Abstract

Background. The object of research is the process of electric erosion forming of diamond abrasive wheels as well as the automation of the said process. The study is aimed at improving the productivity and decreasing the energy consumption of the process of electric erosion machining on the basis of extreme combined control.
Materials and methods. The authors used the methods of the modern theory of automatic control and automation of technological processes, the probability and mathematical statistics theory, computer modeling.
Results. A synthesized extreme combined system of control of the electric erosion forming of diamond abrasive wheels allows increasing of the said process productivity and decreasing its energy consumption.
Conclusions. The research, conducted on mathematical models, showed that the application of the extreme combined control of electric erosion forming enables increasing the stability of the process by 18 %, extremum maintenance accuracy − by 16 %, productivity − by 20 %, and decreasing energy consumption by 10 %. 

Key words

electric erosion processing, extreme response, extremum-seeking algorithm, least squares method.
