If you want to know how to programme a CNC machine then chances are that you are interested in a career in CNC. Or perhaps you want to take up machining as a hobby. Whichever your case is, the simplest way to learn how to programme a CNC Machine is by practicing. If getting a job at a machine shop is not realistic, then you can join forums, ask questions to machinists and programmers, and read up online.
If you are stuck in a job as a basic machinist and want to move onto a higher level, then reading up on CNC machining in your spare time could be your route to success. It should be noted that learning how to programme a CNC machine and how to use one are two different tasks. If you are a novice at CNC then you will need to learn how to programme a machine and also how to use a machine. Modern CNC machines need very little human assistance; if you are taking up machining as a hobby then you will of course need to learn both and about safety as well.
How to Programme a CNC Machine : Getting your Machine to Move
Getting your machine to move is easy once you have mastered G Code. G Code is necessary to tell your machine the way you want it to move. You can programme your machine to move in a straight line or a circle as well as programming the speed at which it moves. In theory this may seem quite simple. But in practice things get more complicated when you have to calculate the intersection of lines and codes. Here you will need to learn a whole load more codes ( CAD/CAM and/or macros)
Learning CAM requires basic computer knowledge. Even if you have no knowledge at all it is possible to learn. There are thousands of tutorials circulating on the web. YouTube is an excellent place to start.
Once you are confident that you have grasped the basics, you need to move on to actually machining a part. If you are a hobbyist then you will need to invest in a machine. A simple 2 or 3 axis machine is perfect for learning.
Knowing what tools to use and what speed and strategy is something that comes with practiced when learning how to programme a CNC machine. If you a machine, then practice simple cuts and movements; if you are still unable to afford a machine then scour your local college and workshops for places that will allow you to join and practice your skill.
Learning how to programme a CNC machine should not be an arduous task. It should be fun. Learn simple moves and cuts first, and don’t get annoyed if you make mistakes. Practice makes perfect, and once you are confident at handling and programming a CNC machining then is the time to switch careers and look for a job within the CNC industry!
