Answer :

Ans: Working Principle of a CNC Machine

A highly skilled operator enters the information using a Human Machine Interface Device in the form of M or G codes. The memory of the information converts into binary codes that send electric pulses to the Servo drives. In response, these signals actuate the spindle and motors.

Final answer:

CNC lathe machines operate on computer numerical control to execute precise, automated cuts on a rotating workpiece. It evolved from earlier lathes like the Blanchard lathe, now utilizing laser precision, greatly improving operational efficiency and reducing waste. Such lathes significantly contributed to mass production and specialized labor in manufacturing industries.

Explanation:

The CNC lathe machine operates on the principle of computer numerical control (CNC) where a cutting tool is used to remove material from a rotating workpiece to shape it into the desired form. Precise, automated movements guided by a program containing coded alphanumeric data execute the machining operations.

One historical example of lathe advancement is the Blanchard lathe, a pivotal development in the evolution of lathing technology. The modern CNC lathe is a vastly improved version that can use a laser sight for precision cutting, outperforming any manual operation.

Machines like the Blanchard lathe fed into a system of specialized labor, enabling the mass production of uniform parts like those seen in rifles. As the operational efficiency improved, reducing material waste, the overall operating costs of machinery decreased. They also allowed for the American system of manufacturing, where precision parts are produced en masse for assembly into final products like bicycles, sewing machines, and typewriters.
