Aimed at a kind of rotary cutting machine, the machining process of involute gear chamfering is kinematically analyzed, and the moving locus equations of cutting edge are deduced.

The present invention relates to a stone processing machine, in particular, it relates to a multi-cutter one-step forming spherical rotary cutting machine.

The cutting element of the rotary cutting machine being a filament which is rotated at high velocity under the control of a motor, such as powered by a battery or gasoline.
