The analysis shows that one of the most rational ways to increase the efficiency of the grinding process is the choice of rational processing modes because, in this case, occur a comprehensive solution to the problem: first, the need to use expensive lubricant-cooling agent reduced, and second, the need for special grinding wheels and their frequent trueing was reduced. The structure of comprehensive theoretical and experimental studies of energy-power parameters for the technological processes was considered. A system of equations developed based on the hyperbola method was presented, which describes spatial fields of the velocities of particle displacements around the abrasive grain. The order of mathematical operations is expounded, which allows finding important physical quantities characterizing the chip material's deformed state. The deformed state of the cut layer is analyzed – the flow around abrasive grain during plunge grinding. The velocities and dislocation density fields were constructed for a specific example of processing. In the experimental part of the work, the research of the influence of technological regimes and the abrasive tool's characteristics on the quality of the hard-working materials' grinded surface was carried out. |
