METHOD OF ESTIMATION OF PROCESS EFFICIENCY OF LUBRICATING-COOLING LIQUID

摘要

FIELD: machine building.SUBSTANCE: invention relates to the machine building, in particular to testing of the lubricating-cooling liquids (LCL) used during metals cutting. Method of estimation of the process efficiency of the lubricating-cooling liquid (LCL) under which the actual friction coefficient with/without estimated LCL, maximum cooling rate of the temperature sensor in the tested LCL and in air (without LCL) from temperature in cutting zone to room temperature are measured for 10-20 s. Then coefficient of complex efficiency is calculated by equation:where Kis friction coefficient received using tested LCL; Kis friction coefficient received w/o LCL use; Vis cooling rate in air; Vis cooling rate received with tested LCL.EFFECT: significant decreasing of labour intensity and testing time of LCL efficiency at specified modes, and accounting of the lubricating and cooling action of LCL.5 dwg, 1 tbl
