    摘要: A method for manufacturing pressed parts from hard metal, ceramic, sintered metal or likewise, in which a part of a charge of a powder-like or granular original material is filled into a pressing mould and is pressed with at least one pressing stamp against a counter surface, wherein the force and the distance of the pressing stamp are measured, and wherein there are the following method steps:depending on the geometry of the pressed part and on the original material during the compression for a pressing stamp a desired force-distance diagram (nominal curve) is determined and stored;in a computer during the compression the measured values for the distance and the force of the pressing stamp are compared to the nominal curve;by way of at least one separately actuated section of the pressing stamp or of a separate stamp the pressure on the pressing material during the compression phase is increased or reduced as soon as a deviation from the nominal curve is determined, in order at the end of the compression phase to obtain an equal density of each pressed part.
