Long bar member machining apparatus and method
 In the case where a product having a free-curved surface is obtained, a machining work is performed by separate machine tools. Therefore, works of attaching and removing a half-machined product are necessary. Consequently, a lot of working time and labor are required. Also in an automatic production system, productivity is lowered if the system is stopped by failure in gripping during the attaching and removing works and an enormous equipment cost is required. A machining apparatus M comprises a main chuck head 1 having a control axis for holding and rotating a long bar member W, a head stock assembly 3 having three or more control axes, and a bar member feeder 5 for feeding the long bar member W to the head stock assembly 3. These four axes are simultaneously controlled to manufacture a plurality of products V having free-curved surfaces from the long bar member W. By the machining apparatus M, the products V having free-curved surfaces can be obtained from the long bar member W which is fed by the bar member feeder 5.
