Claim:
1. An incremental sheet forming apparatus comprising: a rod having a first end and a second end; a substantially curved surface on the first end in which the first end is configured to impinge a sheet of material to form a shape for a part; and a texture on at least a portion of the substantially curved surface on the first end, wherein the texture is configured to channel a lubricant onto the sheet of material; a platform configured to hold the sheet of material; a motion control system configured to control movement of the substantially curved surface to impinge the sheet of material to form the part; a lubrication system configured to supply the lubricant along an outer surface of the rod to the substantially curved surface while the substantially curved surface impinges the sheet of material; and wherein the lubricant on the substantially curved surface reduces undesired deformation of the sheet of material while the substantially curved surface impinges the sheet of material.
