  2. 1. Visualizing the Effects of Geometrical Variation on Perceived Quality in Early Phases

    Author : Ola S Wagersten; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometrical variation; geometry assurance; non-rigid; product development; tolerance analysis; variation simulation; visualization and evaluation.; perceived quality;

    Abstract : In a perfect world, geometrical variation in a manufacturing process would not exist. Every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. READ MORE

  4. 2. Variation Control in Virtual Product Realization - A Statistical Approach

    Author : Kristina Wärmefjord; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; quality control; contact modeling; Variation simulation; welding simulation; spot welding sequence; inspection point reduction; fixture repeatability;

    Abstract : All manufacturing processes are afflicted by variation, which leads to products that may not fulfill assembly, functional or esthetical requirements. The variation in the final product originates from variation in individual parts and assembly processes. READ MORE

  5. 3. 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
