What exactly is computer-numerical-controlled (CNC) machining
? Ití»s a means to make parts
by removing material via high-speed, precision robotic machines that use an array of cutting tools to create the final design. CNC machines
commonly used to create the geometric shapes required by customers are vertical milling machines, horizontal milling machines, and lathes.
To successfully make a part on a CNC machine, programs instruct the machine how it should move. The programmed instructions are encoded using computer-aided-manufacturing (CAM) software in conjunction with the computer-aided-design (CAD) model provided
by the customer. The CAD model is loaded into the CAM software and tool paths are created based on the required geometry of the manufactured part. After determining the tool paths, the CAM software creates machine code (G-code) that instructs the machine on how fast it should move, how fast to turn the stock and/or tool, and the location to move in a 5-axis coordinate system.
