I have written a VB software which computes coordinates of ellipso´dal wings then produces the Gcode (as txt files) of those coordinates needed to cut or mould the wings. One has to add the general instructions to its CNC router (feed, units used that is millimeter....). It does not take the size of the router bit into account. The profiles used are txt files from "profili".
I also have written a similar software to produce "Drela" type wings with a CNC router instead of a hot-wire machine.
Any body interested?
