1. Chemometric and signal processing methods for real time monitoring and modeling : applications in the pulp and paper industry
Sammanfattning : In the production of paper, the quality of the pulp is an important factor both for the productivity and for the final quality. Reliable real-time measurements of pulp quality are therefore needed. LÄS MER
2. Feedback Control of Robotic Friction Stir Welding
Sammanfattning : The Friction Stir Welding (FSW) process has been under constant developmentsince its invention, more than 20 years ago. Whereas most industrial applicationsuse a gantry machine to weld linear joints, there are applications which consistof complex three-dimensional joints, requiring more degrees of freedom fromthe machines.

3. Optimized processes in sawmills
Sammanfattning : This work was initiated in order to show the potential for Swedish sawmills to achieve higher productivity by implementation of improved process control tools in breakdown and production flows. Accessible and reliable production data are crucial information concerning the area of process control; hence the objective in this study was to create a "toolbox" of suitable tools for decision support, surveys and analyses.

4. Skärkrafter vid fräsning : teori och verklighet
Sammanfattning : This thesis deals with the machining method milling and the forces affecting the tool during a milling operation. A survey of different tool geometries and conditions of the tool engagement during a machining process is presented. The general cutting theory and the equations used to estimate the load are explored. LÄS MER
5. Geometrical and dimensional Measurement Planning : - a systematic and holistic approach
Sammanfattning : För att försäkra sig om den slutliga kvaliteten på maskinbearbetade komponenter måste tillverkande företag mäta och verifiera de geometriska och dimensionella egenskaperna på komponenter innan dem skickas vidare nedströms till den mer värdeskapande monteringen. Det är idag vanligt att den geometriska och dimensionella mätningen och verifieringen uppstår varje gång då en maskin ställs om, när man startar om eller startar upp en ny produktionslina eller då en produktionsprocess ändras.
