Abstract

Statistical process control is an excellent quality assurance tool to improve the quality of manufacture and ultimately scores on end-customer satisfaction. SPC uses PROCESS MONITORING CHARTS to record the KEY QUALITY CHARACTERISTICs (KQCs) of the component in manufacture. This paper elaborates on one such KQC of the manufacturing of a connecting rod of an internal combustion engine. Here the journey to attain the process potential capability index (Cp) and the process performance capability index (Cpk) values greater than 1.33 is elaborated by identifying the root cause through quality control tools like the CAUSE-AND-EFFECT DIAGRAM and examining each cause one after another. In this paper, the define-measure-analyze-improve-control (DMAIC) approach is employed. The definition phase starts with process mapping and identifying the KQC. The next phase is the measurement phase comprising the CAUSE-AND-EFFECT DIAGRAM and data collection of KQC measurements. Then follows the analysis phase where the process potential and performance capability indices are calculated, followed by the ANALYSIS OF VARIANCE (ANOVA) of the mean values. Finally, the PROCESS MONITORING CHARTS are used to control the process and prevent any deviations. By using this DMAIC approach, standard deviation is reduced from 0.48 to 0.048, the Cp values from 0.12 to 1.72, and the Cpk values from 0.12 to 1.37, respectively.
