DIEGO, Núñez; BYRON, Núñez; HENRY, Vaca  e  MARITZA, Ureña. Influence of minimum quantity of lubricant MQL on tool life of carbide cutting tools during milling process of steel AISI 1018. Enfoque UTE [online]. 2017, vol.8, n.2, pp.44-55. ISSN 1390-6542.  https://doi.org/10.29019/enfoqueute.v8n2.157.

Nowadays, high productivity of machining is an important issue to obtain economic benefits in the industry. This purpose could be reached with high cutting velocity and feed rate. However, the inherently behavior produce high temperatures in the interface of couple cutting tool/workpiece. Many cutting fluids have been developed to control temperature in process and increase tool life. The objective of this paper is to compare the carbide milling tool wear using different systems cutting fluids: flood and minimum quantity of lubrication (MQL). The values of carbide milling cutting tool wear was evaluate according with the standard ISO 8688-1 1989. The experimental results showed that using MQL reduces significantly (about 40%) tool wear in milling AISI 1018 steel at industrial cutting conditions.
