Optimization Research On NC Machining Process Based On Lean Products

In recent years, electric-technology, computer technology and auto-technology have been greatly developed and widely applied in mechanical industry, which makes the wide usage of NC equipment. At the same time, how to improve the usage value of NC equipment and how to improve the production rate become the key point which enterprise should take into consideration. On such basis, the lean products has been proposed and also applied in mechanical industry. This article then provides the application research on NC machining process with lean products under such condition.During the NC machining process, the article, based on the lean products, combs and optimizes the key factors engaged in process for improving the NC equipment total efficiency. On the analysis on factory present condition, it makes application research on NC technology layout optimization, NC technology optimization, tolls usage solution optimization, NC program and transmission management and NC equipment management.In the process of NC technology layout optimization, based on the model products technology requirements, the key point is put on the flow production and cut-down the period of products turnover. In the process of NC technology optimization, the key point is put on the details of technology regulation and fine analysis on working procedure management and technology parameters. In the process of tools machining solutions, the key point is put on the NC tools usage management to cut the tools waste. In the process of NC program and transmission management, the key point is put on the discussion and research on the NC program standardization and transmission regulation. Meanwhile, the main content is put on the NC equipment management during the NC machining.Finally, the experiments have been carried out on certain model products during its NC machining process. It is proved that with the advancement of mechanical manufacture technology, it is necessary to execute the system optimization during the NC machining process so as to cut down the manufacture cost and improve the total efficiency of NC equipment.
