Revealing patterns in the wear of profile diamond wheels

Eastern-European Journal of Enterprise Technologies, 2020
Істотний вплив на точність обробки виробу і продуктивність процесу профільного шліфування надає електроерозійна правка круга.Для ефективного управління точністю обробки найбільш істотне значення має похибка, викликана зносом алмазного круга. Правку круга необхідно виробляти, коли знос підходить до границі, але не виходить за межі поля допуску.
