Study on removal mechanism of steel bonded cemented carbide material GT35 in cutting process

  • 摘要: 为研究金刚石磨粒刀具切削钢结硬质合金GT35的微观刻划过程与材料去除机理,以单颗粒金刚石刻划实验为研究手段,分析其微观切削力的影响因素及材料的微观去除过程。通过单颗粒金刚石变切深实验发现,切削力与切痕截面积之间呈线性关系,获得的线性比例系数k的估计值可通过单颗粒金刚石等切深实验修正。随后,通过扫描电镜对GT35材料表面切痕形貌进行观测,并用激光共聚焦显微镜对其形貌进行三维建模,研究不同刻划深度下的材料去除模式。结果表明:修正后k(Fx)为0.026 29 N/μm2R1=0.990 46),k(Fz)为0.046 42 N/μm2R2=0.994 08); 调质GT35材料在多种切深下均以塑性去除为主,其中切痕底面呈现明显塑性剪切去除状态,切痕边缘位置呈现一定的脆性断裂状态。刀具在切削过程中会在刀尖处形成材料堆叠死区,引起刀具崩刃及磨损,且切痕表面形貌的形成与刀具磨损密切相关。
