A method forms a crowning on a sintered component made from a sintering powder, in particular on the teeth of a sintered component including a toothing. The sintered component is calibrated in that the sintered component is introduced into a calibration tool. The sintered component includes a forming chamber with at least one forming wall. In the forming wall a crowning is formed which is inverse to the crowning of the sintered component to be formed. After calibration the sintered component is removed again from the calibration tool. The size of the forming chamber of the calibration tool remains unchanged at least for the time period beginning with the insertion of the sintered component into the calibration tool and ending after the removal of the sintered molding from the calibration tool.
