CNC stands for Computer Numerical Control. In simple terms, this basically means the act of controlling machinery via a computer. A computer changes the design produced by Computer-Aided Design software into numbers. The numbers are similar to the coordinates in a graph to guide the pattern of the cutter. Using these coordinated the computer can cut the material to a specific pattern. This has many benefits; one being increased productivity. The machines can continue to run without needing to be controlled by a human. A CNC also has multiple axes so it can easily cut materials in a way that couldn’t be done manually. It works much faster than a human so lots of products can be made quickly and easily. CNC machines are also fairly safe. Once the programme has been set, humans are safely away from the operation, so risks are reduced. Although, of course, safety measures must be put into place at all times during use, such as goggles.
Purchasing a CNC machine is obviously expensive. It’s an investment that can be justified in the right environment. If your company uses it correctly, it will save money and increase efficiency. You’ll be able to complete products much more effectively. CNC machines are controlled by G-code. G-code uses G- and M-commands that have an assigned movement or action. In order to create this code, programmes such as Cura are used. This automates the process of writing, so the code doesn’t end up being pages long.
CNC machines use router bits which can be used for different materials such as wood, plastic and aluminium. Different types of bits have different types and speeds of carving. Usually, bits are designed for either speed or accuracy. Using the right bit can change the way things operate in your project. You can improve efficiency when creating a quality cut and make the job more precise. Using the wrong bit can result in damage so it’s important you get it right.
