摘　　要：阀体关键部位的加工质量是制约阀门使用性能的重要因素,因此,在阀体加工过程中,对其配合面和密封面的尺寸精度和表面质量要求较高。利用金属切削工艺有限元分析软件AdvantEdge对阀体配合部位镗削精加工过程进行仿真,能够有效的模拟切削过程中刀具所受切削力和切削温度随时间的变化。并在此基础上结合单因素法,分析了不同切削参数条件下刀具所受力、受热变形对阀体被加工表面质量和精度的影响。分析结果为实际阀体关键部位精加工切削用量的选择提供参考。Machining quality of the key parts of value body is the important factor to restrict the performance of the valve, so during the machining process, the demands for dimensional accuracy and surface quality requirements of mating surface and sealing surface are quite high. Firstly, the AdvantEdge which is a metal cutting finite element software was used to simulate the boring finishing process of mating surface of the valve body, can effectively analyze the changing rule of cutting force and cutting temperature with time. Then, the single factor analysis method was used to analyze the influence of boring cutter due to cutting force and cutting temperature under the condition of different cutting parameters, which is exerted on machining quality and precision by the deformation. The analysis results obtained in this paper will provide reference for the choice of cutting parameters in the actual valve body finish machining process.
