Dry high-speed machining: a cost effective and green process

Dry machining and Minimum Quantity Lubrication (MQL) machining are two emerging technologies that can help metal cutting industries produce desired parts at lower costs while reducing the negative effects of the lubricant on environment and on machine-tool operator’s health. The introduction of these technologies into the industry has been however very slow. In order to accelerate the introduction of this new technology into the industries, there is a need to develop environmentally-friendly machining strategies that are also cost effective. This work presents the needs and the requirements of dry machining and its effect on productivity, part quality and metallic particles generation. Some strategies for limiting the particles generation while maintaining a competitive level of productivity are also presented.
