  1. 1. Machining Monitoring and Control : Based on Parametric Modelling

    University dissertation from Stockholm : KTH

    Author : Mats Bejhem; KTH.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Machining Control; tool condition monitoring; in-process dynamic stability monitoring and control; optimisation of cutting conditions; MC; DSP; TCM; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The objective of this work was the development of aMachining Control prototype system for turning, whichintegrates three fundamental aspects of Machining Controltechnology: Monitoring, Control and Optimisation. MachiningControl refers to the detection and automatic handling ofdisturbances in machining processes. READ MORE

  2. 2. Control Strategies for Machining with Industrial Robots

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

    Author : Olof Sörnmo; Lunds universitet.; Lund University.; [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.

  3. 3. Joint Interface Effects on Machining System Vibration

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Qilin Fu; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Joint Interface; Vibration; Damping; Chatter; Machining; Carbon NanoComposite; PECVD; HiPIMS; SRA - Production; SRA - Produktion; Järnvägsgruppen - Ljud och vibrationer; Järnvägsgruppen - Ljud och vibrationer;

    Abstract : Vibration problems are still the major constraint in modern machining processes that seek higher material removal rate, shorter process time, longer tool life and better product quality. Depending on the process, the weaker structure element can be the tool/tool holder, workpiece/fixture or both. READ MORE

  4. 4. Advances in High Porductivity - High Quality Machining

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Marcel Escursell; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexibility; Quality; Machining; Productivity;

    Abstract : Quality, productivity and flexibility are vital factors in todays machining industry in order to remain competitive. Nowadays, finished products not only have to be produced within specific tolerance limits, but they also have to posses high standards in terms of surface integrity, i.e. READ MORE

  5. 5. Machining of wood : cutting data and its effect on the work environment and surface quality

    University dissertation from Linköping : Linköpings universitet

    Author : Jan Palmqvist; Linköpings universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Machining using circular tools is very frequent in the wood manufacturing industry. Such machinery is very efficient but also leads to problems, for example in the indoor factory environment, in the form of unhealthy wood dust emissions. Another example is imperfections in wood products such as unacceptable surface quality. READ MORE
