中文摘要:采用激光加工方法在硬质合金刀具前刀面易磨损区域加工椭圆状微织构,并在微织构中填充MoS2固体润滑剂,制备了微织构自润滑刀具。运用有限元方法分析了微织构对刀具刀尖处应力分布的影响;将微织构自润滑刀具与传统刀具进行了干切削45号钢的对比试验。结果表明:微织构的存在对刀尖处的应力分布无显著影响,与传统刀具相比,微织构自润滑刀具能够有效降低切削力和切削温度,减小切屑变形,增加切屑卷曲,同时减缓刀具前刀面磨损。

Abstract:Elliptical micro-textures were made by using laser on the rake face of the tungsten carbide cutting inserts. Molybdenum disulfide (MoS2) solid lubricants were embedded into the micro-textures to form self-lubricating textured tools. Finite element analysis was conducted to assess the effect of micro-texture on the stress distribution of the cutting inserts. Dry cutting tests were carried out with these self-lubricated cutting tools and conventional cemented carbide tools. As the results, there is no conspicuous adverse effect on the stress distribution of the tool nose with micro-textures on the rake face. The cutting forces and the cutting temperatures with the self-lubricating textured tools were greatly reduced compared with that of conventional cemented carbide tools. Meanwhile, the rake wear and the chip deformation were reduced, and the chip coiling was improved with micro texturing lubrication.

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.
