Project of Control of the Open Cnc in Agile Manufacturing System

Abstract. Competition in the market is getting more and more globalized and the fast technological changes force manufacturers to search for new ways to stimulate the productive system to the market requirements. Several proposals have been put forward in an attempt to solve the problem of the control of productive systems distributed whenever it is necessary to include a new process in the system. To reach this goal, it is necessary to develop a new model which includes agile manufacturing. The purpose of this article is to project the control of agile productive systems with Computerized Numerical Control (CNC) of Open Architecture. The organization, people and the combination of machines with traditional CNC, dedicated workstations, CNC of Open Architecture, form the Productive System. The introduction of the philosophy of Open Architecture in the control of the operation of machines has given rise to a new phase of controllers. The new CNC generation of Open Architecture keeps the CNC technology (control of position and rotation) and adds to it the technology of computers (programming has become easier, configuration, net communication), and it has structures that enable changes in the hardware configuration and changes in the software for all the levels of control. Through the Open CNC Architecture we have increased the flexibility of the machine-tool and it also makes it possible to develop a new way to treat the control at the management level of production in the plant. In this essay the control has been developed by the integration of superior levels through the Norm ANSI ISA S95 and implemented through the Norm IEC 61499.
