   Abstract : The Swedish truck industry is forced to find new material solutions to achieve lighter engines with increased strength. Customers and new environmental regulations demand both higher specific power and more environmentally friendly trucks, and this places a rising pressure on the manufactures. READ MORE

4. 12. On Monitoring and Control of Machining Processes

   Author : Mikael Bäckström; Anders Kinnander; Thomas Lundholm; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing engineering; Produktionsteknik; Manufacturing Systems Engineering;

   Abstract : The thesis presents several aspects related to the industrial and academic activities associated with monitoring and control of the machining process and machine tools A survey of the industrial situation identified some key factors for a successful implementation of monitoring and control techniques. Applicable, relatively simple, systems for cutting-process monitoring and adaptive control are available on the commercial market today but the degree of industrial utilisation of the technique is low because the systems are experienced as hard to operate and use, and are at the same time considered unreliable.

6. 14. Information management for the factory planning process

   Author : Danfang Chen; Torsten Kjellberg; Pär Mårtensson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Factory design; information management; models; digital factory; layout design; factory design; Manufacturing engineering; Produktionsteknik;

   Abstract : This thesis is based on the present needs for the factory planning support, of which the most important ones are: • A structured reuse of knowledge and support for industries. Because today the industry handbook in factory planning is not satisfying enough to support this complex process. READ MORE

   Abstract : This investigation is devoted to the study of welding and its effect on the workpiece, focusing on the thermo and fluid dynamical phenomena occuring during a autogenous or nonautogenous arc fusion welding process. Its aim is to simulate the behaviour of the weld pool and analyze the consequence of the solid-liquid phase change, thus obtaining a methodology for predicting the appearance of weld defects related to solidification and cooling.
