ABSTRACT:
A cat-head type machine tool is controlled by an electronic control system (28, 31) so as to allow relative movement between the rotating tools (11, 12) and the stationary workpiece (22) within a revolution of the tools, such that non-uniform and/or barrelled or oval profiles may be machined on a cyclindrical workpiece. This is particularly useful for the high speed production of pistons for internal combustion engines where such profiles can give a piston improved performance.
