Description: This is a very fast run through the stages involved in creating a prototype model plane wing using a CNC router to cut the parts from a sheet of Balsa. 1) First the parts are designed using Google Sketchup 2) Next the CAD files are imported into Vectric Cut2D and G-Code for the CNC router is created 3) The router cuts the parts 4) Assembly and finishing All up this process took several hours, but that was partly because I hadn't tackled this type of project before. I anticipate that the next time I tackle a similar project I should be able to complete it in less than 3 hours... The parts were cut using a 1/32" 2 flute end-mill at 36,000RPM & 160IPM feed-rate. The finished wing weighs in at 15 grams, the last slide shows it supporting 453 grams which is just over 30 times it's own weight! Pretty strong. This wing is actually a 1/2 scale prototype for a larger wing that will have a 32" span. The main reason for the smaller prototype was to test the entire process before using up more materials on the real thing.
