The effectiveness of elastic polymer-abrasive wheels when rounding edges has been proved. The research showed the influence of cutting speed, deformation of the tool and feed along the edge on the quality of the machined edge and the productivity of the process. Empirical equations are proposed for calculating the parameters of quality and productivity depending on the processing regime parameters.

The thermal processes that occur during processing with elastic abrasive wheels (EAW) are analyzed. The calculation of heat from the impact of a single abrasive grain and the temperature of the billet during processing, which should be lower than the melting temperature of the EAW polymer binder, is proposed. The adequacy of the mathematical model is confirmed by experiments. Keywords: ELASTIC ABRASIVE WHEEL, MICRORELIEF, CUTTING FORCE, TEMPERATURE, PROCESSING MODE. Dimov-Ura@yandex.ru
