KT and KR specific shear force coefficients were used to predict the shear forces. In fact, several models of prediction of shear forces were proposed in previous investigations for conventional size machining processes. However, the final micro milling processes were known as different phenomena with respect to the final macro milling. Many of the previous investigations tried to complicate the different models of final micro-milling since macro milling. However, the shear force models for macro and micro milling were based primarily on shear forces measured for a number of experimental machining processes. Next, the shear force model proposed by Tlusty, which was developed for macro final milling, was applied for micro-end milling because this model is relatively simple. The finite element method was used to predict the deflection of the tool according to the predicted shear forces. The planned tool deflection amounts and the actual machined profiles were compared to each other to check the differences between them.
