  5. 3. Experimental and theoretical investigation of the laser cutting process

    Author : Jetro Pocorni; Ali Khan; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling; Maskinteknik;

    Abstract : This thesis concerns experimental investigations of laser cutting with theoretical and practical discussions of the results. The thesis is made up of three papers which are linked in such a way that each of them studies a different aspect of laser cutting: In paper I the two major laser types in cutting, namely CO2 and fiber lasers, are compared to each other by a self-defined cut efficiency.

  6. 4. On the physics and chemical thermodynamics of laser cutting

    Author : Anders Ivarson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Abstract : Over the past two decades C02 laser cutting has grown from an obscure laboratory technique into an important branch of manufacturing engineering. Industrial application of the process has been extremely successful even though the cutting process is not thoroughly understood in detail. READ MORE

  7. 5. Interaction mechanisms for a laser-induced metallic boiling front

    Author : Ramiz Saeed Matti Samarjy; Alexander F.H. Kaplan; Torbjörn Ilar; Michael Schmidt; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser remote fusion cutting; Boiling front; High speed imaging; Additive manufacturing; Ejection; Absorption; Wavy surface; Deposition; Produktionsutveckling; Manufacturing Systems Engineering;

    Abstract : This thesis is about fundamental interaction mechanisms of laser remote fusion cutting, RFC, which is based on the formation of a quasi-stationary laser-induced boiling front that causes drop ejection, preferably downwards. Laser cutting of metals, invented in 1967, has developed from a niche to a well established high quality cutting technique in the manufacturing industry. READ MORE
