[ 1 ] - A new approach to enhance final surface quality in drilling operation: evaluation of using alumina micro-particle additives on oil-water emulsion cutting fluid

Reaming is a common finishing process for improving the drilled holes surface quality. Choosing an appropriate finishing method in drilling process has a significant effect on the surface quality of holes and in decreasing the process total cost and time. In this study, four similar holes were drilled on the AISI 4340 workpiece with different two pair feed rates. The drilling process was perfor...
