Research on formation principle of cutting-edge geometries of carbide turning tools

Cutting-edge geometries directly influence tool life and performance. Appropriate cutting-edge geometries can enhance wear resistance, ensure process reliability, and maintain workpiece integrity. In this work, the single-factor and multi-factor abrasive water jet machining experiments were conducted to explore the factors influencing the formation of the cutting-edge, including jet pressure, angle, and number of strokes. It was found that different jetting parameters have varying effects on different cutting-edge parameters. Jetting pressure most impacted the radius of the cutting-edge formation, while angle significantly affected shape factor K. Multi-factor experiments demonstrated that both pressure and tool orientation significantly affect process stability.
