Transcript of CNC Machines
Computer Numerical Control (CNC) machines are automated milling devices that make industrial components without direct human assistance. They follow coded instructions that are first sent to an internal computer that then runs the machine.
The idea of numerical controls is generally credited to John T. Parsons.
Indian springs manufacturing is a company specializing in CNC machining and manufacturing in Syracuse NY.
In 1958 MIT published its report on the economics of NC. They concluded that the tools were competitive with human operators.
Germans were the first to see the opportunity to reduce the cost of CNC machines, and by 1979 the germans were selling more CNC then the United States.
The first machines were built in the 1940s and 50s, based on existing motors that were modified with motors that followed punched tape.
CNC mills are able to cut raw material with absolute accuracy and are a huge improvement over manual mills.
The use of technology (CNC) to ease human labor is called automation.
