Number of pages 314. Micromachining is used to fabricate three-dimensional microstructures and it is the foundation of a technology called Micro-Electro-Mechanical-Systems (MEMS). Bulk micromachining and surface micromachining are two major categories (among others) in this field. This book presents advances in micromachining technology.

The goal of micro-machining is to achieve the required accuracy in one single machining step without being forced to iterate slowly converging machining and testing cycles. Thus, all parameters that affect the accuracy of the process must be identified and controlled as much as is needed for reliably reaching given tolerances.

Laser Microprocessing. Micromachining of fine features has become an integral part of high-volume manufacturing in markets as diverse as consumer electronics, medical devices, and automotive. Tiny holes, fine cuts, and narrow scribes are created with precision drills, saws, routers and, with increasing frequency, lasers.

micro machining machining of micro parts is not literally correct. removal of material in the form of chips or debris having the size in the range of microns. creating micro features or surface characteristics (especially surface finish) in the micro/nano level. definition: material removal at micro/nano level with no constraint on the size …

A brief review is focused on laser micromachining of materials. Micromachining of materials is highly widespread method used in many industries, including semiconductors, electronic, medical, and automotive industries, communication, and aerospace. This method is a promising tool for material processing with micron and submicron resolution. In this paper …

Electrochemical micromachining (EMM) is a potential process to fabricate microcomponents that are stress free and have good surface finish. The process differs from conventional electrochemical machining in view of small interelectrode gap and ultrashort pulses and the larger significance of electric double layer in precise material removal.

Femtosecond laser micromachining has emerged in recent years as a new technique for micro/nano structure fabrication because of its applicability to virtually all kinds of materials in an easy one-step process that is scalable. In the past, much research on femtosecond laser micromachining was carried out to understand the complex ablation …
