R&D Projects

Program EUREKA is an initiative of a European network for financing of technological market-oriented projects. It is the leading provider for innovation and support platform for international cooperation of small and medium-sized companies in research, development and innovation of industry and research centres and universities from all technology sectors.

SmartMForming project partnersIn 2016, the CADCAM Design Centar with Slovenian companies Gorenje Orodjarna ltd and TPV trženje in proizvodnja vozil ltd signed partnership on the EUREKA project Smart tools worth 1.1 million Euros with a total length of 3 years.
Sheet metal forming is one of the most important processes in modern industrial production. Nowadays, a large number of parts in the automotive industry, the aerospace industry and the industry of household appliances are made of sheet metal. Processes of forming of sheet metal are quite complicated and require very detailed planning. Over the past few years it has become an even bigger problem due to increasingly complex designed products, high demands on product quality and development of new, very strong and high-quality materials. Today, in the automotive industry for more than 35% of the steel plates are made of high-strength steel, and this percentage is constantly increasing.
The main advantage of using high strength materials is, ultimately high strength of the final product which means that it is possible to make the product less density and less weight in the end. Today there are various methods of improving the formation of the sheet, but many of them are very expensive and only large companies are able to invest in such technologies.

SmartMForming is an innovative development project in which the mechanical power presses with high flexibility replaced with presses with sensors that regulate the status of tools, formation time, stroke and combine two or more operations in one and in that way, shorten production time.

The idea behind project Smart tools is to allow all users the possibility of improvements in technology and the simplification of the whole process of forming the sheet metal using just a few clicks. The idea of smart tools is the existence of the sensors, and the possibility of management tools on-line, such as installation parameters, controlling the state of tools and process optimization.

Eureka certifikate
eureka-logo.pngBefore a new product goes into serial production it must undergo a series of standard tests in order to ensure no failure or malfunction will occur during the service-life. One of the tests is vibration testing, where the product is mounted on the electro-dynamical shaker and excited with the vibration profile that is reasonably more severe than the actual vibration load during the operation. Consequently, in modern engineering this brings up the need for a software tool that predicts the product's life under a given vibration loading in the design stage, before the first prototype is built. The CimFat plug-in for CATIA performs the product life estimation in the CATIA analysis environment with the state-of-the-art methods in the area of vibration fatigue.

Predicting the product's life under a vibration load is a complex challenge, since a number of different vibration loads and types of loading are used for the product testing. The CimFat plug-in for CATIA offers a simple and clear way to perform vibration fatigue analysis in form of the additional analysis case.

The benefits of the CimFat plug-in are:

  • the time-to-failure prediction of a product for a given vibration load
  • comparison of different designs with respect to the fatigue criteria
  • avoid design changes in the prototyping or production stage due to the unexpected fatigue damage during the shaker-testing
  • vibration fatigue calculation, integrated in the standard numerical analysis of the product

eureka-logo.pngIn the development of automotive components operating under cyclic loading conditions a prediction of lifetime is an important issue. Since many of those components are exposed to high-cyclic fatigue it is obvious that the infinite lifetime concept should be used in the design of such components. This means that components are designed to keep the stress state during imposed cyclic loading below the endurance limit curve, so called S-N or Wöhler's curve . If the component is loaded below this limit then no initiation of fatigue cracking with possible subsequent fatigue failures is expected, regardless of the number of loading cycles.

Several fatigue criteria were developed for the fatigue endurance estimation of dynamically loaded components, however, the most commonly used one in the automotive industry is the Dang Van fatigue criterion, which is used in FatigueDV Plug-in for CATIA. The advantage of this criterion is in its ability to estimate infinite lifetime endurance for components subjected to arbitrary cyclic loading, here included also time dependent multi-axial stress states.

FatigueDV Plug-in for CATIA enables an engineer:

  • to estimate fatigue endurance of a dynamically loaded numerical model (model in the frame of the finite elements modeling) with respect to the Dang Van fatigue analysis
  • to gain required fatigue material data for new materials by performing material experiments using standard material testing equipment
  • to asses the quality of the results thus obtained and, consequently
  • to make the necessary changes to the model (product/part undergoing fatigue damage) in order to enhance the product/part using parametric and/or modification analyses using either custom or commercial finite element software or even using specialized optimization approaches by extending/using the program with other state-of-the-art software tools

CNC&IT Leonardo da Vinci partnership project includes four secondary vocational schools from Slovenia, Poland, Turkey and Croatia, as well as partners from the World of work which are Slovenian company CADCAM Lab , Spanish company Talleres Tibi and a non-profit research center AIJU also from Spain.

The goal of the Project is to raise the professional competence of teachers and students skills of partners secondary vocational schools, and improving curricula in the areas involved in the Project.

The project is implemented through the development of new product produced by CNC technology, monitoring it via web site and designing multimedia teaching materials. The new manufactured products are representative souvenirs of regions of partner schools.
