A special attention has been paid to the near-dry machining process from the view point of environmental protection. In the near-dry machining process, the very small amount of cutting oil is supplied to the cutting point with pressurized air flow. The purpose of this research is to analyze the tribological phenomenon at the cutting point under the near-dry machining processes. The research has been carried out for three years from 2002 to 2004. The results obtained through the research are summarized as follows.1)Cutting tests in the high vacuum chamber and under the near-dry cutting condition :In order to analyze the tribological phenomenon of near-dry cutting, a special type of cutting test system was designed and fabricated. The test system enables the cutting tests in high vacuum or selected gas. Using the developed cutting test system, the absorption of ester, oxygen and nitrogen on the pure metal surface was analyzed. The good cutting condition was obtained for the carbon steel … More due to the lubrication effects of the oxidation layer and absorption layer of ester. For the aluminum alloys, the supply of the nitrogen gas to the cutting point improves the machining performances.2)The relation between the basic tribological properties and practical cutting process :The polyester provides higher performance in lubrication comparing with the monoester. The influences of cutting oil on the machining performances coincides with the influences on the results of the wear test. The synthesis ester oil provides an excellent cutting performance at the very small amount of oil supply rate (less than 2-30ml/h).3)Feature tasks :The following points are suggested as feature tasks. (1)The detailed analysis of chemical reaction between the carrier gas and cutting oil. (2)The detailed analysis for the influences of synthesis ester oil structure on the cutting performances. (3)The investigation of the cutting performances using other than the synthesis ester oil. (4)Application of near-dry machining to difficult to machine materials. Less

从环境保护的角度出发，对近干式加工工艺给予了特别关注。在近干式加工过程中，极少量的切削油通过加压气流供应到切削点。摘要本研究旨在分析近干式切削加工过程中切削点的摩擦学现象。本研究从2002年至2004年进行了三年。主要研究成果如下：1）高真空室和准干切削条件下的切削试验：为了分析准干切削的摩擦学现象，设计并制作了一套特殊的切削试验系统。该测试系统可以在高真空或选定的气体中进行切割测试。利用研制的切削试验系统，分析了酯、氧和氮在纯金属表面的吸附情况。获得了较好的切削条件 ...更多信息 由于酯的氧化层和吸附层的润滑作用，对于铝合金，在切削点通入氮气可提高切削性能。2）基本摩擦学性能与实际切削过程的关系：聚酯的润滑性能优于单酯。切削油对切削性能的影响与对磨损试验结果的影响是一致的。合成酯油在供油量很小（小于2- 30 ml/h）的情况下，就能提供优异的切削性能。3）特征任务：建议将以下几点作为特征任务。（1）详细分析了载气与切削油之间的化学反应。（2）详细分析了合成酯油结构对切削性能的影响。（3）使用非合成酯油的切削性能的研究。（4）近干式加工在难加工材料中的应用。少
