中文摘要:现有端铣切削力模型是针对平头铣刀建立的,忽略了刀具几何外形对切削力系数及动态切削力的影响。通过对R刀几何外形分析,沿切削刃将铣刀进行离散化处理,对切削刃微元施用瞬时刚性力模型,通过坐标变换和数值积分获得R刀的动态切削力模型,推导出其切削力系数实验辨识公式。为验证模型的正确性,设计了仿真程序和切削实验,仿真和切削实验结果的一致证实了模型的正确性。

Abstract:

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
