Computer Numerical Control, commonly called CNC

CNC is the automated control of machining tools (drills, boring tools, lathes) and 3D printers using a computer.  A CNC machine processes a piece of material (metal, plastic, wood, ceramic, or composite) to meet specifications by following a coded, programmed instruction and without a manual operator.
A CNC machine is a motorized tool and often platform that is maneuverable, which are both controlled by a computer, according to specific input instructions.  The Instructions are delivered to a CNC machine in the form of a sequential program of machine control instructions such as G-code and then executed. A person writes the program code or, far more often, the program is generated by graphical computer-aided design (CAD) software.  In the case of 3D printers, parts to be printed are “sliced” before the instructions (or the program) is generated.  3D printers also use G-Code.

Also known as a water jet or waterjet, is an industrial tool capable of cutting a wide variety of materials using a very high-pressure jet of water, or a mixture of water and an abrasive substance. The term abrasive jet refers specifically to the use of a mixture of water and abrasive to cut hard materials such as metal or granite, while the terms pure waterjet and water-only cutting refer to waterjet cutting without the use of added abrasives, often used for softer materials such as wood or rubber.[1]
Waterjet cutting is often used during the fabrication of machine parts. It is the preferred method when the materials being cut are sensitive to the high temperatures generated by other methods. Waterjet cutting is used in various industries, including mining and aerospace, for cutting, shaping, and reaming.

Is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, drum hardware, automobile, motorcycle, and bicycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods. The powder coating process was invented around 1945 by Daniel Gustin US Patent 2538562.
