Effect of lubrication in upsetting of aluminum alloy columns Kinji SATO* and Toshio YOKOYAMA* A concentric circular groove is on the both end surfaces of aluminum alloy column to retain lubricant. The columns are compressed by appling lubricant oozed from a groove and its barreling forms are measured. Effects of diameter and depth of concentric groove on the lubricating ability are studied in the compressibility of 10 to 40%. Effective geometric conditions of a groove are obtained from these
