Its integrated sizing function makes KISSsoft software a powerful tool, giving engineers an easy way of finding better solutions. In addition to specific sizing calculations for individual parameters (profile offset, tolerances, wheelbase, etc.), design calculations for cylindrical gears also involve two program modules that together perform calculations for complete gearing solutions. Conceptual design is the very first step in the design process, which, besides resulting in a first draft, most importantly provides information about fuzzy design parameters (meaningful wheelbase and module ranges). Precision design serves as a means of optimizing a specific gearing definition and provides an efficient tool for finding solutions that, for instance, run especially quietly or that have a high load-bearing capacity.
