Abstract:
Minimum quantity lubrication (MQL) is an established concept to meet high ecological and economical demands in metal machining. Compared to flood cooling, MQL massively reduces the efforts associated with the supply and disposal of the lubricants and the handling of emulsion contaminated chips. At the same time, MQL can reach a similar tool life. The mechanisms that have an influence on this effect are a matter of ongoing research. For this work, aerosol was generated by a 1-channel MQL system and supplied to a drilling process with AISI 4140 specimen. The drilling torque, feed force and workpiece temperatures are evaluated under different MQL air input pressures and tool cooling channel lengths. The results are interpreted by the help of flood cooling reference tests and high speed camera recordings, which reveal the open-jet atomisation of lubrication ligaments at the tool exit, arising from different MQL operation parameters.
