Abstract

Urgency of the research. The quality and accuracy layers surface of the part, in the first place, is determined by the parameters of the grinding operation. The cutting process, at grinding, is not performed by all the cutting grains of the working surface of the abrasive wheel, but only by those that are above the bunch. The effectiveness of the grinding process influences not only the cutting edge of abrasive grains, as well as wrought.Target setting. Finishing operations including grindings, are rather difficult non-stationary, thermal stress process. 3D modeling of cutting process of single abrasive grain allows investigating in detail the process and increase efficiency finishing details.Actual scientific researches and issues analysis. In the last researches was considered the method of determining the components of the cutting forces during grinding with crossed axes tool and details, method of deep single-pass grinding with the crossed axes tool and detail. Considered a methodological aspects of modeling cutting processes by method of final elements.Uninvestigated parts of general matters defining. Absence of design and research of cutting process by single abrasive grain at round deep grinding.The research objective. The purpose of this work is modeling of cutting process by single abrasive grain at round deep grinding.The statement of basic materials. Before beginning cutting process of abrasive grains a fairly long slip sliding of the cutting edge in the place of contact. This sliding is followed by plastic deformation of metal which occurs without shaving removal. Using appropriate software equipment may create a 3D model of cutting process single abrasive grain and determine the cutting force on this grain of abrasive tools.Conclusions. The first was created 3D model of cutting process a single abrasive grain during at round deep grinding and considered cutting force in the relevant points of abrasive grain. This model can be used for a research of cutting process by an end face, a transitional edge and the periphery of a grinding circle.
