A CNC metal lathe with the door open. In machining, numerical control, also called computer numerical control (CNC), [1] is the automated control of tools by means of a computer. It is used to operate tools such as drills, lathes, mills, grinders, routers and 3D printers. CNC transforms a piece of material (metal, plastic, wood, ceramic, stone ...
Milling is the process of machining using rotary cutters to remove material [1] by advancing a cutter into a workpiece. This may be done by varying directions [2] on one or several axes, cutter head speed, and pressure. [3] Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy ...
The history of numerical control (NC) began when the automation of machine tools first incorporated concepts of abstractly programmable logic, and it continues today with the ongoing evolution of computer numerical control (CNC) technology. The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with ...
Machining. CNC machine pouring coolant to keep the tool and parts from getting hot. Lathe machine. Machining is a manufacturing process where a desired shape or part is created using the controlled removal of material, most often metal, from a larger piece of raw material by cutting. Machining is a form of subtractive manufacturing, [1] which ...
Computer-aided manufacturing. CAD model and CNC machined part. Computer-aided manufacturing (CAM) also known as computer-aided modeling or computer-aided machining[1][2][3] is the use of software to control machine tools in the manufacturing of work pieces. [4][5][6][7][8] This is not the only definition for CAM, but it is the most common. [4]
A computer numerical control (CNC) router is a computer-controlled cutting machine which typically mounts a hand-held router as a spindle which is used for cutting various materials, such as wood, composites, metals, plastics, glass, and foams. CNC routers can perform the tasks of many carpentry shop machines such as the panel saw, the spindle ...
Working from engineering drawings developed by the toolmaker, engineers or technologists, tool makers lay out the design on the raw material (usually metal), then cut it to size and shape using manually controlled machine tools (such as lathes, milling machines, grinding machines, and jig grinders), power tools (such as die grinders and rotary tools), and hand tools (such as files and honing ...
Multiaxis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting. This type of machining was originally performed mechanically on large complex machines.
