There are different kinds of cutting materials, and one of the most common is the CNC foam cutter. There are a number of different types of CNC foam cutters available for various industries, some of which can be purchased online, but there are some that can only be found at industrial supply stores.
Making your own is easy and affordable. It is probably the easiest way to make CNC foam cutter in the home workshop, with a couple of basic tools that you may already have lying around. The use of wood or cardboard can help to make a sturdy cut, but you can easily substitute with plastic, aluminum, or a standard cutting tool.
Purchase a construction sheet or metal blueprint. Cut the sheet into the size you want, and then place it inside a cardboard box or plastic bag. Keep this inside the case, so that it is dry. Cut the construction sheet to fit inside the case, and tape or staple it shut.
Place the construction sheet inside a paper roll, and take a piece of cardboard or plastic and cover the cardboard. Drill a hole on the cardboard, which will be your cutting surface. Use a hole saw, or something that will cut without damaging the cardboard. This can be a wire or wooden dowel to punch a pilot hole into.
When the hole is drilled, drill several holes that will be used for the guides for the cutting head. This is where the cutting will begin. Your form will be cut into strips, as long as your foam cutter is big enough to do it.
Now, once the cases are all cut, open the boxes that have been placed inside the case. Empty out the cut foam onto a flat surface, and then cut it as you would any other fiber board. Make sure that all sides are smooth and even before cutting.
Once all of the sections are cut and cleaned, put them into the cases and glue them together. They will form foam sealants that will hold the handles, as well as the door to keep moisture from seeping in. If you are using an old board for the foam door, make sure that it is a good plywood.
With a CNC foam cutter, you can cut any shape of foam that you wish. The main function of a CNC foam cutter is to cut foam, and is great for use inside items such as particle board and other foam.
