Simulation of toolpaths and program verification of a CNC lathe machine tool

    Machines. Technologies. Materials., Vol. 17 (2023), Issue 2, pg(s) 76-79

    This paper presents the simulation and verification of programs created for the CNC Hitachi Seiki Seicos LIII lathe machine tool. The main purpose of program simulation and verification is to ensure the quality and accuracy of the cutting process, which can significantly improve production efficiency. In addition to defining the toolpath, simulation can perform linear and circular interpolation according to specific programs based on G – codes. Therefore, all the motions of the moving parts of the real lathe machine tool can be clearly visualized. The use of simulation is a good solution not only to precise the toolpath, but also verify the program and detect any possible collision between cutting tools and mobile components, before loading the program into the lathe machine tool and starting cutting processes.


    Мathematical analysis of an electrical circuit

    Industry 4.0, Vol. 6 (2021), Issue 1, pg(s) 25-26

    There are some research about mathematical analysis of electrical circuits. In time when the scientists are in a deep search of invention new alternative ways for producing renewable energy, mathematic postulates and analysis can help optimize the const ruction of electrical circuits and prevent lost of energy. By themselves, the electrical schemas that represent Electrical circuits are a combination of interconnected electronical elements (components). According to the characteristics of the elements of Electrical schemas they are divided into the following groups: Passive and Active, Linear and Nonlinear, Bipolar and Multipolar. In our research we are going to switch from high to low power and vice versa, so we are going to us the abilities of diodes that switch from on to off state. The different values of low and high power of the electrical circuit will be represented programmatically with a cross-platform application – Arduino Integrated Development Environment and programmable language C++.

  • Massive open online course “CS50 introduction to computer science” by Harvard university implementation into Ukrainian educational process

    Industry 4.0, Vol. 4 (2019), Issue 4, pg(s) 195-197

    Nowadays online learning is among the most progressive and most popular educational practices in the world. Both European and United States universities try to implement this way of learning into the educational process. Further development and popularity, the continued blended learning implementation in Ukrainian higher education institutions, requires high-quality new online courses in various fields of knowledge, adaptations and translations of existing courses for the further leading teaching methodologies used in the educational process. Among the best courses in the world for teaching and learning computer science’s basics is “CS50 Introduction to Computer Science” by Harvard University and professor David J. Malan. This course was translated in Ukrainian and introduces in the blended format in top-rated Ukrainian higher educational facilities. The comprehensive analysis makes possible further blended learning implementation in the technical educational process in Ukraine.
