Abstract
A method for operating a press, wherein a relationship between a detected component property (current value) of the final product (e.g. surface quality), the provided material property of the semi-finished product (e.g. sheet thickness), and the detected production parameter (e.g. pressing pressure) is determined, for example, by a self-learning algorithm, on the basis of precedingly determined differential values between target and current values of the component property. The algorithm is subsequently used for targeted selection of samples for quality monitoring.

A method for operating a press, in which semifinished products are shaped into components, the method comprising:
- providing at least one material property of at least one semifinished product;
- detecting at least one production parameter that characterizes a status of the press during shaping of the at least one semifinished product to form at least one respective shaped component;
- selecting the at least one shaped component from a set of shaped components on a basis of the at least one material property of the at least one semifinished product underlying the at least one selected shaped component and/or on a basis of the at least one production parameter detected during the shaping of the at least one selected shaped component by way of an electronic computing device;
- detecting at least one component property of the at least one selected shaped component by way of a measuring device;
- determining at least one difference value describing a deviation of the detected component property of the at least one selected shaped component from a target value predetermined for a component type of the at least one selected shaped component;
- and
- providing the at least one difference value.
A non-transitory electronically readable storage medium having items of electronically readable control information stored thereon that, when executed by an electronic computing device, cause the electronic computing device to perform a method comprising:
- providing at least one material property of at least one semifinished product;
- detecting at least one production parameter that characterizes a status of the press during shaping of the at least one semifinished product to form at least one respective shaped component;
- selecting the at least one shaped component from a set of shaped components on a basis of the at least one material property of the at least one semifinished product underlying the at least one selected shaped component and/or on a basis of the at least one production parameter detected during the shaping of the at least one selected shaped component by way of an electronic computing device;
- detecting at least one component property of the at least one selected shaped component by way of a measuring device;
- determining at least one difference value describing a deviation of the detected component property of the at least one selected shaped component from a target value predetermined for a component type of the at least one selected shaped component;
- and
- providing the at least one difference value.
