PROCESS CAPABILITY ANALYSIS: AN EFFECTIVE TOOL FOR ASSESSMENT OF YARN MANUFACTURING PROCESS (Pages : 15 - 20)

Continuous improvement of a process is the prime focus for management and process capability analysis indices which are an effectual instrument for that. The application of process capability analysis as an effective tool of SPC was carried out for 3 different cases in carded hosiery yarn manufacturing. The actual data distributions of the carded hosiery yarn were checked and analyzed for determination of the process capability. The process capability analysis provide the process capability indices Cp, Cpu, Cpl & Cpk which indicate the stability of the process. Here three different cases were studied for same parameters such as Ne, CVcb%, CSP and IPI. The study showed the process capability indices for all parameters for the three examined cases. As an outcome of the study it was found that for all cases the process means were deviated from the target means which indicated that the process mean is needed to shift to the target mean by taking necessary measures or redefining the specification limits if necessary to make the process capable.Download
