Abstract
The invention relates to a camshaft for an internal combustion engine with a shaft and at least one cam joined therewith, which is connected via a joining surface on the cam side with a joining surface on the shaft side. The joining surface on the cam side and alternatively or additionally the joining surface on the shaft side may be constructed such that they have a predefined roughness. Hereby, the friction between the shaft and the cam can be increased. The invention further relates to a cam for such a camshaft and a method for the manufacture of such a camshaft or respectively of such a cam.
