or appropriate ow rate, exclusion of leftover cutting uid would be a brainstorm-
ing issue during micromachining. Therefore, every machinist or engineer should
exceptionally take care of courses such as cooling, transporting chips, optimum
lubrication, and debris through micromachining. There were two dissimilar condi-
tions for lubrication related to edges, and surface quality was discussed. These were
MQL (minimum quantity lubrication) and dry lub
