Abstract

There is provided a metalworking process, such as for example a punching process, wherein a shaping tool (eg. punch) contacts and applies a non-chip forming shaping force to a metallic workpiece (eg. blank) and there is supplied to the interface between the shaping tool and the metallic workpiece an aqueous fluid composition, having an alkaline pH, comprising water, a tall oil fatty acid, sulfurized lard oil, a sulfurized olefin, an oxyethylene/oxypropylene random or block copolymer diol having an average molecular weight in the range of from about 1000 to 8000 and an organic phosphate ester such as for example poly (1,2-ethanediyl) alpha-isodecyl-omega hydroxy phosphate. Reduced forces, lower friction and improved tool life are observed.
