Tooth surface configurations caused by the errors in hobs and hobbing machines.
Estimation of the errors of a hob and a hobbing machine is necessary in order to improve the hobbing accuracy. This paper focuses on the configurations remaining on the tooth surfaces of hobbed gears, and illustrates analytically the tooth surface configurations caused by the errors of the hob and the hobbing machine.
