Micro end milling is one of the manufacturing processes that produces micro topography using mechanical removal of chips. Its modeling presents some peculiarities compared to meso scale process. This article presents a mechanistic model for micromilling process considering homogeneous grain properties. It is not taken into account dynamic behavior of tool and interaction between tool-workpiece due to stiffness or grain variation. The model uses calibration method based on experimental data used to calculate specific pressure. The design of experiments considers feed rate and cutting velocity as factors and resultant force as the output. The model is validated using experiments inside the DOE factors range. The result presents the comparison between calculated and experimental values for the cutting force and the maximum error presented 8% of difference.
