...Vishnu Vardhan Posa; Murali Sundaram Laser beam machining (LBM) is a versatile process that can shape a wide range of engineering materials such as metals, ceramics, polymers, and composite materials. However, machining of glass materials by LBM is a challenge as most of the laser energy...

...Xiaoji Zhang; Chao Wei; Yuan-Hui Chueh; Lin Li In this paper, we present a new approach of combining point-by-point selective powder delivery with powder bed fusion for multiple material (metal/glass) components printing. Dual ultrasonic vibration was used to achieve stable flowrates of both 316 L...

...Panjawat Kongsuwan; Gen Satoh; Y. Lawrence Yao Femtosecond laser pulses were focused on the interface of two glass specimens. Proper use of optical and laser processing parameters enables transmission welding. The morphology of the weld cross section was studied using differential interference...

...A. Brient; M. Brissot; T. Rouxel; J.-C. Sangleboeuf Surface finish determines service life of glass workpieces. Therefore, an extensive polishing phase is usually performed to limit the local irregularities. In this paper, we propose to investigate the influence of the grinding parameters...

... in laser cutting of glass with the controlled fracture technique is the cut deviation at the leading and the trailing edges of the glass sheet. This work is about minimizing this deviation through an optimization process, which includes laser beam geometry. It has been established that the thermal stresses...

...Koji Yamamoto; Noboru Hasaka; Hideki Morita; Etsuji Ohmura A mechanical breaking process after laser scribing is indispensable to complete the separation of glass substrate since the crack depth induced by the laser scribing is limited. Laser irradiation along the laser scribed line is introduced...

... volume fraction, and viscosity of the resin. In the present work, a three-dimensional finite volume technique is employed to simulate the liquid resin flow through the fiber reinforcement in the injection pultrusion process. The numerical model simulates the flow of polyester resin through the glass...

...Masahiko Yoshino; Sivanandam Aravindan This paper reports on nanosurface fabrication of hard brittle materials by structured diamond tool imprinting. Ultrafine structured surfaces were fabricated on soda glass, firelite glass, quartz glass, quartz wafer, and silicon. A specially designed...

...Zhiyong Wei; Kok-Meng Lee; Zhi Zhou; Siu-Ping Hong Optical fibers are drawn from preforms (fused silica glass rods) typically made up of two concentric cylinders (the core rod and the clad tube), which are usually joined in a separate fusion process. The setup time and hence manufacturing cost can...

... scratching test device, and the pin-on-disc scratching tests were conducted with three (3) hard-brittle materials (i.e., silicon, glass, and quartz) under pressure of 400 MPa and zero MPa. Traces of scratches on these specimens were examined with microscopes to evaluate the effects of hydrostatic pressure...
