Error compensation for helical gear hobbing

High-speed dry hobbing is a new technology for gear machining,It is an efficient manufacturing process for machining spur and helical gears.However,High-speed (spindle speed 1200r/min) cutting speed fluctuation is large, especially for helical gear machining, which requires two sets of electronic gearboxes for multi-axis synchronous control.Therefore, the machining error compensation...
