Abstract

As a prospective machining method for cylindrical gear, gear skiving has been promoted by many commercial companies, such as Gleason, Mitsubishi and Prawema recently. Although the principle and mathematical model for gear skiving has been discussed by many works, the tooth modification has left behind in literature. In fact, machine kinematics correction and tooth contact analysis (TCA) are widely used for tooth modification in gear processing, such as hobbing, grinding and milling. Focusing on this, the paper generalizes machine kinematics correction and tooth contact analysis to gear skiving. The influence of the modification parameters on tooth deviation, contact path and transmission error are all investigated, showing that localized contact pattern and polynomial transmission error can be realized through cutter offset correction for one gear and cutter tilted (or crossed angle) correction for the other gear.
