  2. 1. Adaptive Active Control of Machine-Tool Vibration in a Lathe - Analysis and Experiments

    Author : Lars Håkansson; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Metal Cutting; Lathe; Tool Vibration; Active Control; Adaptive Signal Processing; materialteknik;

    Abstract : In the turning operation the relative dynamic motion between cutting tool and workpiece, or vibration, is a frequent problem, which affects the result of the machining, and in particular, the surface finish. Tool life is also influenced by vibration. READ MORE

  4. 2. Design, Modelling and Control of Electrical Machines - With Applications to Iron-powder Machines and Acoustic Noise

    Author : David Martinez; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BEM; induction machine; noise prediction; vector control; acoustic noise; HEV; series magnetization; leakage reduction; thermal model; FEM; MEC; claw-poles; SMC; slip-ring-less machine; sound intensity measurements; vibration; Electrical engineering; Elektroteknik;

    Abstract : This thesis consists of two parts, the first dealing with the design of iron-powder synchronous machines, and the second with the analysis and prediction of the acoustic noise in electrical machines. In Part I, a 1.6 kW electrically magnetized claw-pole machine with magnetically conducting end-plates has been analyzed and a prototype tested. READ MORE

  5. 3. Joint Interface Effects on Machining System Vibration

    Author : Qilin Fu; Cornel-Mihai Nicolescu; Tomas Beno; KTH; []
    Keywords : 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

  6. 4. Analysis, Modeling and Simulation of Machine Tool Parts Dynamics for Active Control of Tool Vibration

    Author : Tatiana Smirnova; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Boring bar vibration in machine tools during internal turning operations is a pronounced problem in the manufacturing industry. Due to the often slender geometry of the boring bar, vibration may easily be induced by the material deformation process. One approach to overcome such vibration problems is to use active control of boring bar vibration. READ MORE

  7. 5. Dynamic Analysis and Modeling of Machine Tool Parts

    Author : Tatiana Smirnova; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Boring bar vibration during internal turning operations in machine tools is a pronounced problem in the manufacturing industry. Vibration may easily be induced by the workpiece’s material deformation process, due to the bar’s normally slender geometry. READ MORE
