What G-Code interpreters will interpret/execute the 'few lines of NURBS
G-Code' to actually produce the part. Am I not right in thinking, that until
the controllers handle it, you'll still be stuck with your huge files?

|NURBS stands for Non Uniform Rational B-Splines. It is a way of
|discribing a complex curve by math equations. Simular to splines.
|

|NURBS interpreters (CAD/CAM) will allow you to draw those artistics
|shapes and import the math equation directly into the machine
|controller. It is then up to the controller to calculate the cutter
|path. It only takes a handful of lines of NURBS G-Code to describe a
|complex free flowing curve. There are two advantages to this, you are
|able to machine the exact shape you drew, and the post files come out
|of the CAD/ CAM with a 60-90% reduction in size.
|
|If you have ever milled a curve consisting of lots of small segments
|you know how taxing it can be on your machine. The surface finish
|also suffers from these small jerky movements.
