Micro-milling seems to be a scale down machining operation of macro-milling but there are differences between these processes. In micro-milling, diameter of cutting tool (D) used is less than 1 mm while in macro-milling it is greater than 1 mm (Ali et al., 2012; Ducobu et al., 2009; Jaffery et al., 2016; Mian et al., 2010; zel et al., 2011
