“…Dexel-based simulation methods, as shown in Figure 1, consist of a grid of line segments which can be regarded as parallel nails or rods, whereby length can be varied to change the overall shape. Dexels are commonly used for the simulation of subtractive processes, for instance, turning, milling and grinding [11]. In contrast to CSG, the Dexel model is also suitable for objects with interior regions as lattices or pores [12].…”

Additive manufacturing is typically a flexible alternative to conventional manufacturing processes. However, manufacturing costs increase due to the effort required to experimentally determine optimum process parameters for customized products or small batches. Therefore, simulation models are needed in order to reduce the amount of effort necessary for experimental testing. For this purpose, a novel technological simulation method for directed energy deposition additive manufacturing is presented here. The Dexel-based simulation allows modeling of additive manufacturing of varying geometric shapes by considering multi-axis machine tool kinematics and local process conditions. The simulation approach can be combined with the simulation of subtractive processes, which enables integrated digital process chains.

“…A separate embodiment of such environments can be considered commercial complexes of numerical analysis and implementation of engineering calculations, simulation of production processes and design work [1,5] with built-in means of visualization of intermediate and final results of learning experiment in widespread forms. However, considering the profile requirements for the qualified professionals training and the degree of prior background of the target audience, as well as given the existing specialties and educational trajectories at implementation presence of such computerized laboratory workshops and to prevent the accumulation of large number various software, it is necessary to focus on formalizing industry-oriented structures components [6,7] and deployment of unified client-server cross-academic virtual learning experiment platform.…”

The methodology of a virtual laboratory workshop organizing on the example of research of technological stages lamination of a printing order in the production process of post-press processing of printed products in the training of qualified specialists in engineering specialties is presented. Despite the extensive coverage in open sources a features application of commercial complexes of simulation modeling in the educational process, the performed analysis showed the need to design an original client-server virtual platform for learning experiment and further development of industry-oriented structural components as pedagogical toolkit for it. Therefore, a software engine is proposed with the support of relevant program libraries and up-to-date information from the corporate database of the enterprise for operational computation and dynamic management of the active education environment based on requests and subsequent decision-making, when the student independently builds a strategy to achieve the goal by means of the most adequate simulation models. The applied architecture of the software engine presupposes the presence of interdisciplinary skills allows the academic media platform of the learning experiment to work in three educationally oriented modes and provides work experience close to the production one.
