CNC controls are also referred to as soft- wired NC systems because most of their control functions are implemented by the control software programs. These machines are used independently of one another or in succession to manufacture or assemble parts into a final product. b) feedback system. CNC Control Systems : 4. It is typically set up with 3 directions of movement referred to as the X, Y and Z axis. On every CNC machine, there is an electronic measuring system on each controlled axis. Today, computer numerical control (CNC) machines are found almost everywhere, from small job shops in rural communities to Fortune 500 companies in large urban areas. In a CNC Machine functions and slide movements are controlled by motors using computer programs. CNC machines rely on a system of three linear and three rotational axes in order to calculate the motion and position of machine components and workpieces. Introduction to CNC Machining 22. mill, lathe, drill press, etc.) Nowadays the manually controlled machine exists like a CNC machine and even do with the help of feed mechanism the lathe machine operates manually. The structure of the CNC machine is therefore designed to cope with the torsional forces and heavy duty cutting imposed on these machines. Control units for NC machines are usually hardwired, which means that all machine functions are con- trolled by the physical electronic elements that are built into the controller.
