摘要：
In micro-milling, tool runout caused by manufacturing and clamping errors has a great influence on milling force, surface topography, tool life, etc. In this paper, the influence of tool runout parameters on actual cutting radius in mesoscopic scale is analyzed. A new method for in-position identification of tool runout parameters is then proposed. First, the formula for the actual cutting radius of the cutting edge of the considered tool runout is deduced and then used to analyze the influence of tool runout on the actual cutting radius. On this basis, an analytical model for tool runout parameters is established, and the model parameters are obtained by displacement measurement. Finally, tool runout parameters are identified and analyzed by an iterative algorithm, and the obtained result is verified by the milling experiment. The results show that the proposed method of the tool runout length based on displacement measurement is simple and easy to operate and has high resolution and efficiency. It can also be applied to the identification of tool runout parameters in conventional milling. Copyright ©2021 Journal of Harbin Engineering University.
