Experimental Study on Influence of Lubrication Conditions on TC4 Titanium Alloy Cutting Process
In order to study the influence of cooling lubrication conditions and cutting parameters on the cutting force and surface roughness of TC4 titanium alloy cutting process,the high-speed cutting experiments of TC4 titanium alloy under different cooling lubrication conditions and coarse,semi-refined and finishing experiments of four different lubrication condi-tions and cutting orthogonal experiments under CMQL are carried out respectively.The influence of cooling lubrication con-ditions and cutting parameters on machining is studied by univariate analysis and orthogonal analysis method.The research shows that the CMQL cooling and lubrication conditions can effectively reduce the cutting resistance and improve the sur-face roughness in the TC4 titanium alloy high-speed cutting,and it only shows the advantage of reducing the cutting resist-ance for the high-speed finishing cutting stage.Considering the processing efficiency of TC4 titanium alloy under CMQL condition,the best parameter combination is high cutting speed,small finishing allowance and large feed amount within the appropriate range.
