When the values of coordinates and gradients at some points on a work tooth profile are given, the hob tooth profile can be calculated analytically. In this report, the tooth profile of hobs with rake angle and relief angle is calculated. Transmission of rake angle error and setting error of hobs to a work is analyzed. When the allowable value of a work tooth profile error is given, the allowable value of rake angle error and setting error of hobs can be decided by this method.
