The modern stage of development of CAD-systems is characterized by a significant expansion of the scope of their use. An interesting direction for improving CAD systems is their integration with CAM systems. One of the main tasks solved by CAM systems is the development of control programs for CNC machines. Many software developers for automation of design and technological preparation of production have already equipped their systems with appropriate modules. These circumstances pose an urgent task for higher educational institutions to introduce the study of integrated CAD/CAM systems into the educational process of training design engineers. In this case, the emphasis should be placed on the practical mastery of the skills of developing control programs using a 3D-model of the manufactured part. The stages of preparation for the implementation of the system are described, starting with the analysis of the market of necessary software products and ending with the adaptation of the licensed system to the conditions of use in the educational process of the university. A link is given to the description of the methodology used in the assessment of automated systems at the stage preceding the tender for their purchase. It is emphasized that the study of the possibility of using a CAD/CAM system in the preparation of design engineers was carried out by students during the course and diploma projects in the discipline “Automated systems for technological preparation of production”. The methodology for designing control programs used by students is given, and the results obtained are assessed.

Abstract Expert systems can be integrated with databases and CAD/CAM systems using group technology (GT). By using information in a database, geometric features of parts can be specified by GT codes, and CAD models can be generated automatically using parameterized generic templates. This paper describes a microcomputer-based prototype implementation that merges database, expert, and CAD systems in order to perform GT classification and create CAD models with minimal manual intervention.

Research Analysis

The information support of the product life’s cycle requires to produce and to design this product with the help of the modern graphic CAD packages by creating an information model. In this regard, the question of the introduction of information technology in the educational process of the graphic training becomes relevant, as the basic graphic training forms the skills of graphic presentation of information. The purpose of the article is to substantiate the content of graphic training in institutions of higher technical education in conjunction with special software CAD-systems, including SolidWorks. The purpose of the study is to substantiate the content of graphic training in institutions of higher technical education in conjunction with the special software CAD-systems, including the SolidWorks. The methods of the research: analysis of the problems of future bachelors-mechanics’ graphic training, analysis of modern software for the graphic documentation, the generalization to obtain the conclusions and recommendations. The research results demonstrate that the development of modern software to solve problems of automation of three-dimensional design, the design and technological preparation of production of any complexity in various industries allows graduates to be competitive professionally in the labor market. We considered the graphic training in the environment of CAD-systems, also we highlighted the features of a special software SolidWorks-CAD. In the course of research of the content of basic graphic training that includes the descriptive geometry, the engineering and computer graphics in CAD-systems they revealed the most important factors in the formation of methods of mental activity of students. We consider that the most progressive method of the graphic training of engineers is to teach two courses instead of the three classic parts of basic graphic training. The effected research of engineering graphics and the peculiarities of the construction of working drawings in SolidWorks allowed to reconcile their relationship. The mastering of the modern software for solving of the problems of automation of three-dimensional design, the design and technological preparation of production of any complexity in various industries allows for graduates to be competitive professionally in the labor market.

Abstract Due to the incomplete representation schemes and the lack of high-level reasoning capability of current CAD/CAM systems, manufacturability assessment is performed by experienced designers and manufacturing engineers. The problems associated with automating manufacturing assessment include (1) the integration of a knowledge based environment within a design environment to provide reasoning capability, and (2) the development of flexible, modularized and responsive part models with levels of abstraction to support high-level reasoning which is required. Since modification of part geometries are frequently made during manufacturability assessment, the capability for part geometry modification is required at the level of interacting procedures. Consistency problems therefore occur between the geometric database in design environment and the part model in knowledge based environment. This paper presents a framework for an integrated design and manufacturability assessment environment which address these concerns.

The article studies the necessity and features of transformation of the educational system under conditions of accelerated development in the digital economy. Particular attention in the context of this transformation is given to significance and possibilities of digital literacy, which forms the whole complex of fundamentally new requirements for all participants in the education system. The authors argue that the current stage of development of the digital economy requires the education system not only to digitalize its individual elements and links, but to apply a fundamentally new integrated approach that would transform the education system while taking into account new goals, structure and content of the educational process. The authors define digital literacy as the ability to form and apply educational content through digital technologies. The article gives particular emphasis on the significance and potential of individualizing the educational trajectory and the concept of continuing education. The authors consider the main factors in the development and achievement of the level of digital literacy, considering the requirements that the digital economy is currently imposing on the educational system.

The purpose of this in vitro study was to evaluate marginal and internal fits of ceramic crowns fabricated with chairside computer-aided design and manufacturing (CAD/CAM) systems. An experimental model based on ISO 12836:2015 was digitally scanned with different intraoral scanners (Omnicam (CEREC), EZIS PO (DDS), and CS3500 (Carestream)). Ceramic crowns were fabricated using the CAD/CAM process recommended by each system (CEREC, EZIS, and Carestream systems; N = 15). The 3-dimensional (3D) marginal and internal fit of each ceramic crown was measured using a 3D inspection software (Geomagic control X). Differences among the systems and various measurements were evaluated using the Kruskal–Wallis test. Statistically significant differences were validated using pairwise comparisons (α = 0.05). Occlusal gaps in the CEREC, EZIS, and Carestream groups were 113.0, 161.3, and 438.2 µm, respectively (p < 0.001). The axial gaps were 83.4, 78.0, and 107.9 µm, respectively. The marginal gaps were 77.8, 99.3, and 60.6 µm, respectively, and the whole gaps were 85.9, 107.3, and 214.0 µm, respectively. Significant differences were observed with the EZIS system compared with the other two systems in terms of the marginal gap sizes. The CEREC system showed no significant differences among the four measured regions. However, the EZIS and Carestream systems did show a statistically significant difference (p < 0.05). All three systems were judged to be capable of fabricating clinically acceptable prostheses, because the marginal gap, which is the most important factor in the marginal fit of prostheses, was recorded to be below 100 µm in all three systems.
