刀具几何参数对钛合金铣削力和表面完整性的影响
Influence of Tool Geometrical Parameters on Milling Force and Surface Integrity in Milling Titanium Alloy
摘要
Abstract
With regard to the milling process of TC18,the effect of tool geometrical parameters on milling force and surface integrity were studied based on orthogonal experimental method.An empiri-to rake angle,clearance angle and helix angle were analyzed;the effects of tool geometrical parame-cal model of milling force was built;the absolute and relative sensitivities of milling force with respect show that the milling force is small in the case of big rake angle,small clearance angle and big helix ters on surface roughness and surface residual stress were investigated by Taguchi method.The results angle;the milling force is more sensitive to helix angle than clearance angle,least sensitive to rake an-gle;compressive residual stress can be detected on all the machined surface;the helix angle has signifi-cant effects on surface roughness,the clearance angle has significant effects on surface residual stress.关键词
