Item Розмірна обробка електричною дугою складних за зовнішнім контуром деталей(КНТУ, 2015) Носуленко, В. І.; Юр’єв, В. В.; Nosulenko, Viktor; Yuriev, VitalyОписано технологічну схему формоутворення розмірної обробки електричною дугою складних за зовнішнім контуром деталей та запропоновано конструкцію електрода-інструмента, що дозволяє визначити запропонований спосіб, як високоефективну альтернативу традиційним технологіям. Purpose – to increase the technological capabilities of the process dimensional processing electric arc of difficult at the external contour of the parts. The work presents the described method and the electrode-tool for machining complex at the external contour of the parts in the implementation of the technological scheme of formation by direct pumping of the working fluid. The results of experimental research of the technological characteristics of the process of dimensional processing electric arc such as: the processing performance M mm3 /min, the roughness of the processed surface Ra μm, the relative linear wear of the electrode tool of Ȗ % and the side electrode gap į mm. Dimensional processing electric arc is the most effective of the known methods of processing complex at the external contour of parts and implements technological scheme of formation by direct pumping of the working fluid through the electrode-tool geometry of the working edge of which is built on the following parameters: inlet electrode gap provide uniform within the working fluid in the gap due to the inclination of the inner wall of the electrode tool within the Į – 0,5...1°, and from it on the working end surface provide a work belt (equation) within 3...5 mm. In addition to the working zone in the circumferential direction of the electrode-tool include the inclination ȕ - 3...5° that the steady flow of the working fluid in the electrode gap and the corresponding quality of the processed surface.Item Розмірна обробка електричною дугою отворів складного контуру(КНТУ, 2015) Носуленко, В. І.; Юр’єв, В. В.; Nosulenko, Viktor; Yuriev, VitalyРозроблено, теоретично та експериментально досліджено і описано технологічні схеми формоутворення розмірної обробки електричної дуги (РОД) листових деталей складного контуру згідно класифікатора та фізико-технологічні характеристики процесу, його гідродинаміка, конструкції електрода-інструмента (ЕІ), як високоефективну альтернативу традиційним технологіям. The article is devoted to the development and improvement in dimensional processing electric arc holes of challenging when pumping circuit through the electrode-tool and the workpiece. In work the analysis of the known methods of processing of complex contour holes and their shortcomings. Substantiated the technological scheme of forming holes of complex contour method dimensional processing electric arc. Were developed the structure of the electrodes and their relative linear wear A method dimensional processing electric arc for processing sheet metal parts of complex contour and electrode-tool, ensuring high quality treatment.
