2. 1. The green engineer as an enabler of life-cycle management in manufacturing: models and practices

   Author : Birger Löfgren; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete-event simulation; life-cycle assessment; operation management; decision making; practice studies; environmental management;

   Abstract : The last 20 years corporate environmental management has developed from pollution control and emission prevention, to include a greater responsibility for indirect environmental issues along the whole product life cycle. This thesis aims at providing a better understanding of how such environmental life-cycle management can be applied on manufacturing processes. READ MORE

4. 2. Life Cycle Impacts of Road Infrastructure : Assessment of energy use and greenhouse gas emissions

   Author : Sofiia Miliutenko; Anna Björklund; Robert Karlsson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cumulative Energy Demand CED ; Global Warming Potential GWP ; Life Cycle Assessment LCA ; road infrastructure; strategic planning;

   Abstract : Road infrastructure is essential in the development of human society, but has both negative and positive impacts. Large amounts of money and natural resources are spent each year on its construction, operation and maintenance. Obviously, there is potentially significantenvironmental impact associated with these activities. READ MORE

5. 3. Machinability Testing of Materials in Metal Cutting with Focus on Compacted Graphite Iron and Cutting Fluids

   Author : Varun Nayyar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UTS.; Boring; Drilling; Cutting Fluid; Turning; Milling; Force; Wear; Force; Torque; Compressed air; CGI; Hardness; Tool Life; Material Properties; Chip Microstructure; Tapping;

   Abstract : Due to the stringent demands for lower emission from trucks require better mechanical properties of the material to be used in the engines. Better efficiency necessitates higher peak pressure in the engines and for traditionally used material, Flake Graphite Iron (FGI), the mechanical properties starts to reach the limit of what the material can withstand.

6. 4. Methods for improving performance of process planning for CNC machining : an approach based on surveys and analytical models

   Author : Staffan Anderberg; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; CNC machining; metal cutting; performance; process capability; environment; energy; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : Process planning as an enabler of competiveness is often overlooked, but being one of the principal function in the product realisation flow it holds a key role by combining both product and production requirements into a production concept with respect to the current manufacturing system. As such the capability of process planning to a large extent dictates production cost, lead times, product quality etc. READ MORE

7. 5. Robotic Friction Stir Welding for Flexible Production

   Author : Jeroen De Backer; Gunnar Bolmsjö; Giorgos Nikoleris; Anders Robertsson; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction Stir Welding; Automation; Robotics; Aluminium; Lightweight design; Industriell arbetsvetenskap; Industrial engineering; Mechatronics; Mekatronik;

   Abstract : Friction Stir Welding (FSW) is a modern welding process that joins materials by frictional heat, generated by a rotating tool. Unlike other welding processes, the material never melts, which is beneficial for the weld properties. READ MORE
