摘　　要：大直径钛合金无缝管属于大型薄壁件,目前主要采用车削进行外圆加工,较大的径向切削力容易引起工件变形。正交车铣加工外圆表面时径向切削力相对较小,是一种能更好加工这类零件的新方法。通过三因素三水平正交仿真试验,研究采用偏心正交车铣加工大直径钛合金无缝管外圆时,切削参数对径向切削力的影响,建立了径向切削力的经验公式。结果表明,切削参数对径向切削力影响的大小顺序为a_(p)>f_(z)>v_(c),可通过适当增加每齿进给量提高切削加工的效率。Large-diameter titanium alloy seamless tube is a large-scale thin-walled part,which is mainly used for external processing by turning,and the large radial cutting force is easy to cause the deformation of the workpiece.Orthogonal turn-milling has a relatively small radial cutting force on machining the outer surface,which is a new method that can better machine this type of part.Through the three-factor and three-level orthogonal simulation experiments,the influence of cutting parameters on the radial cutting force of machining large-diameter titanium alloy seamless tube is studied by eccentric orthogonal turnmilling,established an empirical formula for radial cutting force.The results show that the influence of cutting parameters on the radial cutting force is in the order of a_p>f_z>v_c,and the efficiency of cutting can be improved by appropriately increasing the feed per tooth.
