A laser‐based technique for finishing of non‐circular cylindrical parts is presented. In this process, the frequency characteristics of a desired non‐circular shape is extracted from a CAD through a Fast Fourier Transform algorithm and implemented through a CO2 laser machining system. A galvanometer‐based scanner is used in the process to achieve programmable beam trajectories and high‐speed finishing. An error estimation scheme can be developed to determine the final dimensional erro...

In Japan, R&D activities on laser materials processing are mainly conducted in universities, public research institutions, and technical centers in private enterprise. Among them the Welding Research Institute and the Department of Welding and Production Engineering, both at Osaka University, have taken the initiative in conducting fundamental studies on laser materials processing as well as training experts and engineers in laser technology since the mid 1960s. In 1990, a new laser center called the Applied Laser Engineering Center (ALEC) was established in Naga...

As the key technology of the Information Superhighway, fiber optics is poised for explosive growth in the next decade. This paper identifies some of the major obstacles involved in establishing a university‐level fiber optics laboratory, and suggests time‐and money‐saving solutions with an emphasis on pre‐packaged fiber optic laboratory kits.

The range and degree of electrical hazards associated with lasers is generally greater than encountered with other forms of equipment in the industrial, commercial, or scientific sectors. In laser equipment the electrical energy conversion to ‘optical’ wavelength energy is achieved by many methods, each method having differing electrical safety hazard exposures. Laser output is described in terms of beam power, energy, wavelength, and spatial characteristics, enabling common points of comparison and beam hazard characterization. In contrast, the methods of electrical energy conversion ha...
JLA Vol:7 Iss:1 (Ultrasonic vibration aided laser welding of Al alloys: improvement of laser welding‐quality)
J. S. Kim
Using a pulsed YAG laser, meltability of Al‐Mg and Al‐Mg‐Si alloys were investigated by a single‐pass irradiation. In order to improve the quality in laser welding, the effectiveness of the Ultrasonic Vibration Laser Welding (UVLW) method proposed in this paper was investigated experimentally. The proposed method was also compared with the traditional welding methods of Normal Laser Welding (NLW) and preHeating Laser Welding (HLW). The welding methods were evaluated from the geometry in the melt zone generated by a single pulse of the laser beam. It was suggested that ultrasonic vibration ...
