Abstract: A computer program includes data defining tool paths for manufacturing a component. The component geometry is estimated based on the program. Deviation of a first type is estimated as deviation between the estimated geometry and geometry of the component as defined by a 3D model. Deviation of a second type is estimated, based on machining process characteristics indicated by sensor data captured during manufacturing of the component, as deviation between a tool path a machine is instructed via the program to provide and an actual tool path provided by the machine. Deviation of a third type is computed as deviation between geometry defined by the 3D model and measured geometry of the manufactured component. An error propagation model is updated based on the estimated and computed deviations for multiple components. The error propagation model approximates relations between deviations of the first and second type and deviations of the third type.

Abstract: A sensor module for a tool holder for a cutting tool, such that when the sensor module is arranged to the tool holder having a cutting tool connected thereto, an axial portion of the cutting tool is positionable in a predefined rest position with respect to the sensor module. The sensor module includes at least one position sensor, wherein, when the sensor module is arranged to the tool holder having a cutting tool connected thereto, the position sensor is located radially spaced from the axial portion of the cutting tool for measuring deflection of the cutting tool with respect to the rest position. The disclosure further relates to a tool holder, a cutting tool, a cutting assembly, and a method for measuring deflection of a cutting tool.

Abstract: A cutting insert for cutting, milling or drilling of metal includes a sensor for detecting a predetermined wear of the cutting insert caused by operation thereof on a metal work piece, wherein the sensor includes at least two contact regions through which the sensor is connectable to external measuring circuitry. The sensor has at least two leads, which are connected to a respective of the at least two contact regions, wherein each lead presents a respective free end positioned such that, upon the predetermined wear caused by the operation of the cutting insert on a metal work piece, the free ends will be connected to each other by the metal work piece or by a chip resulting from the operation of the cutting insert on the metal work piece.
