Cutting Mechanisms

Multi-material structures made from renewable materials are increasingly being addressed in research and industry. Especially lightweight applications based on wood and polymer materials offer an important opportunity to reduce weight and CO2 emissions, and thus create a sustainable economy. When establishing new material combinations, it is necessary to take economical and efficient manufacturing processes into count to enable the market entry. Therefore, the existing manufacturing processes needed to be adapted and improved in terms of the specific machining characteristic of the wood material. This study targets a combined process where a forming and shear-cutting process is also integrated in an injection-molding tool. The findings on the shear-cutting process of wood veneers are not widely investigated yet. Therefore, process and material-related dependences like cutting velocity, tool shape design, and preconditioning of wood veneers were examined. The target values cutting force and cutting-edge quality were used to describe the relations. The results showed specific damage and fiber fractions of the wood material compared to the isotropic materials (e.g., metal). In addition, low cutting forces appeared by realizing a drawing cut and high cutting speeds. A decrease in the cutting force with a higher moisture content could not be shown for the used wood types.

Game Industry

In the context of the serious games industry, up to now the most commonly used BM among developers representing SMEs consists in offering an individual product to the customer, based on tailored one-of a kind production. Such production has high costs and low re-usability and leads to a long time-to-market. For an industry dealing with products highly dependent on technological advances, this implies high risks for failure and thus being put out of business. Consequently, an increasing number of Serious Games developers are struggling to survive. These trends are not specific for the SG development sector, but can actually be observed in several others, like software industry as well as the manufacturing industry, where a transition to less product-oriented BM can be observed. This article is based on an analysis of cases studies to outline how such a transition might be possible also within serious game industry, but also to discuss the threats and opportunities of the transition, both based on case studies as well as on comparison with experiences in other industries

End-user development is a growing domain; however, few dedicated end-user development tools exist allowing end-users to incorporate their domain knowledge into software solutions. EUREQA is a design pattern driven UML class diagram modeling tool allowing end-user developers to create UML class diagram models reflecting their domain knowledge. The UML class diagram can be used as a basis for model-driven development. EUREQA was evaluated with 20 participants recording data through direct observation, screen recordings, the think-aloud protocol and semi-structured interviews. Half of the participants used EUREQA and the other half used the Microsoft Visio modeling tool. The authors found that EUREQA participants scored higher than Visio participants for this task and that skill had less effect on the EUREQA participants’ solutions. Specifically inexperienced EUREQA users struggled less when working with UML class diagram elements compared to Visio participants.

Tele Monitoring

This study deals with the construction of network system for the production site, for the purpose of networking the machine tools as a part of the whole system. The Tele-monitoring for transformation of monitored information was studied. From the point of view of monitoring, the recognition of abnormal is very important in reducing the burden of an operator or for long-time unmanned operations. We then propose a method for the detection of abnormal in cutting process by analyzing the cutting sounds using Fourier transform, filtering, correlation analysis and statistic treatment. For the checking of tool wearing progressing, an experiment was arranged for the recognition of the sounds from a worn tip in comparison with a new one. On the detection of tipping of the cutter, a new tip is used for a long-time cutting without tool exchanging. The change of worn width and related values were compared with the original standard. It was found that the detection of tipping is possible by continuously sampling the cutting sounds and monitoring their correlation.

The Heat Balance

The aim of the work is to define a methodology and to develop specific tools that allow engineers to investigate and fully characterize the thermal performance of an aero-engine turbine module. The thermal behaviours of a complex system are the result of strong interactions between the fluid-dynamics aspects, the heat balance within each component and the geometric variations mainly due to the thermal and mechanical loads. All these phenomena are strictly connected and cannot be studied separately without introducing approximations and /or errors in the final results. For long time the industrial approach in turbine design has been based on separate analyses of the phenomena with manual iterations between them to allowed acceptable solutions to be reached. The new requirements in reducing the product time-to-market together with the need of higher accuracy in the design, have driven the development of new approaches based on the multi-disciplinary analysis integration. This paper will summarise the AVIO approach to the turbine design procedure upgrade, mainly focused on the thermal analysis and clearances control. A detail of the methodology used will be presented together with a description of the tools developed. A comparison between numerical predictions and experimental data (full engine test) will be reported.
