CNC stands for Computer Numerical Control, which is a way of automating machines that normally require human interaction. This can be anything from robots to milling machines and lathes. CNC services allow us to mass produce goods with precision. However, there are consequences, since it limits the artistry behind everything we make.
CNC machining techniques evolved from milling machines to lathes, 3D-printers, and more. In this article, I will discuss what you make with a CNC machine by going over a few different topics: material types, their uses, and the range of imaginable projects for a CNC machine.
Some Materials Used with a CNC Machine
Wood
Wood is one of the most common materials to use when milling with a CNC machine. It is easy to work with, and it provides good material for intricate projects. The best part about working with wood is that you find this material for basically free. Many people throw away or sell scrap wood because it is broken or damaged. You find this wood, oftentimes, for just the price of waste disposal.
When using CNC machines to mill out projects in wood, you are limited to cutting shapes that are much larger than the machine itself. This means that all the pieces needed for an intricate and detailed project join together to make a single large piece. This process is nesting, and it is extremely important when milling out projects in wood with CNC machines.
Metal
Fabrication is a popular use of CNC machines. It is so widespread, in fact, that it is difficult to find scrap metal pieces. This is because people started using CNC technologies to cut out the shapes they need instead of just scrapping old items and parts. You find metal for free by searching around your local junkyard or roadside dumpster. Call ahead and see if they allow you to take pieces home.
PVC
Like metal, cutting out large pieces of PVC pipe is easy to do with a CNC machine. You find free pieces of PVC pipe anywhere that sells plumbing supplies. However, if you have trouble finding the right size or if you need something different, Amazon also offers pre-cut pieces. To make some custom cutting boards, this is the best method.
What a CNC Machine Makes
Because they require very little human input, CNC machines do many things. It is one way to create custom metal pieces for furniture or accessories made from brass, aluminum, stainless steel ,and other metals. They are programmable with any design, allowing you to have exactly what you want in your home or business. If you imagine it, it is possible make it with the help of a CNC machine.
Laser Engraving and Cutting
A laser engraver or cutter allows you to etch designs into glass, marble, stone, and other materials. It is possible to use this process on wood as well, but do it separately. This is because the wood burning process causes problems when trying to etch the design onto glass or marble.
This process has a variety of purposes, such as creating logos, personalizing awards, and much more. In addition, medical facilities use the process to cut out life-size anatomical materials that mimic skin tissue and organs for medical training environments.
Car Manufacturing
CNC machines are crucial aspects of modern car manufacturing. They drill holes, cut metal, and shape the products to perfection. As a result, they fit together seamlessly.
Sculpting
CNC machines create sculptural works of art. The detail, precision, and accuracy of the cutting process ensure that the end result is perfect. This makes it a popular choice for artists looking to make identical pieces or large ornamental sculptures that are difficult to produce by hand.
Woodworking
CNC machines excel at cutting wood. This makes it a popular choice in a typical woodworking business for making picture frames, kitchen cabinets, and sculptures. These machines also carve the top of wooden tables into fancy designs that a human hand is unable to do.
Conclusion
There is a large range of things to make with a CNC machine, from household items such as door handles to more complicated pieces that require welding or soldering like bike parts.
Hopefully, this list gives you some inspiration for what you can make. Thanks for reading!
