1. CNC, Machine Tools and data Exchange in 2013 Presentation at the Turin Industrial Union 2013/05/08 English translation Draft 08/05/2013 Luciano Lauro -Industrial Automation Expert 1

2. Data exchange between CNC machines and the Company Information System 08/05/2013 Luciano Lauro -Industrial Automation Expert 2 Many of the CNC suppliers, like Siemens in the figure on the right, are showing the CNC as interface between Machine Tool and the Company Information System. But there is not yet a de-facto standard, accepted by everybody about this Interface.

3. Present structure used for part program 08/05/2013Luciano Lauro -Industrial Automation Expert3 The traditional CNC programming has a unidirectional information flow: from the Companys Information Systems to the machine. There are no universal standards for complex funcions and each CNC supplier has his own solutions.

4. The information system is able today only to receive data from the PLC section of the CNC 08/05/2013 Luciano Lauro -Industrial Automation Expert 4 This connection will be possible only by the use of STEP-NC. The data, that the traditional CNC machine Is able to exchange with the company Information system is generated by the sequence of functions, that the part program supply to the PLC section of the CNC. The PLC section is designed under the machine tool builder responsability. The PLC section can use the universally accepted standards, OLE – OPC (Open Linking and Embedding for Process control) and the SCADA System (Supervisory Control and Data Acquisition), that are widely used for automation distributed sytems control. Note. STEP Standard for the Exchange of Product data PLM Product Lifecycle Management PLCS Product Life Cycle Support OASIS Open Advanced Standard for the Information Society

5. General Observations The market universal acceptance of a new standard requires a long time. The introduction of new controls will take place only when the current machines will be amortized. The situation of slide 4 will not change immediately in the following years. The concepts of STEP-NC, PLM and PLCS have to be seen as a possible evolution in the following years (10 years? The new investments have to take in account this evolution. We don’t have yet the market response to the new standards. 08/05/2013 Luciano Lauro -Industrial Automation Expert 5
