A review and analysis of energetic sustainability of cooling/lubrication technologies for small and deep hole drilling operations

摘要

The selection of the most suitable cooling/lubrication technology to reduce the severity of machining processes represents an important issue in machining.In addition,an improvement of cooling/lubrication condition may also have a sustainability impact in terms of resource efficiency,energy consumption,environmental and human impacts,as well as waste production.In this review paper,environmentally-benign alternatives to the traditional flood coolant application and their effects on the overall machining performance(i.e.,drill-wear,drill-life,hole quality,etc.),have been explored for the case of small and deep hole drilling.At the end,some suggestions for future research direction have been provided.
