Chip control is essential for the manufacturing with geometrical defined cutting edge to avoid interruptions of the process, damages on the machine or injuries of the machine operator. Hereby the prediction of the chip shape is highly relevant and scope of the present research work. High speed filming of the flowing chips, analyses of the contact zones between cutting tool and chip; as well as cutting...
Within this paper a methodology for the assessment of energy and resource consumption within manufacturing processes is described and two case studies from the automotive sector were evaluated. On basis of the Life Cycle Assessment approach the energy and material flows within single manufacturing processes were acquired concerning the two selected case studies. With the generated knowledge about...
The complex design of moulds and dies based upon complicated features and usage of harder materials is a continuous challenge for the development of manufacturing technology for these parts. In this paper we present an algorithm for handling this challenge as well as its implementation by using numerical techniques for the calculation of CNC tool-path. The algorithm consists of multiple stages and...
Rising prices on the international commodity markets as well as the increasing demand on environmental friendly products are generating new needs on product development and process planning. This includes also the development of an energetic product-life-cycle, which does not only comprise the use of a product, but also considers the production and refinement of raw materials at its beginning and...
The growing consequences of global warming and rising prices for fossil fuels are calling for a broad substitution of combustion engines by electrical machines and an energy- and resource-efficient design of manufacturing systems. The present work proposes a conceptual approach for the holistic product lifecycle assessment (LCA) of an electric drive for the automotive industry. The proceeding is part...
Fine blanking can today be used for the production of spur gears but not for helical gears. Based on a newly developed process principle for the fine blanking of helical gears, an analogy process was set up and investigated in finite element simulations using the software Deform-3D. For the numerical model, the tool components were assumed rigid, while workpiece behavior was modeled as plastic with...
