    Presented at ICALEO 2006

    Turbine Engine manufacturers are developing solutions for their Laser drilling and cutting Systems which will dramatically speed-up the process of going from part-based geometry data to final machine-based part programs, hence increasing productivity substantially by more efficient utilisation of expensive capital investment in multi-axis Laser machine Tool Systems. The increasing complexity of Turbine part design, including the use of comp...

    Laser cutting is a widespread industrial process. The boundaries for the performance of the lasers in terms of cutting capabilities is steadily moving towards higher cutting rates and thicker section cutting. In this paper the potential of different high power laser sources in cutting is evaluated based upon the historical development, the available cutting mechanisms understanding and the critical parameters involved in high power laser cutting. ...

    Presented at ICALEO 2006

    Despite substantial experimental effort, the meltflow in kerfs is still poorly understood. The ability to expel the melt effectively is severely limiting process performance and cost, especially in narrow thick sections cutting. Various hypotheses exist in the current literature but conclusive proof is still elusive. In order to further the understanding, coupled gasdynamics/meltflow interaction simulation...

    Presented at ICALEO 2006

    Presented is a new approach to CO2 laser processing, and in particular to 3D laser cutting. Sophisticated 5 axis machines with high accuracy are compared to much simpler robot solutions using a 2 kW laser mounted directly to the arm of the robot with an integrated, fixed length, beam delivery system. Although robots with integrated lasers have been around for many years the power levels were restricted so far to 600 W and therefore applicat...

    Laser cutting has been widely applied to profiling materials with uniform thickness. The aim of this study is to explore the problems and effects of cutting non-uniform metallic sheets. Mild steel sheets between 2-3 mm thickness with steps of 0.25 mm were cut using, using both CO2 and Nd:YAG lasers with equivalent cutting parameters and in 4 different cutting arra...
