An adaptive control optimization method for dynamic compensation of a metal cutting process

Abstract

The application relates to the technical field of machine tool control, in particular to an adaptive control optimization method for dynamic compensation of a metal cutting process, which comprises the following steps: acquiring initial tool path parameters, initial cutting parameter, tool geometric angle and workpiece material characteristics corresponding to a target metal cutting task; controlling the machine tool to perform a cutting operation according to the initial tool path parameters and the initial cutting parameter, collecting real-time vibration displacement of a tool-workpiece contact area and real-time load torque of a machine tool spindle motor in the cutting process; determining a current vibration state grade of the tool according to the real-time vibration displacement, querying a preset historical machining database according to the vibration state grade, and obtaining a target compensation curve matched with the current workpiece material characteristics. The application can reduce the risk of excessive wear by compensating the elastic deformation of the tool in real time and optimizing the cutting parameter according to the wear data, thereby prolonging the service life of the tool and reducing the production cost.
