2. 1. CAD Integrated Quality Control

   Author : Martin Helgoson; John Corbett; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The thesis concludes the research work aimed at quality monitoring of parts associated with double twisted surfaces. Different CAD/CAM-based approaches and parameters for quality evaluation have been proposed. READ MORE

4. 2. Variable Valve Actuation in a Spark Ignition Engine - A Flow Field and Heat Release Study

   Author : Fredrik Söderberg; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; framdrivningssystem; Gases; plasma; fluid dynamics; plasmas; Gaser; fluiddynamik; vakuumteknik; vibrationer; akustik; Motors and propulsion systems; Motorer; hydraulik; Maskinteknik; vibration and acoustic engineering; Laser Doppler Velocimetry Particle Image Velocimetry PIV LDV Wavelet Computational Fluid Dynamics CFD Variable Valve Actuation Timing Turbulence Combustion Engine Spark Ignition Miller; hydraulics; vacuum technology; Mechanical engineering;

   Abstract : The objective of this thesis was to find ways of improving part-load efficiency for a spark ignition engine by studying the effects of variable-valve actuation on fluid flow and combustion. The in-cylinder flow was measured with laser doppler velocimetry, LDV, and particle image velocimetry, PIV. READ MORE

5. 3. Zirconia as a biomaterial for odontological applications : effects of composition and manufacturing processes on fracture resistance

   Author : Anders Sundh; Göran Sjögren; Krister Nilner; Umeå universitet; []
   Keywords : CAD CAM; ceramics; HIPing; Mg-PSZ; veneering; Y-TZP; zirconia;

   Abstract : Background: Ceramics have long been amongst the most biocompatible materials known but their mechanical properties have limited their use. During the past few decades zirconia has aroused particular interest as a biomaterial because of its greater flexural strength, fracture resistance and toughness compared to other bioceramics.

6. 4. Integration and communication of engineering information in collaborative design

   Author : Haoxue Ma; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

   Abstract : In recent years, the rapid development of computer technologies has greatly impacted the product development process. In the engineering area, powerful computer-based tools such as Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) systems enable engineers to fulfil various design tasks and realise product concepts in the early phase of the product development process, without physical parts actually being manufactured.

7. 5. Principles for modelling of manufacturing sequences

   Author : Mats Werke; Mihai Nicolescu; Carin Andersson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production Engineering; Industriell produktion;

   Abstract : The manufacturing sequence influence, to a large extent, component properties like fatigue life, shape accuracy and manufacturability. By simulating the manufacturing sequence, using numerical or empirical models, and extracting important accumulated data, like residual stress, hardness and shape, the possibilities of early analysis of a design concept and the associated manufacturing sequence will increase.
