Effect of Tool Rotation Erroron the Topography of Flank Machined Surface

In the flank milling process, processed metal surface is formed by the edge of the cutting tool and affected by errors of it in the manufacturing process. Among those errors, the error of tool rotation movement has the most significant effect on machined surface. This article focuses on the machining process influenced by cutting tool rotation errors in the NC machining process. In this paper, a mathematical model of machining process is built. The effect of tool offset error and tool tilt error on tool deflection error is studied. A method of detecting tool rotation errors through machined surface topography is presented in the paper.
