Abstract: The three rollers axial knurling process of assembled camshaft is investigated by experiment and numerical simulation, including the distributions of stress and strain and their changes on the surface of the tube, the formation process of tooth profile of the tube, the effect of parameter of knurling tools on the tools' load, the assembly interference quantity, the press-fit and torsional strength. Results show that the tooth profile formed by three point knurling technology is complete and satisfactory, and the metal can flow sufficiently, and the stress does not exceed the material failure stress. The tooth height and addendum angle are important factors in determining the tool loading, assembly interference quantity, press-fit and torsional strength. The simulation and experimental results are in good agreement, which can provide a reliable reference for the selection of axial knurling process parameters.

Key words: mechanical manufacturing process and equipment, assembled camshaft, axial knurling, numerical simulation, press-fit, static torsional strength
