OKUMA Technology SUPER-NURBS

OKUMA Technology SUPER-NURBS
Example with Super-Nurbs

Though Super-NURBS sounds 21st century, the concept actually dates back to the middle of the previous one. Initially developed as a mathematical way to regenerate freeform curves and shapes (think car bodies and ship hulls), in manufacturing, it’s now utilized in most CAD software packages, along with CAM systems.

The “NURBS” part of Super-NURBS stands for Non-Uniform Rational Basis Spline, but we added the “super” to ours because it adds a higher degree of accuracy when the surface being machined has complex shapes or large changes of diameter within a short linear distance. With Super-NURBS, it all comes down to controlling—and really, shortening—the feedback loop. 

The OSP control projects a predetermined tolerance band that creates a spline considered to be the best fit for the job. This eliminates redundancies and allows for a smoother tool path. With less data to crunch, movements are sped up—but the highest level of accuracy is maintained to create quality surface finishes.

The Super-NURBS Difference

  • Adds a higher degree of accuracy for surfaces with complex shapes or large changes of diameter within a short linear distance
  • Eliminates redundancies, which allows for a smoother and swifter tool path
  • Guarantees high machining accuracy and finish quality in half the time it takes conventional technology
  • Grants a greater level of control—and effectively shortening—the feedback loop
  • Increases throughput since raw stock is processed in shorter timeframes
  • Potentially eliminates the long and costly step of hand finishing, polishing or grinding structure. Performance and security for your business.
