Cut wood and carbon fiber parts with a CNC

posted in: Machining Projects | 0

This post I wanted to dedicate to other work to do with this machine. With a thin tool can cut sheets of any non-metallic material, achieving precise pieces in a very quick manner.
The first thing I could think was to cut a wooden structure, 5mm plywood with a single lip cutter 3mm diameter. The CAM programming process is really easy, because with a contouring operation in CATIA and go selecting the lines one by one, you’re done. Later I have been learning to use other CAM programs such as Vectric Aspire, for these things really are much more agile. 

As you can see, after mounting is done without more difficulty, of course is really the merit of CAD work. I would advise to do this kind of testing parts, since adjusting certain tolerances, further work can be avoided. When a piece needs to fit within a housing, always sanding to finish the setting. By testing can determine that excess must be given to the hole for example, or the piece that goes inside, ie the clearance to avoid sanding later, and that is simply milling, and mounting. This can be done, as do some tests, put into practice and will hang here
These jobs have enormous practical application, because it can be combined with some programs that generate 3D volumes by a system of ribs. For example, Autodesk has released a set of programs called 123D, and I emphasize the 123d Make

Imagine the possibilities of any 3D we generate, we can obtain the skeleton-based or volume of any geometry.
But the chances of this technique not only end here. There is a fairly wide range in the world of radio control hobby
For example, the RC model airplane

These images are just examples that I found online model airplane fuselages. But they are perfectly simple manufacturable with CNC.

You see, the first step would be to generate the 3D model of the surface of the fuselage, but it’s something that today can quite easily get Internet as there are many free models out there. In this geometry, it is relatively easy to draw the “ribs” of the plane, of course it takes some knowledge of aeronautics, but for someone who knows, or simply copying other aircraft concepts seems a feasible task, or at least possible.

And with a router this can be done using this type of machining, having no limits when trying to make something.

Another example would be the application of RC cars. The chassis of these cars are a very important element, since they require ruggedness, toughness and versatility. Generally consist of a flat plate with a specific geometry, to mount all components.
These images are also samples for Internet radio controlled chassis in carbon fiber. simply awesome

Being a flat piece, we can also manufacture it with this type of machining. Now, to be trendy, good chassis should be carbon fiber. Today, the Internet can get plates made of pre-impregnated carbon fiber, oven cured and quality standards at competitive prices. If we get one, we can design and build our own carbon fiber chassis for a car.
For machining carbon, while cutting conditions are not complicated, you need a special tool, because carbon has the distinction of being tremendously abrasive. A high speed steel cutter, you can take just over half an hour cutting carbon. So you have to have special strawberries, which of course are more expensive. I got a diamond-coated tool, especially for cutting carbon Ø3mm, I hope I last a long time, because it cost more than 50 € …

My idea with this post is show first the capabilities of what you can really do with these little machines, and perhaps encourage people to be manufactured one. Or of course, if I had a project that required cutting or machining, you can of course get in contact with me. I will be happy to help you to develop your projects in both CAD and CAM.
