Electrical control design of CNC equipment fault based on part quality

Abstract

Aeronautical structure component has high value and complex shape, normally manufacturing by advanced five-axis CNC machine tools, but sometimes random failures also occur. Therefore, this research focuses on how to predict the failure, imply redundancy design technique and minimize part quality risk as much as possible. This article first analyses quality risk caused by device failure in manufacturing and introduces several axis movements during alarm occurring, then studies the influence of accuracy in movements and optimizes by the electrical and external power grid redundancy design. At last this article carries out engineering verification though practice application and reduces the quality risk from device failure in order to prepare quality insurance system in intelligent manufacturing.
