A surface-assisted machining method for reducing vibration of machining workpieces

Abstract

The invention provides a surface auxiliary machining method for reducing vibration of a machined workpiece. The surface auxiliary machining method comprises the following steps of 1, selecting a corresponding molding material and molding parameters according to a workpiece object needing to be machined and machining technological requirements, and mixing modified materials with the molding material; 2, analyzing the machining technology of the workpiece, creating adjustable auxiliary machining technological parameters so that molding equipment can be adjusted in real time according to the molding conditions in the molding process, and then, conducting rapid molding on the molding material on the surface of the workpiece through the molding equipment; and 3, finally, conducting machining. The method serves as the auxiliary machining technology adopted in the workpiece machining process; the technology is rapid and controllable; vibration generated in the workpiece machining process is reduced; machining precision is improved; surface quality of the workpiece is improved; the significant application value is achieved; and the method is particularly applicable to machining of the thin-walled workpiece with a complex cambered surface.

Description

technical field [0001] The invention belongs to the field of mechanical processing and manufacturing, and in particular relates to a surface auxiliary processing method for reducing the vibration of a mechanically processed workpiece. Background technique [0002] Digital manufacturing is widely used in aerospace, automobile, energy, rail transportation and many other fields. At present, the vibration generated by the force of the workpiece in the process of cutting, milling and other mechanical processing is a core restrictive factor that limits the rapid and high-precision development of the processing process. Vibration in the machining process, if it is light, will affect the accuracy of the machined surface and affect the processing efficiency; if it is severe, it will cause the workpiece to be scrapped or even damage the processing system. In order to avoid damage caused by vibration, many processing equipment often work under conditions lower than the design paramete...

Problems solved by technology

However, because the weight of the workpiece changes continuously during the process of being processed, the center of gravity moves, and the traditional method of fixing by fixtures cannot achieve continuous suppression of such dynamic changes.
