  1. 1. Methods for improving performance of process planning for CNC machining : an approach based on surveys and analytical models

    University dissertation from Göteborg : Chalmers tekniska högskola

    Author : Staffan Anderberg; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; CNC machining; metal cutting; performance; process capability; environment; energy; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Process planning as an enabler of competiveness is often overlooked, but being one of the principal function in the product realisation flow it holds a key role by combining both product and production requirements into a production concept with respect to the current manufacturing system. As such the capability of process planning to a large extent dictates production cost, lead times, product quality etc. READ MORE

  2. 2. Improving Machining System Performance through designed-in Damping Modelling, Analysis and Design Solutions

    University dissertation from Göteborg : Chalmers tekniska högskola

    Author : Lorenzo Daghini; Cornel Mihai Nicolescu; Miroslav Píška; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining performance; Cutting stability; Passive damping; High Damping Interface; Boring bar; Turret; SRA - Production; SRA - Produktion;

    Abstract : With advances in material technology, allowing, for instance, engines to withstand higher combustion pressure and consequently improving performance, comes challenges to productivity. These materials are, in fact, more difficult to machine with regards to tool wear and especially machine tool stability. READ MORE

  4. 4. Nanoindentation characterization of high chromium white cast iron for assessment of machining performance

    University dissertation from Göteborg : Chalmers tekniska högskola

    Author : Ling Chen; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanoindentation; FEM; Characterization; High chromium cast iron; Machining; Grid nanoindentation;

    Abstract : As modern production moves towards higher efficiency and cost effectiveness, machining difficult-to-cut materials becomes an increasing challenge. Quickly and reliably characterizing the properties of materials could significantly improve the performance of machining processes in terms of their efficiency and production cost. READ MORE

  5. 5. Control Strategies for Machining with Industrial Robots

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Olof Sörnmo; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Robots; Machining; Control;

    Abstract : This thesis presents methods for improving machining with industrial robots using control, with focus on increasing positioning accuracy and controlling feed rate. The strong process forces arising during high-speed machining operations, combined with the limited stiffness of industrial robots, have hampered the usage of industrial robots in high-end machining tasks.
