    Presented at ICALEO 2012

    Momentum and heat transfer of inert gas jet to the melt in laser cutting is studied well by numerous researchers. Gas dynamic conditions of cutting with oxygen are significantly different from inert cutting: only 0.3 bar of high purity oxygen are enough to cut 10mm plate. Such a pressure level is absolutely insufficient for inert gas cutting. This paper is focused on the influence of...

    Presented at ICALEO 2012

    This paper presents a direct comparison of fiber laser and CO2 laser cutting machines from a "what laser should you buy next?" point of view. Both types of machine have their drawbacks and advantages, and a direct comparison needs to compare costs, cutting speeds, cut quality and several other factors, including maintenance and safety considerations. The overall conclusion of the paper is that, from a jobshop perspective, the CO2 laser is a mor...

    Presented at ICALEO 2012

    Modern techniques of laser material processing require not only simple homogenizing of a beam, but also more freedom in manipulation of intensity profile and generating such profiles like super-Gaussian and inverse-Gaussian; controllable varying of the intensity profile allows to adjust" a particular material processing technology, improve it or make more efficient. These tasks can be successfully accomplished using the field mapping refractive beam shaping optics like piShap...
