Aberdeen CNC Machining, or Computer Numerical Control Machining in full, is the process through which computer-controlled programs are used to sharpen and hone specific machine parts to create a final piece that fits its specific application. The process is well known for its accuracy and precision. It is a subtractive process as it involves the removal of some parts of the workpiece. CNC machining, in Aberdeen or elsewhere in the UK, begins with the development of the first model using CAD (Computer-Aided Design).
