22FTM12. Modern Green and Hard Machining of Double Helical Gears

ABSTRACT

Green machining of double helical gears can be realized by multi-axis milling, form milling, hobbing and gear shaping. The advantages and the limits of each single gear cutting method is presented in this article. Especially the multi-axis milling and the gear shaping allow the manufacturing of herringbone gears (no gap between the two helical gears), too. For the hard machining, the focus is on the multi-axis milling and generating grinding with small diameter grinding worms. The latest developments on the grinding abrasives and the machine tool enable the continuous generating grinding to become a real alternative to the established profile grinding of double helical gears.
