What is a CNC Machine?
CNC stands for Computer Numeric Control. A CNC is an automated manufacturing technique that allows for fast, efficient and repetitive cutting, boring, drilling, machining and fabricating of material by computer-controlled devices. A CNC machine consists of a mini or micro computer that acts as a controller of the machine. All cutting processes are carried out by a range of complex machining tools that are directed by instructions fed into the computer.
Once a particular part has been designed and instructions for machining it have been written, a CNC machine is programmed with those instructions. Raw material is fed into the machine, the setup is completed and the computer does everything else: rotating the part, cutting off various layers, drilling holes to desired depths, even changing cutting bits automatically. Identical parts can be machined over and over, with little or no variance.
The basis of each CNC project is a 2D or 3D CAD drawing which is translated into computer code for the CNC machine to execute.Read More
