It has been concluded in previous studies that Cubic Boron Nitride (CBN) tools have greater wear resistance and superior
tool life than other tool materials used in conventional milling, due to chemically stability at high temperatures, high
abrasive wear resistance and high degree of hardness; however no research has been conducted about its performance on
micro milling. Burr formation has a direct negative effect on product quality and assembly automation in micro milling,
therefore adoption of machining strategies and influencing factors were investigated intending to reduce burr formation.
This paper also aims at analyzing the interference of cutting parameters on micro milling with CBN tools, such as the
influence of cutting speed and feed per tooth on the surface quality and tool life. These outcomes enable us to know
which parameters and strategies must be used to achieve better results when micro milling steel with CBN tools.
