Abstract: A milling machine includes a bi-directional, variable speed, rotary workpiece-holding table, a table drive sized to achieve relatively high acceleration and deceleration rates, a cutting tool mounted to a single or dual axis head, and a control system adapted to achieve a high degree of tool position and table rotational position accuracy cooperating to permit high-speed machining operations, including substantially dome-shaped parts characterized by circumferential surface portions interruped by radial wall portions. A dual table drive and interchangeable head arrangement make the machine also suitable for conventional turret lathe operations.
