METHOD OF DETERMINING COEFFICIENT OF UTILIZATION OF ABRASIVE GRAINS

摘要

mechanical engineering; grinding tools. SUBSTANCE: invention is aimed at providing optimum structure and rational operation of grinding tools. Coefficient is determined after grinding of workpiece and attaining of wear of grinding wheel which requires dressing of wheel. Coefficient is determined as ratio of summary number of dents on working surface of grinding wheel in form of cone-shaped craters located on places of removed abrasive grains to total number of dents in form of craters left by removed abrasive grains on the same section of the same area of grinding wheel surface. EFFECT: provision of trust worthy coefficient of utilization, reduced labour input in calculating. 1 ex, 1 dwg
