Abstract:

Only such tools could be used for high precision machining of shaping surfaces, the profiles of which do not change at resharpening. The backward turned hobs are appropriate for this purpose. In case of logarithm spiral backward turned curve the profile constancy can be provided in case of the repeated resharpening of hob.
