RESEARCHES REGARDING THEORETICAL AND EXPERIMENTAL MODELING OF ELECTROEROSION PROCESSING OF THREADS IN SINTERISED METALLIC CARBIDES

摘要

One of the main axes of contemporary technological development is the use of electrotechnologies on an increasing scale. Within these, the electroerosion carries a significant weight because of technological advantages it presents in the processing of hard and superhard materials. In this paper, the authors present some of the results of theoretical and experimental research on the processing of inner threads with grooved copper electrode in sintered metallic carbides G20. These results are primarily concerned with the influence of electrotechnological parameters on thread pitch p and thread flank angle α. For these two geometrical parameters, in this paper are established the machinability functions that are useful for determining the processing parameters of threads by electroerosion.
