REGULATION OF THERMAL PROCESSES DURING ELECTROEROSIVE GRINDING WITH VARIABLE ELECTRODE POLARITY

The temperature regime during electroerosive grinding with periodic change of electrode polarity was studied. Special attention is given to the analysis of thermal phenomena occurring in the cutting zone and their impact on the quality of the machined surface. Using the Thirdwavesys graphical environment, process modeling was conducted, allowing for the creation of a simulation model that considers the influence of thermal impulses on the active resistance of the interelectrode gap and the parameters of electrodischarge impulses. Experimental studies have shown that electrical processes in the interelectrode gap exhibit an oscillatory nature, affecting the thermal regime. The obtained results allowed for the development of a mathematical model that accurately reflects the real electrical processes occurring in the cutting zone. This ensures more precise prediction of the behavior of the cutting tool and the machined material, enhancing the efficiency and quality of the electroerosive grinding process. Overall, the research confirms the importance of temperature control to achieve stable machining quality and minimize thermal deformations. The conclusions of this work will contribute to the further development of electroerosive grinding technologies and their application in the industry for machining high–quality parts from hard–to–machine materials.
