Reverse-handed conventional hobbing, using a multi-thread hob with a small diameter is very effective for lengthening the life of the hob and for increasing cutting efficiency. But the number of hob threads and the gear helix angle increases, the hob setting angle becomes larger, and the component of the cutting force occurs in the direction of the table rotation of the hobbing machine. While the top of the hob blade is working, the cutting force is strong eough to accelerate the table, and while it is not working, the cutting force is not strong enough. Naturally, lead error comes out at the end of hobbing. The authors are hereupon to report the cutting performance of multi-thread hobs with cutting gashes at a right angle to lead and wish straight gashes manufactured for trial when helical gears were hobbed in revrse-handed convetional.
