Показано переваги розмірної обробки електричною дугою (РОД) порівняно з традиційними
способами металообробки. Описано енергетичні характеристики електричної дуги в умовах РОД для
різних типів оброблюваних матеріалів. Purpose of the article - the analysis of possibilities of an electric arc as instrument for modern
manufacture.
The article analyzes the influence of the basic technical characteristics on process dimensional
processing electric arc on power performances of the arc column, and also its anode and cathode area is carried
out. It allows to judge efficiency of use of energy at handling of electrowire materials of a variety electrodesinstrumen,
both on a straight line, and on inverse polarity of electrodes. It is shown that the arc in the course of
handling changes its energy characteristics from maximum to minimum values of voltage and a technological
current, thus for an estimation of influence of these performances it is necessary to consider their average value
on time.
It is shown the basic advantages of the method of dimensional handling by an electric arc over
traditional methods of a metal working that allows to speak about economic feasibility of its application in the
conditions of modern manufacture.
