Process Capability Optimization in Multistage Manufacturing Processes Based on the Cost-Utility Ratio
نویسنده
چکیده
To solve the problem that process capability optimization in multistage manufacturing processes has not been studied so much. Firstly, a multistage manufacturing process quality variation model is built to analyze the impaction of each stage quality on process capability. Then, a multistage manufacturing process capability analysis method with “Costutility ratio” is proposed to prioritize process capability optimization efforts. At last, a two stage matching process is taken as an example to demonstrate it. The results show that this method ascertains the priorities and process capability optimization degree well.

متن کاملResiduals based process capability indices for two-stage processes
The manufacturing operations often involve multistage processes where the process capability of each stage is affected by the process capability of its precedent processes. This property is known as the cascade property. The purpose of this paper is to estimate the process capability of the second stage of two-stage process while the cascade property impact is removed using residuals analysis. ...

متن کاملIntelligent Knowledge Based System Approach for Optimization of Design and Manufacturing Process for Wire-Electrical Discharge Machining
Wire electrical discharge machining (WEDM) is a method to cut conductive materials with a thin electrode that follows a programmed path. The electrode is a thin wire. Typical diameters range from .004" - .012" (.10mm - .30mm) although smaller and larger diameters are available. WEDM is a thermal machining process capable of accurately machining parts with varying hardness or complex shapes. WED...
