Abstract


Ti6Al4V titanium alloy with high strength, heat resistance and corrosion resistance and good properties, is widely used in the aerospace industry, but because of its low thermal conductivity, high chemical activity, elastic modulus and other small features make it a typical difficult materials processing tool wear caused serious damage, low productivity, poor surface quality, high production cost manufacturing process problems. In this paper, high-speed milling titanium alloy Ti6Al4V for the study, high-speed milling Ti6Al4V by studying the process of cutting force, cutting temperature, surface integrity, based on a comprehensive analysis of the carbide high-speed milling tool wear during Ti6Al4V, damage mechanisms and tool life and tool wear were studied after the effect of processing. A high-speed milling Ti6Al4V Experimental study of cutting force. Respectively, the use of indexable cutters and solid carbide cutting tools for high-speed milling Ti6Al4V single factor test and orthogonal experiment, the experimental results were very poor analysis, analysis of various factors on the cutting force of the cutting, the use of linear regression Methods milling force established empirical formula, and studied with the tool wear on the cutting force size. 2 high-speed milling tool wear mechanism of Ti6Al4V and Tool Life. Use of indexable milling in different cooling conditions of the tool wear test, the establishment of tool life empirical formula, using scanning electron microscopy and spectroscopy analysis tool wear patterns are analyzed and discussed during a high-speed milling titanium Tool wear mechanism; analyze different cooling environment on tool wear, and found that the coating can improve tool life, tool life different cooling a greater impact on the environment. 3 high-speed milling tool wear on Ti6Al4V surface integrity and chip morphology. The tool life test on the basis of studies with the tool wear on surface integrity and chip morphology were investigated for different cutting speeds indexable milling cutter and the overall impact on the surface roughness were analyzed. Studies show that when the tool after tool wear structure and properties change significantly influential on the cutting force and cutting temperature, resulting in a chip on the surface quality and morphology changes. 4 high-speed milling Ti6Al4V cutting stability analysis. Through theoretical method to analyze the process of cutting tool and the workpiece shape of the reason for the error, the establishment of milling chatter model; through experimental analysis of different structural mill processing flutter strength, machinability were compared; analysis of cutting parameters on the cutting chatter.
