A study on the design of CNC lathe for education and application
Abstract As the factory automation progresses, the number of specialized products increases rapidly. Furthermore, there is an increased need for engineers trained in CAD/CAM for process design and operation. This development necessitates thorough and systematic education in CAD/CAM and educational numerical control machine tools. Inexpensive educational CNC machine tools will facilitate the required education in Korea. In this study we design and manufacture a prototype of an inexpensive CNC lathe. This will facilitate the CNC education in Korea as these activities become active. The designed CNC lathe has power rating of 0.5 kW and includes a CPU board, main motor board, step motor board, and power supply board. The specification for lathe meets the KS and DIN standards.
LABORATORY CNC MACHINE FOR EDUCATION OF STUDENTS IN CONTROL SYSTEMS ENGINEERING
Modern states seek to build a society based on knowledge, and in this sense, the IPA project ADRIA HUB aims to connect students, universities and companies into a single entity in which each party realizes many benefits. Practical part of this project consists of the pilot projects related to the improvements in the woodworking industry. For the purpose of the project realization, a specific laboratory CNC machine was designed and implemented by the Laboratory for Modeling, Simulation and Control Systems at the Faculty of Electronic Engineering in Nis. CNC machine, presented in this paper, is now actively used in laboratory work. Students have the opportunity to gain practical knowledge and master the techniques of controlling this machine as part of their studies in Control Systems Engineering.
Investigations of dielectric gratings using electrodynamic models based on volume integral equations
Eigenmodes of planar and cylindrical dielectric gratings (DGs) and electromagnetic wave scattering from multiplayer DGs are investigated. The DG characteristics are calculated using numerical-analytical solution of integral equations (IEs).
