Abstract

Kohji, ONO;Tsutomu, SHIMAMUNE;Teruhisa, YAMAMOTOIn order to account for the effects of mechanical cutting action and electrochemical dissolution on the peripheral electrolytic grinding process, the removing mechanism of work material is theoretically analysed. And also, the influence of operating conditions on the mechanism is investigated experimentally. The following results are clarified.(1) There exist two parts of region in the electrolytic grinding contact zone; the one is the co-operative region of mechanical cutting and chemical dissolution, and the other is the region of the pure chemical electrolysis.(2) The position of boundary line of the above two regions varies with the operating condition in electrolytic grinding. The boundary depth of cut, that is the height from the bottom of grinding wheel to the boundary line, decreases at the inverse square of the work feed rate and does not depend on the setting depth of cut.(3) The boundary depth of cut above mentioned plays an important role in electrolytic grinding process. The amount of over-cut, the chemical proportion of material removed and Faraday's current in the electrolytic grinding can be derived theoretically using the boundary depth of cut as an intermediary parameter.
