METHOD AND DEVICE FOR PRODUCING A PRODUCT AND COMPUTER PROGRAM PRODUCT
The disclosure relates to a method and a device for producing a product and to a computer program product. The product is produced in at least one production step. A quality control check is optionally carried out after at least one of the production steps to determine a quality index of the product in question. To save on the quality control check, a quality indicator of the product in question is determined using production data. The production data are advantageously provided by sensors. The quality indicator of the product in question may be calculated using an adaptive algorithm. The adaptive algorithm may be taught and/or improved using quality indices of a quality control unit and the corresponding production data. The adaptive algorithm may be taught with the aid of a further computing unit, in particular in a cloud.
ONLINE MONITORING OF ADDITIVE MANUFACTURING USING ACOUSTIC EMISSION METHODS
Embodiments provide systems and methods for utilizing acoustic sensors to detect defects via online or in situ monitoring of additive manufacturing (AM) processes. Sensors may capture acoustic waves associated with AM manufacturing operations. The acoustic emissions in combination with other sensing data, such as cameras or thermometers, may be used to characterize the state of the AM process, such as to detect a defect has occurred or confirm a defect has not occurred. When defects are detected, the AM process may be stopped to prevent further processing of a defective part. When defects are predicted as likely to occur, operational parameters of the AM device or process may be adjusted to mitigate the occurrence of a defect. The techniques disclosed herein enable detection of defects that occur underneath the surface of the part being manufactured, as well as correct issues with the AM device or process before a defect occurs.
EVENT MONITORING AND CHARACTERIZATION
A system, method and software for generating and receiving information about the AC, DC, RF, voltage, and other characteristics and information provided by components in a system. The information can provide insight into the operational characteristics and functionality of the components, as well as the process and system the components are being used within. This information may be used for preventative maintenance of the components, and to detect changes, issues, failures, events, problems, etc. in the process and system.
Metal Additive Manufacturing Qualification Test Artifact
A test artifact for additive manufacturing is provided. The artifact comprises an additively manufactured singular continuous body between 100 cc and 6 cc in bounding box volume and between 50 cc and 3 cc in solid body. The body comprises at least three fiducials positioned for identification of locations in cross-section after sectioning of the artifact and at least three geometries that are unique from each other when exposed in cross section.
Substrate processing apparatus, method of monitoring abnormality of substrate processing apparatus, and recording medium

The message and feedback subsystem generates an alert signal and a feedback signal according to the output signal, and the alert signal is transmitted to a user of the semiconductor manufacturing equipment.
PRODUCTION AND MEASUREMENT OF WORKPIECES
In a workpiece production method a plurality of nominally similar workpieces are produced in a production process on one production machine. The order or time of production of some of the workpieces on the production machine is recorded. Some of the workpieces recorded are measured at two or more inspection stations. Dimensions or points of one workpiece are measured at one of the inspection stations, and corresponding dimensions or points of another of the workpieces are measured at another of the inspection stations. The results of the measurements of corresponding dimensions or points made at the two or more inspection stations are analysed together, taking account of the order or time of production of the workpieces. An output signal is produced based on the analysing of the results together. The output signal indicates performance of the production machine or of one or more of the inspection stations.
