METHOD OF ACCELERATED DETERMINATION OF OPTIMUM CUTTING SPEED

摘要

FIELD: process engineering. ^ SUBSTANCE: proposed method relates to carbide plate-like cutting tool of application group P. First, temperature in contact between tool and machined material zone is measured at different cutting speeds to plot temperature to speed relation. Then said plotted relation is used to set optimum cutting speed whereat temperature in aforesaid zone corresponds to that of preheating carbide cutting plate in dilatometer cell corresponding whereat thermal expansion factor reaches its maximum. ^ EFFECT: higher accuracy of determination. ^ 3 dwg
