Abstract

The invention discloses a method and a device for improving the usability of a numerical control machine tool. The method includes: receiving statistical data related to faults of a numerical controlmachine tool and user requirements; using the data related to the faults of the numerical control machine tool to obtain an overall influence matrix according to the decision-making laboratory methodand transforming the overall influence matrix into an reachable matrix in the interpretative structural model, and establishing a multi-level hierarchical structure model; and establishing an availability requirement family of the numerical control machine tool, based on user needs and the multi-level hierarchical structure model, analyzing the availability requirement family, and establishing anavailability requirement hierarchy diagram of the numerical control machine tool. The invention integrates DEMATEL / ISM / QFD to improve the availability of the numerical control machine tool, more effectively and promptly improves the availability of the numerical control machine tool, and enables the availability requirement hierarchy of the numerically-controlled machine tool more intuitive to meet the requirements of users.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools, in particular to a method and device for improving the usability of numerical control machine tools. Background technique [0002] With the increasingly fierce competition in the global market and the increasing demand of users for the individualized performance of CNC machine tool products, the complexity of CNC machine tool products has become increasingly prominent. If there is a failure, it will cause heavy losses to the enterprise. It has become the key to improve the market competitiveness of my country's machine tool industry to keep the machine tool in the state of "usable when it is needed" and enhance its usability level. Therefore, it is extremely important to study the usability of CNC machine tools. [0003] The current research on usability improvement is mostly based on the results of failure analysis to find out the key failure modes. The research on usabi...
