Not every knows that it is possible to own a CNC machine and have it at home in your own workshop. CNC for beginners starts with investing in a machine, there being many companies that can supply you with a completed machine at a price you can afford. Alternatively, you may like to build your own CNC machine if you are feeling adventurous. Of course, the outcome of these two possibilities will never be as grand as a 7 axis machine that you find in the biggest CNC shops, but there again you will not need such high precision or speed when you are getting started with CNC.
CNC for Beginners : Getting Started
CNC is not as difficult as you may first presume, but it does involve learning some basic concepts as well as understanding the different tools and parts that you will need. Below are the basic CNC concepts that you need to know to get started, the first bringing about the question of what type of machine to build or buy. You can choose from routers, plasma cutters, milling machines, and even 3D printers; all of these fall within the field of CNC.
CNC for Beginners : Software
Once you have decided which type of machine to opt for, you will need to have some knowledge of the CNC software you will be using. Investing in a CNC dictionary can help you with terms you are uncertain of, dictionaries being available on line. Once you are familiar with the different terms used in CNC, it will be easier for you to understand which tools you will need for the machine of your choice. For example, if the machine of your choice is a CNC router cutter, you will need to understand the different types of cut. These include up and down cuts, straight flutes, compression cutters, and diamond cutters.
If your choice of machine is a CNC milling machine, you will need to familiarise yourself with milling vises, clamps, plates, and more. Routers will also use clamps, as well as vacuum tables and spoil boards. CNC lathes will use different methods from routers and milling machines, lathes being used in CNC turning.
Once familiar with the different types of machine, and the tools used with each type of machine, you will next need to familiarise yourself with what materials can be used best with the machine of your choice.
Perhaps the most daunting part of CNC for beginners is the learning of the G-Code that you will need in order to transform your chosen piece of metal, wood, or other material with your chosen machine into the end part you want to make. A CNC machine manual found online will provide you with the basics you need to learn G-Code. Remember, that this part of CNC will require studying, and that you cannot be expected to make complex precision parts the first time you put what you have learned into practice. Learning CNC can be fun, both online, and in workshops that you can locate in your hometown or at your local college. If you love experimenting and inventing things, then CNC could be for you.
