Development of new open soft-CNC system

Computer Numeric Control (CNC) machine has been widely used in the industries since its development, this technology had made a strong impact in the growth of the manufacturing world. Today in industries this technology has been used for various operations like milling, drilling, packing, welding etc. However, the rapid growth in the manufacturing world increases the demand of more flexibility in the CNC machines. Commercial CNCs were fail to provide flexibility because its structure was found to be of closed nature, which does not provide access to the inner features of CNC. In order to overcome that problem, Open Architecture Control (OAC) technology was introduced, at present Personal Computer (PC) has been the best platform for development of open-CNC system. In this paper, a new method of open-CNC development has been presented that utilized motion control card, universal motion control interface and various functional modules for position, spindle and tool changer motion control. The system was experimentally implemented on old 3 axis CNC milling machine and found to be satisfactory in performance. Overall, the proposed technique had enabled a minute part of sustainable manufacturing environment.
