2. 6. Evaluating the Effects of Variation on Product Appearance through Visual Robustness

   Author : Karin Nordvall; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; product experience; visual quality appearance; visual sensitivity; optical quality; industrial design; perceived quality; craftsmanship; robust design; non-nominal visualization; geometrical variation; visual robustness;

   Abstract : For consumer products where the product appearance plays an important role in meeting expectations, the visible effects of manufacturing variation can have a negative influence on the product experience. A concomitant of mass production is that no manufactured units are exactly identical, as a result of variation. READ MORE

4. 7. Managing Geometrical Variation in Complex Assemblies through Visualization and Tolerance Allocation

   Author : Johan Lööf; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tolerance analysis; and motion envelope.; variation simulation; tolerance allocation; visualization;

   Abstract : To stay competitive in the market today, manufacturing companies have to shorten their time to market. This implies that time also has to be saved during the product development phase. This thesis will mainly focus on how to be more efficient in the detail design phase through different design activities. READ MORE

5. 8. JOINING SEQUENCE ANALYSIS AND OPTIMIZATION FOR IMPROVED GEOMETRICAL QUALITY

   Author : Roham Sadeghi Tabar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Efficiency; Optimization; Sequencing; Geometrical Quality; Non-Rigid Variation Simulation; Joining;

   Abstract : Disturbances in the manufacturing and assembly processes cause geometrical variation from the ideal geometry. This variation eventually results in functional and aesthetic problems in the final product. Being able to control the disturbances is the desire of the manufacturing industry. READ MORE

6. 9. Managing Effects of Manufacturing Variation in Dental Medical Device Treatments - Increasing Geometrical Robustness

   Author : Timo Kero; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mass customization and dentistry.; medical devices; virtual verification; Robust design; variation simulation; tolerance analysis;

   Abstract : Today, there are many solutions for dental rehabilitation. A damaged tooth can be replaced with a dental crown, and a toothless patient can be rehabilitated with implants and a corresponding bridge set-up. Traditionally, a dental crown is manufactured by veneering porcelain to a metal surface that is obtained through the use of casting principles. READ MORE

7. 10. IMPROVING GEOMETRICAL QUALITY BY INDIVIDUALIZING THE ASSEMBLY PROCESS

   Author : Abolfazl Rezaei Aderiani; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometry Assurance; Locator Adjustments; Selective Assembly; Variation Simulations; Individual assembly processes;

   Abstract : Dimensional deviations are a consequence of the mass production of parts. These deviations can be controlled by tightening production tolerances. However, this solution is not always desired because it increases production costs. READ MORE
