Abstract

The present research concerns study of the effects of micro-pits arrays formed on the taper die by experimental verification using. A series of taper die with micro-pits with different location at existence of die were design. A taper without micro-pits was used as a reference. The lubricant is additive free paraffinic mineral oil. P2 is a low viscosity lubricant while P3 is a high viscosity lubricant. The experimental results are focusing on the extrusion load, billet surface roughness, and grid pattern observation. From the result, the micro-pits array affected on surface roughness if the lubricant viscosity is higher but the extrusion load also become higher.
