Abstract
The use of a minimal quantity lubrication - MQL valve operating with lubricating oil and graphite for machining a Ti-6Al-4V alloy workpiece was the focus of this work. A comparison with different conditions was performed. The oil and oil + graphite conditions were studied The percentage of graphite for lubrication were established in 30%. A factorial design has followed a 23 model with two central points and one replica for each proportion used. The cutting speed, feed and cutting depth in a milling operation were defined as independent variables and the machining forces were measured with a rotating dynamometer and defined as dependent variables of the experimental planning used. Roughness measurements were performed After the tests. Statistical software was used to obtain the response surfaces. Some interactions were tested, and the feed rate were the variables that most influenced the roughness.
