【摘要】 对波形刃铣刀片切削时粘结的产生过程进行高速摄影。利用扫描电镜观察刀片破损形貌,发现刀片断口处材料严重剥落。对刀片破损断口进行能谱分析,证实刀片与粘屑相互粘结有对方材料元素。结合理论分析得出粘结破损受切削用量和工件材料的影响关系,为粘结破损判据及三维复杂槽型优化重构提供理论依据。更多还原

【Abstract】 The generation process of wave insert’s sticking failure is recorded t hrough high-speed photography. By scanning the damaged shape feature and using t he SEM, it seems that the material of the blade’s break area peels off seriously . According to the EDX analysis on the break area of blade, it’s found that the bits and blade glue the other side material elements of each. Based on theoretic al analysis, the author gets the relation of influencing between the sticking fa ilure and the cutting consumption, the work piece material, which provides the a cademic basis not only for the study of the sticking failure criterion, but also for the further optimization and reconstruction of milling insert with 3D compl ex groove.更多还原
