Woodworkers, whether they are hobbyists or professionals, would cost a major factor in updating their manufacturing systems. Repair could also be expensive. Even if CNC machines avoid man-made mistakes, it does not mean that they are completely perfect. Errors and problems could still happen. Even if there are disadvantages, it is clear that the benefits are still greater than the downside. Standard manufacturing concepts stated that machines should be operating at all times for maximum efficiency. That mindset was changed when the router they purchased became operational and produced in a few hours what their employees took two days to make. Commitment and patience, and not just a leap of faith, are certainly needed for a small shop owner when trying to upgrade his business. How does it relate to woodworking and its work processes like machining, for instance? CNC means Computer Numerical Control, a method used in modern woodworking and other production work where a computer program controls the action of the machines used in all the work aspects. CNC Machining It is the general term used on work processes that use machines to perform tasks that require high accuracy, precision, efficiency and are mostly repetitive in nature. Benefits The biggest benefit CNC machines have is their being able to make parts and pieces to the exact specifications programmed into its computer. This greatly helps lighten up human fatigue caused by common human errors on projects done manually in the old traditional ways. With no human intervention in the process (except in the pre-programming), the manufactured parts are made in exactly the same way each time. Aside from the actual software for CNC training, there is also a simulation software which could be used while training operators. This would help build your confidence and at the same time have some hands-on experience. There are trainings and programming systems developed for the past years that try to copy or simulate CNC software systems. At Home: Hobby CNC Woodworking Machine A homemade CNC woodworking router is often referred to as hobby CNC routers. These homemade CNC woodworking machines are usually based on plans which can be bought or downloaded. They are unique, since this would be based on the person who would build and use them, their needs and budget.
