Method for manufacturing three-dimensional monolithic component e.g. cam shaft, involves transforming component by cooling at different cooling speeds such that component hardness is set in specific range

The method involves heating a material deforming tool (10) with monolithic component (14) in receiving area (13) to an initial temperature, where the range of initial temperature is set according to the strength of component. The component is transformed by cooling at different cooling speeds such that the component hardness is set in the range of 45 HRC or more. Independent claims are included for the following: (1) three-dimensional monolithic component; and (2) tool for manufacturing three-dimensional monolithic component.
