In this paper, we discuss an Internet based excimerlaser-micro-machining services model that allows multiple users to collaboratively design and fabricate laser micromachining features. This model implements the client server architecture to support design and editing of features by multiple clients. The client side needs minimum software installation and is made intelligent by incorporating fe...

An experiment was conducted to compare the effects of ultrasonic and non-ultrasonic on glass lens using rotary ultrasonic machining (RUM) technology. The primary objective of this study is to analyze the experimental results of the grinding operations using Taguchi method. Feed rate and frequency are the main process parameters to be tested in this experiment. A three-level orthogonal array tab...

Advanced engineering ceramics which are widely used as high strength refractory material for several industrial applications, always pose a challenging opportunity to machine them. Conventional methods of machining are difficult to shape them because of their high hardness and brittleness, while grinding is the only popular method to machine them, but shaping of ceramics in desired form is diff...

Micro-optical devices, e.g., micro lenses, micro mirrors, play an important role in high speed data, voice and video signal transmissions. In this study, a new method of fabricating micro optical devices was investigated. The method is different from traditional fabrication processes in the sense that that the micro optical elements were simultaneously machined in a process known as slow tool s...

The size of every component for opto-electrical devices or micro electro-mechanical systems (MEMS) has been reduced in recent years due to progress in opto-digital communications technology. The demands for micro-sized holes, slits and 3D structures of hard brittle materials such as ceramics and glass are considerable, and this has stimulated research into new methods and systems for a micro-me...

Ultrasonic Vibration-Assisted Machining (UVAM) has been investigated as one of the most suitable methods to imprint patterns on metal surfaces. Actually, UVAM, a consequence superimposition high-frequency and small-amplitude vibration cutting tool motion, makes possible generation micro-textured On basis pattern parameters, process characteristics, micro-dimples different morphology dimension c...

In recent days, the micro/nano machining becomes an important process to fabricate micro/nano scale dimensional patterns or devices for many applications, especially in electrical and electronic devices. There are two kinds micro-machining in use. i) bulk micromachining, ii) surface micro-maching. In the case of bulk micromaching, the structures can be made by etching inside a substrate selecti...

In the past many qualified technologies have been established for the manufacture of optical, precision and micro parts as well as precision structured surfaces. In this field mechanical machining processes, like diamond machining, play a dominant role. Novel mechanical manufacturing processes, further development of ultra precision machine tools and the precision machining of challenging mater...
