The article "The Effect of Straight-Sided Hob Teeth" appeared in the November/December 2010 issue of Gear Technology.

Summary
It is well known that hobs with straight-sided teeth do not cut true involutes. In this paper, the difference between the straight side of a hob tooth and the axial profile of an involute worm is evaluated. It is shown that the difference increases as the diametral pitch increases, to the extent that for fine-pitch gearing, the difference is insignificant.
