It concr etely analyze two kinds of machining way of double envelope method and also gives the correspondenr algorithm about its puts forward the theorythat the instant aneous contact line making way of the rolling tool is more reasonable.

Research on machining tool location controlling method of cylindrical cam based on double envelope principle

For the cylindrical groove-cam with translating roller follower, the cutter location control methods of cylindrical cam based on double envelope principle were studied with the theory of conjugating surfaces.
