Progress in the research of reliability technology of machine tools

Abstract

The computer numerical control (CNC) machine tools are the important manufacturers of other equipment in equipment manufacturing industry and their reliability level has now become the bottleneck which restricts the industry development. A comprehensive review on the state of the reliability technology research is given. A comprehensive discussion is presented on the situation of the reliability technology of the CNC machine tools in China. And then the techniques of reliability modeling and the failure analysis are discussed as well as the design technique for CNC machine tools and then the characteristics of the field test. And then the bench tests in laboratory are analyzed for key functional parts of CNC machine tools. Based on the progress of machine tools reliability, the problems are stated and the prospective tasks of this field are proposed, simultaneously, the research hotspots and trends are illustrated. The development visions of machine tools reliability are speculated based on the own law and the industry demand of machine tools. © 2013 Journal of Mechanical Engineering.
