| Summary: | In this research, the workpiece material used is AISI316L stainless steel,
which has higher corrosion resistance and is also difficult to machine at high speeds.
The objective of this study is to determine the machining performance of 316L
stainless steel using minimum quantity lubrication (MQL) and dry machining. The
effects of MQL lubricants and dry machining are then studied and compared in
terms of cutting performance, such as tool chip contact length, chip thickness, and
cutting force (N). The MQL lubricants used are a bio-lubricant: Crude Tamanu
Oil (CTO), Crude Jatropha Oil (CJO), Synthetic Ester (SE) and Refined Bleached
and Deodorized Palm Olein (RBDPO). The cutting insert used in this study is an
uncoated tungsten-carbide insert (WC) SPGN120308 to ensure that the surface of
the carbide insert is in direct contact with the stainless-steel disc. The cutting and
MQL parameters are set to be the same for both MQL and dry machining. After
machining, the micrographic representations of the chip and inserts are magnified
by examination with a scanning electron microscope using energy dispersive X-ray
spectroscopy (SEM–EDX) to identify any material adhering to the rake face of the
tool. It is found that SE gives the best machining performance compared to the CTO,
CJO, RBDPO and dry machining. Nevertheless, CTO and other crude vegetable oils
are exhibiting high potential to be used as bio-based metalworking fluids following
chemical modifications to improve their anti-wear and anti-friction capabilities |
