Research On Milling Performance Of Fluorine Mica Glass And Ceramic

Fluorophlogite Ceramics is a new type of machinable glass-ceramic material,which is widely used in new energy,biomedical,optoelectronic communication,space technology and other industrial production and high-tech fields.because of its high hardness,high mechanical strength and high wear resistance,excellent chemical stability,thermal stabilityand precision instruments.But the fluorophlogopite ceramic machining efficiency is low,cost is high,tool wear fast,which limit the fluorophlogite ceramic material more widely used.In this paper,the TIALN coated carbide tool and the W18Cr4V high speed steel tool were used to the dry milling test on the fluorophlogopite ceramic sample.The cutting forceO,the surfaceroughness of the fluorormogresand tool wearwere analyzed systematically.which provides theoretical reference for the development of milling process of fluorophlogopite ceramic materials in actual production.The main contents of this paper are as follows:Firstly,the dry milling test of the fluorophlogopite ceramic material was carried out by two different milling cutters.The change of the milling force was measured by the kistler dynamometer.The surface roughness of the workpiece was measured by TR110 pocket roughness meter.The influence of milling parameters on cutting force and surface roughness was analyzed by single factor method.The effect of milling parameters on cutting force and surface roughness was discussed by orthogonal test,and the optimal milling scheme was obtained.The results showed that:thecutting performance of TIALN coated carbide cutting tools arebetter,which is more suitable for processing fluorophlogopite ceramic materialsSecondly,the prediction model of milling force and surface roughness of machiningfluorophlogopite ceramic materials was established by multiple linear regression analysis.The significance of regression equation was tested by MATLAB software.The results showed that:The TIALN coated carbide cutting tool prediction model can predict the milling and surface roughness effectively during the actual machiningFinally,the MV3020 two-dimensional optical imager was used to measure the wear amount of the tool flank during the cutting by two kinds of milling tools and studied The service life of the two kinds of dry milling mica ceramic materials.The S-4700 scanning electron microscopy was used to observedthe wear pattern of the tool's rake face and the flank face after the milling process,and the characteristic points of the wear area are analyzed by energy spectrum,and the wear mechanism of each cutting tool is analyzed.The results showed that:TIALNTIALN coated carbide cutting tools are best for dry milling of fluorophlogite ceramic materials.
