An intelligent fault diagnostic method based on data mining was presented to satisfy the development requirements of computer numerical control (CNC) machine tools'intelligence.
CNC machining is a manufacturing process in which a computer directs machines using programming codes to make a product. CNC (Computer Numerical Control) machining is a subtractive manufacturing process. This means that the computer program directs these tools (for example, drills, mills, and lathes) to constantly chip away at a workpiece.In order to solve the problem of health evaluation of CNC machine tools, an evaluation method based on grey clustering analysis and fuzzy comprehensive evaluation was proposed. The health status grade of in-service CNC machine tools was divided, and the performance indicator system of CNC machine tools was constructed.Milling is the machining process of using rotary cutters to remove material from a workpiece advancing (or feeding) in a direction at an angle with the axis of the tool. It covers a wide variety of different operations and machines, on scales from
