parameters. Finally, the effectiveness of the proposed methodology is demonstrated in a case study.
