How to Create Foam Models Using a CNC Router
by：QY Precision 2020-07-18
Companies are using CNC hot wire foam cutters to cut any 2D foam shapes that only requires flat surface. If there's a need to make a 3D shape, a CNC Router needs to double. A CNC router will machine any 3D shape. That a 3-axis machine, meaning that it moves in a 3D space diagonally or in curves, in motions that resemble milling or carving. The router can create 3D designs from numerous types of material, including: EPS foam, urethane foam, aluminum, light wood, acrylics, plastics and polycarbonate, Muscular tissues. The machining process involves creating 3D model using 3D CAD software, then bringing this model into a 3D tool-path that will tell the router the shape size, the resolution, cutting directions, cutting depth, and the like. The shapes that could be created with a router are almost unlimited. Applications & Industries: * Automotive - Full scale cars, boats, planes * Aerospace - UAVs models * Architectural - Any 3D architectural shapes * Fine Art, sculptures, statues * Marine - Boats, ships models * Museums - 3D displays, faces, statues * Navigation - Topographic maps If possess to a 3D model you'll want to design and it is either too big or too thick staying machined considering height or cutter length restrictions or the foam material not being thick enough, the shape can be sliced into sections. Each slice end up being machined separately using the router right after which the pieces can be glued alongside. The machined parts may be sanded and coated with protective hard shell and painted, which may take proper eliminating any visible grooves due to the gluing. Routers can be used moves molds which may later be poured with concrete or polyurethane and also other casting things. CNC routers range between a few inches of working area all during up to 50 feet in amount of time. Every router uses a spindle - it is the motor for doing real cutting. Router's spindles vary from 1HP (horse power) to 20HP and above, plus can hold end mills (the driller) from 1/16' all during to 2' and above. Different materials require different end mills and different cutting data transfer speeds. The denser the material the slower the cutting speed. If need to have to create a foam shape design with regard to large and also full scale you make use of a small model, scan it any three dimensional scanner then transport it into the CNC router for machining, using an area of expertise cutting software that generates the part file. Making use of the scanner allows you to convert any regular model using a live-size decor. Any model can be scanned - a face, a sculpture, a car toy, train, boat, plain and anything you need larger. You do not in order to be visualize and imagine a new 3D model will appear to be - the scanner this for owners.
