Abstract: An analytical forces model for micro-end-milling processes is developed by addressing the main factors of influence on the process in this paper. The run-out or eccentric deviation of the tool path is taken into account as well as the tool deflection. Tool deflection phenomenon affects the forces of micromilling processes significantly, smoothing tool run-out. The tool deflection phenomenon was studied by applying elasticity of materials principles to the situation of a tool under a distributed force along its edge. It was applied to two specific types of mills by designing their geometric model. Experimental results show good agreement with the model. The forces model proposed in this study can be used in process monitoring in real time as well as in adaptive control of the process.
