    Електродугове фрезерування
    (КНТУ, 2015) Боков, В. М.; Bokov, Viktor
    Запропоновано та досліджено спосіб електродугового фрезерування, зокрема пазів. Обґрунтовано технологічну схему формоутворення. Отримано математичні моделі технологічних характеристик, які дозволяють керувати процесом та прогнозувати його. The objective of the work is reasoning of technological pattern for shaping grooves by electric arc and prognostication for technological properties of electric-arc milling. The work shows the results of electric-arc groove milling research: - analysis and research of different technological patterns of shaping grooves; - designing of graphite electrode tool of composite structure which ensures working liquid pumping through a narrow parallel-plate duct; - mathematical modeling of technological properties of electric-arc milling. Conclusions. There has been offered a method of cavity working, grooves in particular, by electric-arc milling. There was given experimental reasoning for technological pattern of groove shaping by electric arc with use of graphite electrode tool of composite structure. There have been received mathematical models of technological properties of groove electric-arc milling which enable to control and forecast them.
