Abstract
Tool edge preparation can eliminate defects and realize hone cutting edge, which can improve the quality of the workpiece surface, elevate the stability of cutting process and the tool life. In order to better investigate the edge preparation mechanism, the influence law of the edge preparation process parameters on the cutting edge is analyzed. The paper presents the single factor experiments and orthogonal experiments with the cemented carbide milling tool spindle rotation rate, edge preparation time, abrasive size and abrasive ratio in drag finishing. The edge preparation mechanism is revealed in the paper, which provides basis for the structure optimization of cutting edge contour.
