Available in PDF, EPUB and Kindle. Book excerpt: Experiments were conducted to determine the critical depth of cut for machining of single crystal silicon carbide through Single Point Diamond Turning (SPDT) and fly-cutting, and of CVD coated Silicon Carbide through scratching. The ductile nature of these nominally hard and brittle materials is believed to be the result of a high pressure phase transformation, which generates a plastic zone of material that behaves in a metallic manner. The SPDT experiments have shown chip formation similar to that in metal machining. This metallic behavior is the basis for using AdvantEdge, metal machining simulation software, for comparison to experimental results. The cutting and thrust forces generated from the experiments and the simulations compared favorably when the simulation depth is below the critical depth of cut. The differences in the results that do arise are due to a difference in the actual simulated machining depth versus the expected machining depth as a result of workpiece deflection.

This book was released on 2010 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work was focused on the analysis of a new process called micro Laser Assisted Machining ([microm]-LAM). It is a ductile mode maching process being researched for machining of nominally hard and brittle ceramic and semiconductor materials like Silicon Carbide (SiC). Numerical simulations were conducted using the finite element metal machining software 'AdvantEdge' to study the material behavior during the [micron]-LAM process. The simulation model uses the pressure sensitive Drucker-Prager yield criterion to accommodate the material behavior due to a High Pressure Phase Transformation (HPPT). Various heating effects were created to mimic the actual machining process (laser heating and thermal softening). A realistic thermal softening curve was developed based on various references to simulate the thermal softening material behavior. A stress and temperature interaction study was done to idenitfy the relative (percentage) contribution due to pressure (and HPPT) and temperature (thermal softening) during the [micron]-LAM process. The cutting and thrust forces and the cutting pressures were compared at various temperatures of SiC to study the material behavior during th [micron]-LAM process.

Available in PDF, EPUB and Kindle. Book excerpt: MEMS devices are found in many of today’s electronic devices and systems, from air-bag sensors in cars to smart phones, embedded systems, etc. Increasingly, the reduction in dimensions has led to nanometer-scale devices, called NEMS. The plethora of applications on the commercial market speaks for itself, and especially for the highly precise manufacturing of silicon-based MEMS and NEMS. While this is a tremendous achievement, silicon as a material has some drawbacks, mainly in the area of mechanical fatigue and thermal properties. Silicon carbide (SiC), a well-known wide-bandgap semiconductor whose adoption in commercial products is experiening exponential growth, especially in the power electronics arena. While SiC MEMS have been around for decades, in this Special Issue we seek to capture both an overview of the devices that have been demonstrated to date, as well as bring new technologies and progress in the MEMS processing area to the forefront. Thus, this Special Issue seeks to showcase research papers, short communications, and review articles that focus on: (1) novel designs, fabrication, control, and modeling of SiC MEMS and NEMS based on all kinds of actuation mechanisms; and (2) new developments in applying SiC MEMS and NEMS in consumer electronics, optical communications, industry, medicine, agriculture, space, and defense.

Available in PDF, EPUB and Kindle. Book excerpt: Finishing is the final operation after a part is sized and shaped. Currently in high tech industries, there is a demand for nano level surface finishing of components. This process is done to improve the surface finish, to remove the recast layer, or to remove surface and sub-surface defects. The result is low friction, longer product life, and low power requirements. Equally important is the aesthetic aspect of the product. This subject is growing very fast from the technology as well as a science point of view. Books on this subject are very limited, particularly those ones that deal with both the science as well as the technology aspects.
