Simulation Analysis of Boring Finishing Process for a Thermal Power Unit's Valve Body

Abstract:

Control valve is the key element for a thermal power unit. As the core component of the valve assembly, the machining quality of valve bodys mating part is an important factor to restrict the performance of valve, so during the machining process, the demands for dimensional accuracy and surface quality of mating surface are quite high. Firstly, set the cutting tool, cutting parameters and other initial conditions according to enterprises actual requirements of body machining. The Deform 3D which is 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 deformation of boring cutter due to cutting force, temperature and abrasion under the condition of different cutting parameters, which influence the quality and precision of valve bodys machining surface. The analysis results obtained in this paper will provide reference for the choice of cutting parameters in the process of actual valve body finish machining.
