A method for controlling a production process for components, wherein the components or a production device used for producing the components have or has features which are metrologically detectable. The method comprising specifying a test plan for detecting primary feature(s) and secondary feature(s) by tests, wherein the primary feature(s) is/are measured at a first test frequency and the secondary feature(s) is/are measured at a second test frequency, wherein at least one stability criterion is defined for the primary feature(s); producing the components and carrying out the test plan for producing test results in parallel, wherein solely the primary feature(s) is/are tested at the first test frequency; evaluating the determined test results; and, if at least one test result for the primary feature(s) violates the stability criterion, continuing the carrying out of the test plan, wherein at least a secondary feature is tested.

Method for controlling a production process for producing components

At least one parameter of a material is determined with a pressing tool usable for producing a green compact and a pressing tool for producing at least one green compact. The pressing tool has at least one planar surface which is formed at least in part by a die which, starting from the surface, extends along an axial direction and, on the surface, has a cavity which extends from the surface along the axial direction and has an inner circumferential surface; wherein the cavity forms a receptacle for a powdery material which can be pressed in the cavity by at least one punch plunging into the cavity along the axial direction to form the green compact.
