This article is a continuation of previously published articles. This paper briefly describes the positive and negative qualities of asymmetric gearing from the point of view of loading conditions applied at the gearset, and the development and latest update of the software for designing this special involute gearing. The precise profile of the manufacturing tool is also described. All display options, and the option of gear mesh animation using this program, is shown. All equations necessary for the gearing geometry description, and a special approach with respect to x-shift coefficients distribution, are also mentioned in this paper.
