  1. 1. Variation Control in Virtual Product Realization - A Statistical Approach

    Författare :Kristina Wärmefjord; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Intention recognition in human machine collaborative systems

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robot motion planning; geometrical quality; equipment utilization; robust design; Sheet metal assembly; tolerance analysis;

    Sammanfattning : Automobiles are an integral part of modern society and its way of life. In addition, automotive manufacturers are important institutions in society, summing the work of a vast array of sub suppliers, employing many. The margins are however moderate and competition is fierce. LÄS MER

  5. 4. A Computational Framework for Control of Machining System Capability : From Formulation to Implementation

    Författare :Andreas Archenti; Cornel Mihai Nicolescu; Mamoru Mitsuishi; KTH; []

    Sammanfattning : Comprehensive knowledge and information about the static and dynamic behaviour of machine tools, cutting processes and their interaction is essential for machining system design, simulation, control and robust operation in safe conditions. The very complex system of a machine tool, fixture and cutting tools during the machining of a part is almost impossible to model analytically with sufficient accuracy. LÄS MER
