￼INDUSTRY 4.0 Figure 7. Ibarmia Add+processS: Hybrid LMD and machining process system (Ibarmia). From an industrial point of view, there are several machine tool that incorporate both AM and machining processes and give the opportu- nity to the user of combining both processes. The rst hybrid system was presented by DMG MORI in the Eoromold of 2011. Other hybrid machine-tool manufacturers that are already offering this type of solu- tions are Hermle, Mazak, Ibarmia or WFL. In the case of the company Ibarmia, the hybrid machine solution has been developed as a result of its collaboration with the Tecnalia research centre and the University of the Basque Country (UPV/EHU). This machine was presented at the EMO in Milan in 2015 and includes a Ro n bre laser of 3 kW with a coaxial nozzle for LMD operations. The LMD system can be retracted and stored beside the tool changer and machining operations can be activated without any risk for the laser optics. In this way, both mul- tiaxis milling and turning operations can be carried out in the machine. On the other hand, this type of machines needs speci c software solu- tions to program and simulate both LMD and machining operations. In this way, since additive manufacturing and machining operations can be very complex, hybrid machine users need a full support in process parameter selection, simulation and programming. Nowadays there are few software developers offering limited solutions for this technology. However, some companies, such as Siemens is developing AM modu- les in combination with conventional CAM for machining. The use of the same CAM, in the same environment, is critical to program hybrid machines and combine additive and machining operations easily. In this way, one of the objectives of the Paraddise project is to develop a combined CAD/CAM/CAE solution for hybrid machine tools. The Paraddise project is coordinated by Tecnalia and it counts on the participation of Siemens AG, Precitec GmbH & Co. KG, GKN Aerospace Norway AS, Michelin and the University of the Basque Country (UPV/ EHU), RWTH Aachen University. Online monitoring tool for diagnosis of machining processes The integration of tailored devices inside the machine itself is a key issue to reduce failures as much as possible (quality management at design, manufacturing, service and procure- ment stage), to detect failures before parts broken (preventive maintenance with sensing technologies) or to repair as soon as possible after failure (remote monitoring and maintenance system, strong service network, parts supply system). So, a sensing system structure is crucial to track/monitor some of the following items: 1) Power consumption monitor; 2) Machine protection control (bearings); 3) Chatter vibration detection and reduction; 4) Coolant liquid; 5) Servo auto tuning; 6) Hydraulic unit; 7) ATC/ Magazine... Under this perspective, the UPV/EHU High Performance Manufacturing Group propose a monitoring solution built from recon gurable Input/Output (I/O) architecture, recon gurable Field Programmable Gate Arrays (FPGA) and modular I/O. Using RIO hardware and LabVIEW by NI, a Project was specially designed for machining data acquisition and storage. In this case, the authors used a compactRIO which is a modu- lar, recon gurable control and acquisition system designed for embedded applications. This was the preferred option because it has built-in signal conditioning. C-series modules are designed as autonomous measurement systems. All the con- versions A/D and D/A are performed inside the module before data reaches the chassis. Table 1 shows the architecture of the project: 1) Kistler's Type 5171A charge ampli er module to record the cutting forces; 2) NI 9234, using a triaxial accelero- meter and a microphone; 3) NI 9239 and 4) NI 9244, for power consumption. For data storage, we used the binary TDMS le format from NI. This is an easily exchangeable, inherently structured, high- speed-streaming-capable le format without the need for complicated and expensive database design, architecture, or maintenance. The TDMS le format is structured using three levels of hierarchy, le, group, and channel, and the user choo- ses how to organize the data to make it easier to understand. The TDMS le format is a National Instruments platform-sup- ported le format. All NI software development environments interface with TDMS les as part of their native function palet- tes or libraries. There are multiple interfaces to NI TDMS les from NI LabVIEW software. By using this storage system, heavy archives from large recording times (several Gigabytes) can easily be handled and post-processed with Diadem. 56<< Figure 8. Project in LabView; b.
