Reliability assessment approach using failure mode analysis in machining center

The importance of evaluation and establishment during product development process, for the reliability and safety of mechanical system and parts, is getting increased in the field of mechanical and electronic industry. The object of this paper is to suggest the reliability assessment method for machine tools using failure mode analysis and to introduce two web-based analysis programs which save all data related to failure rate, failure mode, and failure component. In order to evaluate the reliability of machine tools, this paper takes three steps: the use of previous database, the failure rate estimation using failure history data, and the failure mode analysis using performance test.
