The Identification of Tool Eccentricity Parameters in Micro-Milling
International Journal of Smart Home
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
... d. 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. 26 Copyright ⓒ 2016 SERSC model, which takes into account the impact of tool eccentricity and the scale effects in micro-milling. Then iterative algorithm is used to calculate the minimum standard deviation square sums of cutting force coefficients, which tool eccentricity parameters could be considered as the actual parameters. Therefore, this paper analyzed the tool path, which in view of tool eccentricity, and then proposed a tool eccentricity identification method which based on analytic geometry. effect of tool eccentricity is analyzed, and a criterion of single edge cutting phenomenon is proposed. Finally, a tool eccentricity parameters identification method is proposed which is based on analytic geometry. In this method, tool eccentricity parameters are calculated by iterative algorithm. The measurement of milled hole diameter which is observed by confocal microscopy confirmed the validity and the applicability of the identification method.
