Abstract:CAK Series CAK3675V, produced by Shenyang No.1 Machine Tool, is a modern mechanical-electrical- liquid integration equipment which has diverse fault modes. According to all the possible failures which might happen on CAK3675V, the Failure Mode Effects Analysis and Fault Tree Analysis can be used to determine which is of relatively high failure frequency among design, manufacture, assembly and out-sourced parts. In the light of the reference data relating to machine tools as well as the discussion with the design and maintenance staff of the manufacturer, the improvement methods of CAK3675V's design, manufacture, assembly and outsourcing have been determined to ultimately enhance the reliability growth technique of CAK3675V.
Key words:CAK3675V CNC lathes;fault diagnosis;reliability growth technology
