Improvement of surface roughness of aluminum products by the micro-grooves on tool surface in cold extrusion
The effects of the micro-groove arrays formed on the tool surface on the material flow, surface condition of a billet and surface quality of a product were investigated by carrying out the plane strain extrusion experiments. Paraffinic mineral oil and RBD palm olein were applied in the above experim...
