This paper gives a review of the methodology used to tune the run-in process of a PC manufacturing line. It shows in some detail the analysis carried-out on the test data gathered on the manufacturing line and presents a clear picture of the run-in process in order to choose the best compromise between process efficiency and costs. 相似文献

Early failure analysis of machining centers: a case study 总被引:3,自引:0,他引:3
To eliminate the early failures and improve the reliability, nine ex-factory machining centers are traced under field conditions in workshops. Their early failure information throughout the ex-factory run-in test is collected. The field early failure database is constructed based on the collection of field early failure data and the codification of data. Early failure mode and effects analysis is performed to indicate the weak subsystem of a machining center or the troublemaker. The distribution of the time between early failures is analyzed and the optimal ex-factory run-in test time for machining center that may expose sufficiently the early failures and cost minimum is discussed. Suggestions how to arrange ex-factory run-in test and how to take actions to reduce early failures for machining center is proposed. 相似文献
