Mechanical Strength of Abrasive Segment Formed by the High-Frequency Discretization of Grinding Wheel

摘要

Geometrical characteristics of a discrete grinding wheel, which influence on a mechanical strength of the segments, formed during a high-frequency discretization of the cutting surface by highly concentrated energy flow, were defined. The analytical dependences, which establish interrelation of actual stresses in dangerous sections of a discrete grinding instrument with geometrical and mechanical characteristics of a segment, were determined. On a base of these analytical dependences a designing of a discrete grinding wheel with highly frequency discretization of a cutting surface is executed. The scientific recommendations for choice of dimensional characteristics of discrete cutting surface were proposed. Observance of these recommendations allows getting the abrasive segments with a high mechanical strength.
