The abbreviation CNC stands for Laptop Numerical Control, and refers especially to the computer “controller” of that reads the G-code instructions and drives the machine tool.
CNC was developed in the late 1940s and early 1950s by the MIT Servomechanisms Laboratory. CNC was preceded by NC (Numerically Controlled) machines, which did the exact same job of interpreting G-code recorded on Punched tape into motions of the machine making use of a electronic hardware. The initial CNCs utilized NC hardware, and the laptop was utilized for the tool compensation calculations and occasionally for editing.
Punched tape continued to be employed as a medium for transferring G-codes into the controller for numerous decades right after 1950, until it was sooner or later superseded by RS232 cables, floppy disks, and ultimately normal personal computer network cables. The files containing the G-codes that are interpreted by the controller are nevertheless known as “tape files”.
The introduction of CNC machines radically changed the manufacturing sector. Curves are as simple to reduce as straight lines, complex 3-D structures are relatively easy to make, and the number of machining actions that essential human action have been substantially reduced.
With the elevated automation of manufacturing processes with CNC machining, considerable improvements in consistency and quality have been accomplished. CNC automation decreased the frequency of errors and provided CNC operators with time to perform additional tasks. CNC automation also enables for far more flexibility in the way components are held in the manufacturing approach and the time necessary to change the machine to produce different elements.
In a production atmosphere, a series of CNC machines may possibly be combined into 1 station, commonly known as a “cell”, to progressively machine a component requiring a number of operations. CNC machines these days are controlled straight from files created by CAM software packages, so that a component or assembly can go straight from design and style to manufacturing without having the require of creating a drafted paper drawing of the manufactured element. In a sense, the CNC machines represent a special segment of industrial robot systems, as they are programmable to carry out a lot of kinds of machining operations (within their designed physical limits, like other robotic systems).
