Is this the world`s fastest CNC?

GE Fanuc says it has developed the world`s fastest CNC controller, capable of controlling the largest number of axes. The company`s Series 30i controller, unveiled at the recent EMO show in Milan, can supervise up to 40 axes - 24 of them simultaneously - and can execute up to ten different CNC programs at a time.

The controller, which uses a new high-speed processor, takes 25ns to perform ladder program steps, and can execute three ladder programs simultaneously. It provides nanometre interpolation and is said to deliver interpolation cycle times eight times faster than earlier models. It has a 1,000-block look-ahead for accurate contour control, and takes 0.4ms to process a block.

GE Fanuc expects the new controller to be used for high-end machines - such as five-axis milling machines and those using linear motors -- that demand high-speed, multi-axis, multi-path, controls. It could help to produce high-quality finishes on complex die moulds, minimising the need for polishing after cutting.
