The market pressure and the products of competitors are decreasing the duration of product life cycles. Besides that, special customer requirements and rising product complexity result in an increase of the effort and the costs of the development process. In order to minimize the effort of the development process as well as to handle the uncertainties which come along with the planning and selection of manufacturing systems a data-based configuration tool was developed for the use in the field of sheet metal forming. Based on the product data of existing press systems, the tool is able to predict the fundamental configuration of a newly developed press system. The utilization and functionality of the tool is illustrated on two exemplary press systems.

Design And Manufacturing

Sheet metal forming tools play an important role in the manufacturing of many products. With shorter product life cycles and demand for shorter time to market for new products, the process for design and manufacturing of stamping tools becomes a critical part. Stamping dies are often designed and manufactured by smaller, specialized companies. For a tooling company, knowledge and experience is an important competitive advantage. Traditionally the design process has been characterized by being based on few key individuals with much experience and craftsmanship. To stay competitive in this market there is a need for more efficient processes, systems, tools and supports in order to become more industrialized. This paper presents results from a study of the state of practice in industry within progressive stamping tool design as well as a review of relevant literature. The design and manufacturing processes for stamping dies in six companies have been investigated through semi-structured interviews, from which the main challenges in the current state for the companies are identified. The results from the interviews was analyzed and compared to the established concepts and frameworks of methods found in the literature review. The results and analysis points in the direction of efforts needed in supporting the formalization and reuse of information and knowledge from previous tool projects and production, especially during the critical steps of tool process planning and creating the tool layout.

Innerhalb des Projekts „HyBlade“ wurde ein Flügelprofil aus Stahlblech entwickelt. Zum Einsatz kommen bewährte Fertigungstechniken wie das Abkanten einer Vorform und das Hydroforming zum Kalibrieren der finalen Geometrie. Das Verfahren stellt eine hohe Maßhaltigkeit sicher – die wesentliche Voraussetzung für gute Aerodynamik und hohe Energieausbeute von Windkraftanlagen. Die wirtschaftliche Prozesskette gestattet darüber hinaus auch die Herstellung größerer Blätter mit weitaus komplexeren Geometrien.   In the HyBlade project, a sheet metal based airfoil used for blades of small wind turbines has been developed. Well known forming techniques have been used to produce a bent preform that is finally calibrated via hydrofoming. This manufacturing technology ensures a high accuracy of the blade, resulting in good aerodynamic conditions and energy efficiency. The very cost-effective process chain furthermore offers the possibility to form even larger blades with a higher geometrical complexity.

Abstract The article presents a properly planned and designed tests of the abrasive wear resistance 2024 aluminum alloy strips under friction conditions involving various lubricants. Test were focused on the selection of the best lubricant for use in industrial environment, especially for sheet metal forming. Three lubricants of the Orlen Oil Company and one used in the sheet metal forming industry, were selected for tests. Tests without the use of lubricant were performed for a comparison. The tester T-05 was used for testing resistance to wear. As the counter samples were used tool steel - NC6 and steel for hot working - WCL, which are typical materials used for tools for pressing. The results are presented in the form of the force friction, abrasion depth, weight loss and coefficient of friction depending on the lubricant used and the type of counter samples. The results allowed for predicting set lubricant-material for tools which can be applied to sheet metal made of aluminum alloy 2024.

In this study, the lump growth model, described in an accompanying paper (de Rooij and Schipper, 2000) is validated by means of experiments performed on a deepdrawing simulator. In the experiments, the influence of material and roughness properties of both sheet and tool on the galling behavior is determined. For these experiments, a deepdrawing simulator and a selection of aluminum and zinc coated sheets with several (coated) deepdrawing tools are used. Good agreement is found between results of the lump growth model and the sheet metal forming experiments.

Stamping Part

An increasing demand for lower price and better quality vehicle has increase complexity of tool development process. This includes concept evaluation, design phase, prototype phase and pre production phase. Experience show that R&D spends most of the time and cost for tool development process, which includes assembly tooling, product tooling for automobile sheet metal component or part requires the highest cost in tool development process as most metal stamping part requires more than one tool to produce finished stamping part. For these reason, sheet metal forming simulation and analysis at early stage of tool development process is very important to shorten the tool development cycle time and cost. In other word by applying sheet metal forming simulation and analysis at early stage it can reduce the die manufacturing cycle time and cost.

Productivity is one of the major factors that affect the profit of any industry or any product. In manufacturing industries, the productivity is showing the efficiency of the production unit. It depends on many factors such as technology, machine, method, management, materials etc. In this study, material used is considered and analyzed how it affects the productivity. Productivity is normally expressed as the number of units produced / unit time. Sheet metal forming is one of the major manufacturing processes and used for most of the products. So the selection of material is important for good quality as well as economical production. This article discusses how the material influences the productivity. For this study, a product U Clamp is considered. The materials considered for the study are the aluminum and mild steel. The U clamps are formed by aluminum as well as mild steel by using the same die. Data on operation time, material handling time are collected, analyzed and discussed.

Practical Recommendations

To determine the accuracy of the readjustable punches for separating operations (perforation + punching out) of sheet-metal forming, the accuracy parameters were analyzed using the random balance method using the method of experiment planning. Analytical dependencies are obtained to determine the values of deviation of the outer and inner contour dimensions of perforated and punched out sheet parts. From the dependencies obtained, it is possible to estimate and predict the value of deviation in the dimensions of the resulting part at any time during the operation of the punch. Practical recommendations on the calculation of the actuating dimensions of the working elements (stamping punch, matrix) of readjustable punches are offered.
