Abstract

The invention provides a method for jointly optimizing tool geometry parameters and machining process parameters. The method comprises the steps that structural parameters of a tool, machining processparameters and respective ranges of values are determined; the orthogonal test of the machining process parameters and the orthogonal test of the structural parameters of the tool are constructed inrespective ranges of values; a cutting force model and a cutting temperature model are acquired according to the cutting force data and cutting temperature data acquired by two orthogonal tests; according to the cutting force model and the cutting temperature model, the optimization objective function of the geometry structural parameters of the tool is constructed; according to a machining targetto be optimized, the machining process parameters to be optimized are determined, and the optimization objective function of the machining process parameter is constructed; and according to the abovetwo optimization objective functions, a common optimization model is constructed, and the optimal solution is acquired to acquire corresponding values of the optimized tool structural parameters andmachining process parameters. According to the invention, each machining target in the actual machining process is comprehensively considered, and the optimal tool structural parameters and machiningprocess parameters are acquired.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for co-optimizing tool geometry parameters and processing technology parameters. Background technique [0002] The parameter design of the tool structure is very important to give full play to the performance advantages of the tool material. A good tool structure can improve the processing efficiency several times. Similarly, whether the cutting process parameters are reasonable or not is directly related to the processing efficiency and production cost, and also has a decisive impact on the processing quality of the workpiece. [0003] At present, there are many studies on the optimization of tool structure parameters and processing technology parameters. The more representative ones are Ding Guo, Jin Yanming, Liu Peijie, Yu Lang, "Test and Modeling of Forming and Milling Force of U71Mn Rail", "Tool Technology" , 2018, No. 11, pp. 32-38; Another example, ...
