The effect of acrylic resin impregnation on roachinability of sintered alloy steel for an engine valve seat was studied in turning operation. Flank wear of a carbide tool was decreased by acrylic resin impregnation in turning sintered alloy steel, and the scattering of tool life was also improved. As cutting speed was decreased, the effect of resin impregnation on improvement of tool life was considerable. Tangential and vertical forces increased as flank wear developed. On the assumption that an increase in cutting force was due to friction force on the flank face, the coefficient of friction on the flank face was estimated. As a result, it is inferred that the coefficient of friction on the flank face was decreased by resin impregnation. This effect caused a reduction of heat generation on the flank face.
