A Maintainability Prediction Method of NC Machine Tools Based on Comparing with the Benchmark Failure Mode

Abstract:

In order to overcome the problem that the maintenance date for NC machine parts was lacking, this paper proposed a maintainability prediction method based on comparing with basic unit. The biggest difference from traditional methods was that the traditional methods analyzed parts, but in this method, failure modes were analyzed and interval number was used to express expert opinions. The maintenance action for each failure mode was decomposed into several basic maintenance tasks. Comparatively speaking, the method had more adequate data and higher accuracy. Finally, the method was illustrated with an example. The analysis results showed that the method was feasible for the maintainability prediction of NC machine tools. It could solve the existing principal problems and provide a new idea for predicting maintenance in the field of NC machine tools.
