Abstract
OKUMA heralded in the industry and developed high-speed contour machining technology to control high-accuracy, high-quality and high-speed machining in shape machining as represented by die mold machining. In 1987,the technology was loaded into our company's computer numerical control "OSP". Since then, our company has developed and supplied a series of advanced control functions one after another prior to the needs of a market. OKUMA has developed the new high-speed contour machining technology "super-NURBS" which is based on technologies cultivated for many years. The new control technology "Super-NURBS" always pulls out the highest acceleration and deceleration performance of a machine also in curved surface machining. With this, "Super-NURBS" improves the machined accuracy and quality as well as reducing the machining time sharply (conventional ratio of our company twice). The following describes the abstracts and effects of new numerical control technology "Super-NURBS".
