摘要
In order to accurately analyze the availability of CNC machine tools, a analyzing method for the availability of CNC machine tools was proposed based on meta-action theory.Firstly, the function-motion-action structural decomposition tree was used to decompose the mechanical system, and the basic meta-action and meta-action chain were obtained.And a steady-state availability model was established based on the faults and maintenance data of the constituent components of the meta-action unit.Then, a steady-state availability analysis model for the meta-action chain was established based on Markov process.Finally, a steady-state availability model of the whole machine system was established based on the formation processes of the whole machine system function.Taking the availability analysis of CNC grinding machines as an example, and the proposed method was explained. © 2023 China Mechanical Engineering Magazine Office.
