In this study, optimization of cutting parameters,
including the influence of the quantity and speed of cutting
fluids, were investigated in order to produce a desired surface roughness and longer tool life. A Taguchi orthogonal
array was employed to minimize the number of experiments. Yushiroken MIC 2500 cutting fluid was used as an
environmentally–friendly cutting fluid. This cutting fluid
is a boron free product and it is specially developed as a
bacteria-static type of micro-emulsion. Yushiroken MIC
2500 is suitable for grinding and cutting operations on
steel. It has a longer coolant life due to its bacteria-static
property and less foaming, and it has superior lubrication
properties in metal machining, as well as anti-rust
properties
