CNC Foam Cutter
CNC Foam Cutters are an interesting type of CNC Machine. They generally show up with Remote Control Hobbyists or Model Makers. RC Hobbyists use them when building unique planes and wings. Model Makers use them for architectural mock-ups of buildings. CNC Foam Cutters are suited for both jobs quite well.
CNC Foam cutters make quick work of the foam. They cut fast and accurately. Most often they use some sort of hot wire cutting mechanism that slices through the foam. The CNC Programming aspect is similar to plasma cutting. You start out with a sheet of foam and direct the wire cutter along a specific cut path.
