Clean Cutting with Oil-fog

环境意识制造已经引起了许多制造工程师的兴趣。其目的是开发技术，以减少能源消耗以及制造过程中的排放。本研究的目的是开发实用技术，以满足减少切削过程中切削液供应的要求。通过本研究获得的主要结果如下：1.在铣削和钻孔中的切削液供应量可以成功地降低到50 ml/h。研制了能产生直径约为1 μm的油雾的油雾发生器.开发了可用于现有加工中心的油雾供应工具系统。该系统能够进行各种铣削操作。研制了具有高生物降解性的合成酯切削油。进一步提高了切削油的性能，使其可用于深孔加工.从刀具寿命、表面质量和切削力三个方面对整个系统的性能进行了评价.通过这项研究，大部分初步目标都可以实现。但指出，要弄清这种极少量切削液的润滑机理，还需要进行更多的基础研究。

Environment conscious manufacturing has attracted a lot of interests of manufacturing engineers. The aim is to develop the technology for reducing the energy consumption as well as the emission from the manufacturing processes. The target of this research is to develop the practical technology to meet the requirement of reducing the cutting fluids supply in the cutting processes. The results obtained through the study are summarized as follows :1. The amount of cutting fluid supply in milling and drilling could be successfully decreased down to 50 ml/h.2. The oil-fog generator that can generate the oil-fog of around 1 μm in diameter was developed.3. The tooling system for supplying the oil-fog that can be used for the pre-existing machining center was developed. The system is capable of various milling operations.4. Cutting oil based on the synthetic ester that has high bio-degradability was developed. The performance of the cutting oil was further improved so that it can be used for deep hole drilling.5. The performance of the total system was evaluated in terms of the tool life, surface quality and cutting forces.6. Most of the initial aims could be achieved through this research. However, it was pointed out that more fundamental research was needed for making clear the lubricating mechanism with such extremely small amount of cutting fluids.
