Laser Machining

Springer Science & Business Media. 2013

Laser Machining: Theory and Practice addresses state-of-the-art laser machining in a way useful for research- ers, academicians and practitioners, particularly manufacturing engineers, who are considering lasers as a solution to the machining requirements of their factories and plants. This book provides detailed information on the theory behind laser machining, as well as its requirements, uses and applications. In order to place laser machining in its correct context, the author begins with an overview of conventional material removal processes and go on to describe in detail the physical mechanisms involved in lasers, the different types of lasers involved in laser machining, and laser machining systems, which include optics, positioning systems, manipulators, etc. The theoretical treatment of the laser includes a section on the basics of heat transfer and fluid mechanics, and analyses of one, two and three-dimensional laser machining processes. The book closes with a description of state-of-the-art laser machining applications in research and industrial practice.

Advances in Nonconventional Machining Processes

Bentham Science Publishers. 2020

In the modern era of manufacturing, unconventional machining methods are quite popular due to various advantages such as high accuracy, excellent surface finish, less tool wear, much quieter operations, among others. Moreover, new age and novel materials are sometimes hard to machine with traditional machining processes due to their high strength and brittleness. Advances in Nonconventional Machining Processes covers recent development in such methods. Chapters have been contributed by many authors and provide detailed information about machining processes (ultrasonic machining, thermally enhanced machining and electronic discharge machining, to name a few). Additional chapters that provide information about novel materials and their fabrication as well as innovations in machining methods (including the use of machine learning techniques) which have long been established on an industrial scale are also included in the book. Advances in Nonconventional Machining Processes is a reference work suitable for apprentices and academic scholars studying manufacturing. Industry professionals who wish to know about cutting-edge developments in machining techniques will also find this a useful handbook for their library.

This cutting-edge technology harnesses the concentrated energy of laser beams to precisely cut, etch, drill, or engrave a wide range of materials, from metals and plastics to ceramics and composites.

Principles of Laser Machining

At its core, laser machining capitalizes on the process of material removal through localized melting, vaporization, or chemical degradation induced by the intense heat generated by a focused laser beam. The laser's wavelength, power density, and pulse duration are meticulously controlled to optimize the interaction with the target material, ensuring accurate and consistent results.

Types of Laser Machining Processes

Laser machining encompasses several distinct processes, each tailored to specific applications and material requirements:

1. Laser Cutting: Utilized for intricate and precise cutting of sheet materials, laser cutting employs a high-powered laser beam to melt or vaporize the material along a predetermined path.
2. Laser Drilling: By creating precisely shaped holes in various materials, laser drilling finds applications in industries such as aerospace, automotive, and electronics.
3. Laser Engraving: This process involves selectively removing material from a surface to create intricate designs, patterns, or text, making it invaluable for marking, branding, and decorative applications.
4. Laser Welding: Leveraging the laser's concentrated heat, this process enables the fusion of similar or dissimilar materials with exceptional precision and minimal distortion.
