As a finishing of the gear, the gear honing is often used recently. Processing cost is sharply reducible if honing processing for work gear with different number of teeth can be carried out using one dressing gear. Moreover, when the work-gear's number of teeth and module is small, the grinding wheel generated by the dressing gear with different work-gear's number of teeth processes the work gear. The geometric relation of three tooth surfaces (dressing gear, grinding gear, and work gear) has already been clarified. And, the tooth profile and lead error produced on the work gear tooth surface has been calculated by numerical calculation. In this paper, the lead and profile error produced on the work gear was investigated, when a dressing was repeated. Consequently, it turned out that a lead error becomes large as the dressing goes on, and, adopting the variable shaft angle system is effective in order to lessen the error.
