“…The uncut material is pushed out of the top of the slot, which is in the direction with the lowest resistance, thereby generating a large irregular tearing burr on the down milling side. Therefore, for ductile material micro milling, the surface quality on the up milling side is better than that of the down milling side as reported in [6,7] and confirmed in this research. Based on the top burr formation mechanism, a burr control strategy with the aid of vibration is proposed.…”

“…The Johnson-Cook (JC) material constitutive and damage models are used to model material plasticity and damage respectively. Details of the JC model parameters of the material can be found in [11]. The coefficient of friction between tool and workpiece is set at 0.6.…”

“…Instead of measuring techniques, research has been focused on burr reduction for micro-milling, through experimentation [9,12,32,35] or simulation [36][37][38] by varying the process parameters or deburring after machining. The formation of burrs in the macro-milling process has been studied extensively through experimental and predictive analytical modeling, but in the micro-scale, very little work has been reported in the literature.…”
