Abstract
A method for manufacturing a leg of a chair includes step 1 for preparing a metal ingot; step 2 for bending the metal ingot to be a V-shaped member; step 3 for forging the V-shaped member to have recesses defined therein; step 4 for removing the flash from the V-shaped member; step 5 for applying a first heat treatment process; step 6 for adjusting the V-shaped member precisely and step 7 for applying a second heat treatment process to the V-shaped member in step 6.
