Edge Treatment by Tip-Burnishing Process with an Active Rotary Tool

Abstract:

A novel edge treatment method that utilizes a tip-burnishing process with an active rotary tool developed by the authors was proposed. Two types of burnishing process experiments were conducted using the tip-burnishing process to deburr the workpiece edge and create a sharp cutting edge. Furthermore, an evaluation test for the cutting performance of the sharp edge, which was treated using the developed burnishing process, was conducted. In the deburring experiment, superior deburring was achieved by generating a sliding effect orthogonal to the burr generation direction. An experiment was conducted for evaluating the sharpening of the cutting edge; it was observed that the cutting-edge angle decreased due to the burnishing process. A cutting performance test was conducted using a wedge-shaped workpiece before and after burnishing. The cutting performance of the workpiece was quantitatively evaluated based on the load and stroke required for the cutting of the sheet material.
