Computer Numerical Control Cutting

A machine tool automation systems operated by programmed commands and stored mediated abstark storage, it is contrary to the previous practice where machine tools are usually controlled by hand or automation simple rotation using the cam. NC's own words in the English language is an abbreviation of the word that means the Numerical Control Numerical Control. The first NC machines were first invented in the 40s and 50s, by modifying ordinary machine tools. In this case the machine tools are added to the motor which will move the controller to follow the points entered into the system by recording paper. Engine blend of servo motors and mechanical system is immediately replaced with analog and then digital computers, creating the modern tooling machines called CNC (computer numerical control) that would later have revolutionized the design process. Currently CNC machine has a very close relationship with CAD programs. CNC machines are built to meet the challenges in the world of modern manufacturing. With CNC machining, precision of a product can be guaranteed up to 1/100 mm, workmanship mass product with the exact same results and fast machining time.
