Karl-Hermann Richter, MTU Aero Engines; Munich Germany
Presented at PICALO 2008

Laser machining processes are widely used in the manufacture and repair of aero engine components. This presentation provides examples of well-established, cut-ting-edge and emerging laser machining processes. A well-established process is laser drilling which has been in use for more than 25 years to produce cooling holes in combustors and particularly in high-pressure turbine (HPT) blades and vanes. To enhance the cooling efficiency a novel laser machining technique has been devel-oped to produce sh...

Current Challenges to Laser Cutting Application (Invited Paper)
Authors:
Takeji Arai, Chuo University ; Tokyo Japan
Presented at PICALO 2008

The laser cutting application is used widely in the world industrial field. Especially in Japan, the ratios that the application of the laser cutting occupies exceed 90% in the whole. Currently, the laser cutting technology for sheet metal cutting was developed instead of punching. Although it becomes the main technology, this technology is still in a stage of the middle of development and the technology is still improved rapidly.
For the new challenges are always necessary for mature technology. In industry, nowadays, more high-speed cutting and accurat...

The use of lasers as cutting tools is well established in industry for processing of steels thanks to their great general advantages compared to traditional methods. However, there are materials difficult to be cut by standard laser cutting heads such as some aluminum alloys and ceramics. In this work...

Presented at PICALO 2008

The application of lasers in the microelectronics sector has grown steadily over the past 10 years as DPSS lasers have increased power output and high levels of reliability. The readiness of such systems to operate at various output wavelengths such as 355nm has further enabled a greater range of processing operations for Si based microsystems. Recent advances in Yb doped fiber lasers with ...
