HISTORY OF CNC
CNC (Computer Numerical Control) machining refers to the process of manufacturing a part by the removal of material with a cutting tool that is under automated control as opposed to manual control by a machinist. This cutting tool can either be held stationary, with the part moving, or the tool can be rotated and moved into a piece of stationary material. CNC machining is often performed on metals but can also be employed with plastics and composites. CNC machining has revolutionized the manufacturing industry since it was first introduced in 1952 in the form of the Cincinnati Milacron Hydrotel. Since then, advanced robotics systems have been incorporated into the machines to dramatically improve productivity and ultimately reduce the labor requirements for the manufacturer of components. CNC (Computer Numerical Control) machining refers to a type of subtractive manufacturing that is designed for manufacturing a part automatically by either advancing a spinning cutting tool...
