I am new to the world of CNC. I just finshed building a cheap machine the 7th Sojourn. I have been trying to cut out balsa wing ribs but having diffuculty with the arc and formula. Can someone offer help.
Are you drawing the part and using a CAM program to create the g code? You can get dwg files of airfoils that you can scale to fit the plane your using it for.
