The identification of tool eccentricity parameters in micro-milling

Milling tool eccentricity has great influence in micro-milling. It could cause single edge cutting phenomenon, and effect machining quality and tool life. To recognize tool eccentricity parameters, on the basis of the tool eccentricity model, cutting edge trajectories are analyzed, and then a tool eccentricity identification method is proposed. The parameters of identification model are obtained by experiments and tool eccentricity parameters are calculated by iterative method. Finally, the accuracy of the proposed method is verified by measuring the diameter of a milled hole, and the verified result shows the proposed identification model is effective. © 2016 SERSC.
