Available in PDF, EPUB and Kindle. Book excerpt: There is growing demand for micro and meso scale devices with applications in the field of optics, semiconductor and bio-medical fields. In response to this demand, mechanical micro-cutting (e.g. micro-milling) is emerging as a viable alternative to lithography based micromachining techniques. Mechanical micromachining methods are capable of generating three-dimensional free-form surfaces to sub-micron level precision and micron level accuracies in a wide range of materials including common engineering alloys. However, certain factors limit the types of workpiece materials that can be processed using mechanical micromachining methods. For difficult-to-machine materials such as tool and die steels, limited machine-tool system stiffness and low tool flexural strength are major impediments to the use of mechanical micromachining methods.

Available in PDF, EPUB and Kindle. Book excerpt: LASER-ASSISTED MACHINING This unique book develops exhaustive engineering perceptions of different laser-assisted techniques, reviews the engineering context of different laser fabrication techniques, and describes the application of laser-assisted fabrication techniques. Lasers are essential in the area of material processing because they can produce coherent beams with little divergence. The fabrication process known as surface cladding includes joining (soldering, welding), material removal (laser-aided drilling, cutting, etc.), deformation (extrusion, bending), and material addition. Some remarkable advantages of laser-assisted material development include faster processing rates and preservation of essential alloying components. However, the lack of widespread understanding of various material phenomena and how laser parameters affect them prevents the technology from being widely accepted on an industrial scale. Among the subjects Laser-Assisted Machining covers include high-powered lasers in material processing applications, laser-based joining of metallic and non-metallic materials, direct laser cladding, laser surface processing, laser micro and nano processing, emerging laser materials processing techniques, solid-state lasers, laser cutting, drilling and piercing, laser welding, laser bending or forming, laser cleaning, laser automation and in-process sensing, femtosecond laser micromachining, laser-assisted micro-milling/grinding, laser-assisted jet electrochemical micro-machining, laser-assisted water jet micro-machining, hybrid laser-electrochemical micromachining process, quill and nonreciprocal ultrafast laser writing, laser surface engineering, ultrashort pulsed laser surface texturing, laser interference patterning systems, laser interference lithography, laser-guided discharge texturing. Audience The book will be used by researchers in the fields of manufacturing technology and materials science as well as engineers and high-level technicians for a better understanding of various innovative and novel techniques to cope with the need of micromachining, as well as microfabrication industries for successful implementation of microproduct manufacturing.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents an investigation of novel laser assisted micromachining processes that addresses the limitations of micromachining of hard-to-machine materials. Two different laser assisted approaches are used to machine hard metals and high strength ceramics. For hard metals, the basic approach involves localized thermal softening of the workpiece material by focusing a solid-state continuous wave near infra-red laser beam in front of the micro milling tool (end mills of 0.1 to 0.5 mm diameter). By suitably controlling the laser power, spot size and scan speed, it is possible to produce a sufficiently large reduction in the flow strength of the work material and consequently the cutting forces and tool deflections. A force model is developed to predict the cutting forces in Laser Assisted Micro Milling (LAMM) of hard metals. For high strength ceramics, the approach involves use of a two step process. In the first step, thermal cracks are generated in a confined volume by the steep thermal gradients generated by laser irradiation of the workpiece. In the second step, the weakened region is removed by a micro grinding tool. The characterization and modeling of the process serve as bases for users of the two approaches to select optimal process parameters.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last decades Laser Assisted Machining (LAM) of hard materials has grown into a viable solution for the manufacturing industry. Interest in the machining of ceramics has grown due to the possibilities of LAM reducing tool wear and increasing productivity. The concept is based on heating the ceramic material into a soft phase that makes it much easier to machine. The other advantage this technology has over traditional grinding is that is possible to make complex shapes and even machine threads. While there has been research in LAM of ceramics such as Silicon Nitride, Zirconia, Alumina it often lacks comprehensive analysis for a particular laser source. In order for industry to adopt such a technology an optimized approach to providing results on ceramics is required. A few years ago as a result of ongoing research at NIU the commercial technology Easy to Machine Hard Materials (EMHM(TM)) was developed to address this issue. While research of Silicon Nitride, Zirconia, Alumina and Cemented Carbide are ongoing via EMHM the thrust of this research will be to provide a comprehensive approach and reduce the time required to optimize parameters for machining ceramics. The main issue to address for productivity in industry (when machining) is how to minimize tool wear (so tools last longer) while removing as much material as quickly as possible. This will obviously vary based on material and energy available. To experimentally carry all this work out would require a vast amount of resources and time. As such this proposal discusses the development of an easy to use ANSYS simulation program that will enable the user to see the surface temperature (which can translate to tool life) based on the feed rate, depth of cut, laser power and spindle speed. There are complex thermo-mechanical forces at play and so an optimized program is required to improve throughput of the analysis. We will develop the first generation ANSYS simulation which will help us verify experimental work we have done with the materials that have been researched via EMHM(TM).
