The purpose of the research work is to increase the productivity of roughing by dimensional electric arc of the guide roller of a small-section mill compared to traditional metalworking methods. The technology of processing the guide roller of a small-sized mill has been improved by using the dimensional arc machining (DAM) process. The relationship between the technological characteristics of the DAM process with the electrical and hydrodynamic processing modes and the geometric parameters of the outer side surface being processed has been revealed. Mathematical models of the technological characteristics of the DAM process of the guide roller of a small-sized mill have been obtained, which allow them to be predicted and the processing mode to be optimized. It has been shown that the roughness of the side surface after DAM of the workpiece mainly depends on the pressure of the working fluid in the gap and the strength of the technological current, and with an increase in the current strength, the roughness increases. The results obtained in the process of performing scientific and research work formed the basis of scientific and methodological recommendations for roughing with a dimensional electric arc of the guide roller of a small-gauge mill, which allows increasing the efficiency of roughing by 50% compared to mechanical processing.
