The main objectives of this work are the study of the obtained surface roughness on steels, using face cutting edge inserts milling tools in finishing face milling operations with microlubrication (MQL), and comparison of the results obtained with the widely-used radius inserts. This experimental study analyzes the roughness and surface appearance obtained with both sort of inserts. The interest about this study is to determine the steel types and the optimal cutting conditions for milling with this face cutting edge inserts. Another result analysed is the utility of the MQL implementation compared to the dry system.
