Abstract:
The article deals with an innovative method of dynamic magnetic strengthening, which allows performing surface plastic deformation by balls through the use of magnetic field energy of a tool. The article describes the design of a tool for expanding holes of machine component billets, which differs from the known ones by presence of a magnetic system with cylindrical permanent magnets. The paper gives recommendations on the choice of rational modes of the strengthening process, which minimize surface roughness of machine component billet.
