The full name of CNC is Computer numerical control. Computer numerical control (CNC) is a method for automating control of machine tools through the use of software embedded in a microcomputer attached to the tool. It is commonly used in manufacturing for machining metal and plastic parts. Computer Numerical Control – Taking digitized data, a computer and CAM program is used to control, automate, and monitor the movements of a machine. The machine can be a milling machine, lathe, router, welder, grinder, laser or waterjet cutter, sheet metal stamping machine, robot, or many other types of machines. This type of machining requires fewer machine operators since one skilled operator can run several machines at one time. Since the CNC is so accurate it reduces errors from the manufacturing process and eliminates unnecessary waste.

While pin terminals are used both in electrical & electronic systems, they find more use in electronic/communication systems.   An electronic system includes different electronic devices that are interconnected. This network of various components/circuits is connected using different interconnects.   An interconnect is a physical/logical connection between 2 electronic devices of networks. Interconnects of various types have been developed for varying purposes such as signal transmission, power distribution, and more. Based on termination ends, these interconnect have been classified into three:     1.       Board-to-board connectors 2..       Cable/wire-to-cable/wire connectors 3.       Cable/wire-to-board connectors     Board-to-board connectors: These connectors are mostly used for interconnecting PCBs without a cable. They save space on cables, hence making them suitable for systems with limited space irrespective of parallel & perpendicular configuration. Motherboard and daughterboard arrangements usually employ board-to-board connectors.   board-to-noard-connector Cable/wire-to-cable/wire connectors: As its name suggests, it connects two wires or cables. One end is connected to a permanent wire while the other end to a separable interface.  There are a lot of varieties of Cable/wire-to-cable/wire connectors in the market each serving different purposes.   cable/wire-to-cable/wire connector Cable/wire-to-board connectors: As its name suggests, Cable/wire-to-board connectors connect a wire to a PCB.  They are similar to the wire-to-wire connections, especially in the mating interface.   cable/wire-to-board connector Terminals give different meanings when used in different disciplines. From an electrical perspective, it simply means a point at which a conductor comes to an end whether it be a component, device, or network. The textbook definition of a terminal would be, a connecting joint at an endpoint, acting as a reusable interface and creating a point where external circuits can be connected. To locate it in a circuit you can look at it at the end of a wire probably fitted with a connector or a fastener.

CNC turning is a CNC process where a cutting tool, a typically non-rotating component of the lathe or turning center, removes material from a rotating rigid material. This process produces different shapes and sizes depending on the turning operations used. The first part of CNC turning is “CNC,” which stands for “computer numerical control” and is commonly associated with the automation of machining processes.   “Turning” is the machining term for a process where the workpiece is rotated while a single-point cutting tool removes material to match the final part design.   Therefore, CNC turning is an industrial machining process controlled by a computer and carried out on equipment capable of turning: a lathe or a turning center.  This process can take place with the axis of rotation in the horizontal or vertical orientation. The latter being used primarily for workpieces with a large radius relative to their length.

CNC stands for Computer Numerical Control milling. This essentially means that the milling machine is moved and monitored by numerical computer control, rather than by hand. CNC milling is a manufacturing process that uses a cutting tool mounted on a rotating spindle to selectively remove material from a raw substrate to get what we want. The workpiece is rigidly mounted on a table that moves or rotates in different planes, so the tool can work at multiple angles. Complex CNC milling machines can have 5 or more independent axes of motion to create more complex shapes or avoid moving the workpiece to a separate machine.
