S111042 Fundamental Discussions on Internal-Gear Skiving

Abstract

Gear skiving is not a new method. It is a gear cutting method with a gear-type tool in which work- and tool-gears mesh with each other with a shaft angle between their axes, and the tool-gear is fed along the work-gear axis. The shaft angle yields flank sliding along a gear axis which can play a cutting action. Therefore, skiving can be expected to realize a high productive gear cutting method especially for internal gears. The present paper describes an example of tool edge shapes which are calculated on the basis of the gearing theory.
