For state variables transformation between the old meshes and new meshes, a directinterpolation transformation method is introduced which deduce the transformation errors.
A directinterpolation algorithm of spiral bevel gear NC machining is proposed, thus establishing the relationship between the motion of the cutter-head center and the rotation of the work gear.
