CNC Machining is a process used in manufacturing industry which involves using computers to control machine tools. CNC means Computer Numerical Control. The control machine tools can be lathes, mills, turning, routers and grinders. On the surface, CNC machining looks like a normal PC control machine, but computer’s unique control console and software are what really separate system for using in CNC machining. A computer program is customized for an object, G-code control feed rate, location, speed and coordination. With CNC machining, computers can control exact speed and positioning. First, create CAD drawing and code that CNC machine can understand. The program is loaded and operator test the program finally to ensure there has no problems. This trial run is called “cutting air”and it is an important step because any speed and tools position mistake will lead to damage machine or scrape the parts.
CNC machining is used in manufacturing plastic parts and metal and it has many advantages, it is more precise than hand machining, and can repeated again and again with same manner, produce complex three dimensional shapes. Because of these characteristics, CNC machining can used in repetitive tasks and jobs that need high precision. If you want to be a CNC machining operator, background in mathematics, mechanical drafting and computer usage will be useful for you.
