主 题：face gears worm grinding worm dressing geometrical analysis closed-loop manufacturing
摘 要：Worm grinding has been applied to manufacture gears to pursue high accuracy and fine surface *** the worm used to grind face gears is manufactured with multi-axis computer numerical control(CNC)machining,the machining accuracy is usually improved by increasing the number of tool paths with more time ***,this work proposes a generated method to improve the efficiency by dressing the worm surface with only one path,and a closed-loop manufacturing process is applied to ensure the machining *** to an advanced geometric analysis,the worm surface is practically approximated as a swept surface generated by a planar ***,this curve is applied as the profile of a dressing wheel,which is used to dress the worm *** practical machining is carried out in a CNC machine tool,which was originally used to grind helical ***,a closed-loop manufacturing process including machining,measurement,and modification is proposed to compensate the machining *** proposed method is validated with simulations and practical experiments.
