Introduction
Equipment
Minimum Quantity Lubrication allows to
reduce the machining cost while keeping the
surface finish as good as possible. The
comparison between MQL methods using
different pulverizing devices and cutting
fluids has already been done. The objective
of this study is to highlight the influence of
the alloys during MQL turning of AA2024T351 and AA7075-T6 aluminum alloys. The
machinability indexes are the roughness, the
chip thickness and the tool wear.
Conventional VS Numerical Lathe
The use of a numerical lathe has been
demonstrated. It clearly generates
more accurate results.
The experiments had been
perform using a numerical
Lathe (MAZAK Nexus 100 II
M). The pulverizing device
(designed by Tecnolub) is
made by a pressurized tank
spouting a continuous flow
rate. A Sc
