针对硬质合金球头铣刀铣削钛合金TC17,研究了不同刀具结构参数对表面粗糙度、表面形貌、残余应力和微观组织的影响。结果表明:刀具参数选择前角 γ 0 =8°,后角 α 0 =12°,螺旋角 β=35°,可获得最好的表面完整性,表面粗糙度为 0.40µm,x 向残余压应力为 324MPa,y 向残余压应力为 218MPa,表层组织无明显变化。
Aiming at milling TC17 titanium alloy materials with carbide ball-end mill
effects of different ball-end cutter structural parameters on surface roughness
surface morphology
residual stress and micro-organizations are studied. The results show that when the rake γ 0=8°
fl ank α 0 =12° and helix angle β=35°
the best surface integrity for test pieces can be obtained. The surface roughness is about 0.40μm
the residual compressive stress in x direction is 324MPa
the residual compressive stress in y direction is 218MPa. And surface integrity doesn’t obriously change.
