A method for monitoring a production process with regard to quality is disclosed. The method includes: a) breaking down the production process into a sequence of individual steps, defined by a sequence of control commands for a production program for carrying out the production process on a machine tool; b) generating at least one signal template per individual step of the production process from the control commands for the individual steps, each signal template corresponding to a theoretical signal curve for a parameter which may be measured upon executing the production process; c) measurement of a signal curve for at least one parameter per individual step during the execution; and d) comparison of the or each measured signal curve with the respective arithmetically generated signal template, wherein a qualitatively poor production process is determined if the measured signal curve deviates from the signal template by more than a given tolerance.

Method for monitoring a production process

The present invention relates to a method for determining a selected machining quality of components in a manufacturing process, particularly during metal cutting, having at least the following method steps of determining process-relevant variables by sensors and/or from the data stream in the machine controller, extracting variable curves characteristic for the respective machining process, selecting a number of different characteristics of the extracted variable curves, the linking of which enables a clear assignment to the selected machining quality, and multivariate linking of the selected characteristics to a characteristic pattern correlating with the selected machining quality.

Method for determining the machining quality of components, particularly for metal cutting by NC machines

A chuck-integrated force-measuring system for determining cutting forces at the cutting tool tip of a rotating tool, for example a drill or milling cutter having at least one measuring sensor, as well as a measured-value processing station. The at least one measuring sensor is designed as a strain sensor which is placeable on a tool holder of a machine tool. A measuring hub assembly is also provided which is insertable as an adapter piece into the chuck of the machine tool and is designed with its own chuck for receiving the tool, the at least one measuring sensor being integrated in the adapter piece.
