5-axis double-flank CNC machining of spiral bevel gears via custom-shaped tools—Part II: physical validations and experiments

Abstract Recently, a new methodology for 5-axis flank computer numerically controlled (CNC) machining, called double-flank has been introduced (see “5-axis CNC machining of spiral bevel gears via custom-shaped milling tools—Part I: Modeling and simulation”). Certain geometries, such as curved teeth gear, admit this approach where the tool tangential contact with material block on two sides, yielding more efficient variant machining. To achieve high accuracy, path-planning algorithm, however, does not look only path tool, but also shape itself. The proposed is validated by series physical experiments using an abrasive specifically designed particular type gear. potential shown in semifinishing stage gear manufacturing, it outperforms traditional ball end order magnitude terms time, while keeping, or even improving, error.
