A computer program product for numerically correcting an endpoint position of a Coordinate Measuring Machine (CMM) implemented on a computing unit, receiving as input temporally resolved information from a set of sensors attached to or integrated into the CMM, and to a method for numerically correcting an endpoint position of a CMM, wherein errors between a targeted endpoint position and an actual endpoint position reached during a measurement process are numerically compensated through the use of the computer program product.

Dynamical modeling of CMMs for numerically correcting measurement results

Object analysis comprising measuring a frequency-dependent natural oscillation behavior of the object by dynamically-mechanically exciting the object in a defined frequency range (f) by means of generating a body oscillation by applying a test signal, and detecting a body oscillation generated in the object on account of the exciting. Moreover, the method involves simulating a frequency-dependent natural oscillation behavior for the object by generating a virtual digital representation of the object, and carrying out a finite element analysis on the basis of the virtual representation comprising dynamically exciting, in a simulated manner, the virtual representation into a virtual frequency range for generating a virtual body oscillation, calculating the virtual body oscillation generated in the object on account of the exciting in a simulated manner, and deriving an object state on the basis of a comparison of the measured natural oscillation behavior and the simulated frequency-dependent natural oscillation behavior.

Oscillation analysis on an object produced by means of additive manufacturing

An additive manufacturing apparatus for manufacture of aluminum parts layer-by-layer, the apparatus comprising an eddy current sensor for in-process measuring of contour and defects of manufactured layers with a defect resolution of at least 0.25 mm. Preferably, the eddy current sensor is embodied as a differential mode line sensor with dual use of sensor coils. Preferably, the array of the line sensor comprises a zig-zag-arrangement of sensor coils with a cross section of 0.15 mmmaximal and with a core with an initial magnetic permeability of at least 5000, preferably a permalloy or metal glass coil core.

Eddy current sensor array and eddy current sensor system for additive manufacturing

A system comprising at least one mobile vehicle configured to move autonomously. The mobile vehicle comprises a spatial localization system, an autonomous navigation and propulsion unit, a local edge computation unit for a local data analysis at the mobile vehicle by intelligent, dynamically deployable edge analytics software agents, and a communication interface providing a data link to other devices. The system utilizes an automatic deployment of a workflow comprising at least one current task. A mobile measurement vehicle with a spatial measurement sensor unit is configured to establish a temporary instance of a local spatial reference cell for a subset of multiple mobile vehicles and a work piece. The temporary instance of the spatial reference cell is established temporally and is established with an individual level of spatial accuracy and individual limited local range, which individual level is dynamically defined by an accuracy requirement of the current task.

Mobile vehicles in manufacturing

A system for providing state information for at least a part of a tool positioning machine embodied as manipulating machine or as coordinate measuring machine is provided. The system comprises the tool positioning machine defining a machine coordinate system and having a base and a machine structure. The structure comprises a tool head and structural components for linking the tool head to the base, at least one drive mechanism for providing movability of the machine structure relative to the base, a position determining system for deriving at least one coordinate of the machine structure in the machine coordinate system and a controlling unit adapted for controlling movement of the machine structure. The system comprises a calibration setup. A calibration component is mounted on the machine structure and defines a moveable reference point, another calibration component is arranged with defined spatial relation to the base and provides a nominal calibration position.
