Abstract

Surface integrity is an important factor under consideration for determining the machined surface quality for some critical applications, such as hot forging die and in mold making industry. In this study, the surface integrity of hardened H13 tool steel (HRC 50±3) was studied when end milling using P10 TiN coated carbide tools to reveal the effect of machining parameters and worn out tool on the machined surfaces. The machining parameters studied were cutting speed (224 m/min - 355 m/min), feed rate (0.1 mm/tooth - 0.25 mm/tooth) and depth of cut (0.3 mm-0.8 mm). The results show a good surface finish was achieved at low feed rate and high cutting speed combination. The machined surface topography is uniformly formed at 0.1 mm width of flank wear land, whereas at higher flank wear land the peaks and grooves are observed. The detailed microstructure analysis shows that worn out tools caused over heated of the machined surface and microstructure changes of the workmaterial. The width formation of microstructure changes, increases with the increase in wear land and feed rate.
