We present a portfolio of natural legal language processing and document curation services currently under development in a collaborative European project. First, we give an overview of the project and the different use cases, while, in the main part of the article, we focus upon the 13 different processing services that are being deployed in different prototype applications using a flexible and scalable microservices architecture. Their orchestration is operationalised using a content and document curation workflow manager.
This article focused on comparing of the properties of the two most used materials, Acrylonitrile-Butadiene-Styrene (ABS) and Polylactic Acid (PLA), in the Rapid Prototyping (RP) process using the Fused Deposition Modeling (FDM) method. The thin-walled components were manufactured by Zortrax M200 and DeeGreen 3D printer. Print settings and printer parameters are also mentioned in the article. The printed models were 3D digitized using the GOM ATOS Triple Scan II optical 3D scanner. Main section is focused on the analysis of individual components in the GOM Inspect software. Authors used this software to measure the individual distances. The last section of the paper focuses especially on the evaluation of obtained results in the form of tables and a chart.
Abstract. The article is focused on research of the influence of the layer thickness in the Fused Deposition Modeling (FDM) additive manufacturing method on shape geometrical and dimensional accuracy of parts. The digital model of the object (upper teeths) was obtained by intraoral 3D scanner 3Shape TRIOS used in dentistry. Based on the 3D (Three Dimensional) scanned digital model, the manufacturing of the upper teeths was realized on the FDM 3D printer Zortrax M200. The parts were manufactured in three different layer thicknesses. The manufactured parts was digitized by optical 3D scanner GOM ATOS Triple Scan. The dimensional and shape accuracy of the parts was evaluated in the software GOM Inspect.
This paper is focused on the issue of preparing the cutting edge microgeometry of cutting inserts made of cubic boron nitride (CBN). The aim of this research was to investigate the possibilities of rotary ultrasonic machining (RUM) for preparing asymmetric cutting edge microgeometries of various shapes (chamfers, circular, and elliptical rounding and their combinations) on a CBN cutting tool. In this article, a new type of advanced cutting edge preparation method is presented. CBN is relatively resistant to the most often used (abrasive) methods of cutting-edge preparation, due to its very high hardness (which is a prerequisite property for machining difficult-to-cut materials). Such hard materials could be processed using advanced manufacturing methods, and rotary ultrasonic machining (RUM) is one such method. Experiments have shown that RUM can be used for machining CBN. However, high hardness is not the only challenge here. For cutting edge preparation, it is necessary to achieve an adequate accuracy of size and dimensions. The presented paper analyzes the suitability of the RUM process for processing CBN inserts. The results of the experiment showed that this method can be used for preparing asymmetric cutting edge microgeometries with various shapes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
