The chipless form knurling is a cold forming process on the workpiece surface that requires a plasticity of the material. Depending on material and pitch of the knurl the compressed and displaced material of the surface increases and the diameter of the workpiece. The versatile applicability of form knurling allows the production of all knurls up to a shoulder and the tool can be inserted on any desired point at the workpiece. This method also enables bore-, faceand conical knurlings.
