Offset Roughing
February 6, 2009 · Filed Under MeshCAM Development · 2 Comments
As I started working on the new conformal roughing a bit more I realized that some fundamental changes would be required. Starting from a clean slate I wrote a new offset algorithm to base the roughing on. Long time readers may remember that I’ve had a spent some time working on other offset algorithms. My last one worked well but it wasn’t as fast as I’d like and it always had the potential to fail since it depended heavily on floating point math (even though it didn’t in my testing). My new code is much more robust and generates much smoother toolpaths than the old roughing even though the code is only half done. It’s still far from done but I think the proof-of-concept below shows enough promise to commit to this approach for V3.
