【摘要】 本文来源于黑龙江省重大科技攻关项目:“大型、复杂零部件用现代刀具系列产品化与开发研究”课题中的一个子项。以研究波形刃铣刀片的切入类型的理论分析及其开发研究为主要内容。本文在总结M.Kronenberg接触法和林树兴的解析计算法基础上,推导了前刀面方程及其运动方程、主切削刃旋转所形成的曲面方程、前刀面运动时与工件切入侧面的接触线LM方程以及切削表面与工件侧表面交线C1D1方程,最后推导了八种切入类型判别式,上述成果为将来进一步研究三维复杂槽型铣刀片的切入破损打下理论基础。本文对不同切入类型的波形刃铣刀片的切削力进行了比较试验,同时用功率谱分析对波形刃不同切入类型的波形刃铣刀片进行了动态铣削波形的特性分析,从而进行切入类型的优选。本文对采用不同材质、槽型的波形刃铣刀片切削不同工件材料进行切削力对比试验研究。采用超细晶粒材质铣刀片和4030、4040切削45号钢和不锈钢进行切削力对比试验研究;并在电机厂对上述刀片进行寿命对比试验研究。最后,本文对车铣两用圆刀片的切屑形成、卷曲、流向机理进行了初步的研究。更多还原

【Abstract】 This is the sub-subject“The modern cutters on large and complex part are series manufactured and researched”of Heilongjiang province great science and technology tackle key problem item, which is mainly about the study of face milling cutter cut-in type.Based on summarizing the contact method of M.Kronenberg and the parse calculation method of Shuxing Lin, this thesis concluded the equation of the face and its movement equation, the curved surface equation produced by main cutting edge circumgyratting, the equation of the contact line LM produced when the face cutting-in the side face of the workpiece and the equation of the intersectant line C1D1 produced by the cutting surface and the workpiece side face, at last, the discriminant of the eight cutting-in manner were concluded, All the production above are the theory foundation for further researching the cutting-in disrepair of the 3-D complex groove insert..This thesis contrasted the cutting force of the wave-edge with different cutting-in manner, synchronously, the wave characteristic of the dynamic milling was analysed used the power spectrum analysis for wave-edge insert with different cutting-in manner and optimized choosing the cut-in type consequently.This thesis researched the cutting force contrast when cutting the work pieces made of different material used wave-edge insert made of different material. experimented and contrasted the cutting force produced by cutting the 45 steel and the stainless steel used the Ultra-fine grain insert ,4030 insert, and 4050 insert, and experimented and contrasted the life-span for the inserts introduced above in HEC. Finally, the thesis primary research the mechanism of chip’s forming, curling and flowing direction used the round insert which can be used in milling and turning.更多还原
