Showing Off: Compressor and Turbine Blade Designs

I've spent way too much time in the last few months rebuilding my CNC mill with ballscrews, 4th axis, other upgrades, but I'm finally back in business
and ready to cut some sweet parts. I'll do a long post about the jet projects in progress, here's a sneak preview.

In about a page of Common Lisp, I nab the XY values for a NACA 2408 airfoil, scale it progressively from root to tip, twist it 25 degrees, and generate G-code to cut it using either the 4th axis or vertically top-down (or detecting that your blade profile can't be milled top-down).



Oh, and also serve up an HTTP interface to view the shape updates in real time using visjs.




More to come...
