Method of determining the parameters of roughness on CNC milling machines AT roughing and finishing METAL prefabricated multiblade carbide tools UNDER face milling

摘要

FIELD: process engineering.;SUBSTANCE: proposed method comprises using of cutting parameters and tool geometrical parameters. To up precision of roughness determination trial cut is performed by composite multi-blade carbide tool at the part to measure thermal emf of every cutting tool tip. Mean arithmetic thermal emf of said multi-blade carbide tool is calculated. Roughness parameter R_â using the calculated mean arithmetic thermal emf, geometrical parameters of carbide tool and machined part are determined by enclosed formula.;EFFECT: higher precision of roughness determination.;7 tbl
