For the process of forming member gear, the machine setting parameters for Free-form generators can be determined by either direct or equivalent transformation, both methods coincide with each other. For generated pinion, the author utilizes a imaginary modified member gear to get original machine setting parameters for traditional cradle-type generator, and then establishes a mathematical model including the second and third order contact parameters of the gear pair for optimal synthesis to optimize the quality of contact transmission of the gearing.
