Research on Machining Archimedes Worm by Internal Whirlwind Milling

Aiming at the problem of over cutting in the process of worm internal whirlwind milling, the Archimedes worm was selected as the research object, the forming mechanism was studied by using the method of coordinate transformation, and the mathematical model of internal whirlwind milling was established based on the characteristics of intermittent cutting. By setting different control groups, the influence of tip circle diameter and cutter head inclination angle on overcutting degree was analyzed. The machining simulation analysis in VERICUT was carried out to verify the correctness of the mathematical model of internal cyclone milling.
