Successful application of many implantable medical devices often depends on the technique used for attaching the devices to living tissue. Although mechanical attachment techniques that use micro-scale piercing elements are very promising, the fabrication of the micro-scale piercing elements poses considerable challenges. In this paper, the use of the mechanical micromilling process for fabrica...

Ultra-precision grinding using super abrasives such as diamond and Cubic Boron Nitride (CBN) is ideally suited to the production of artefacts in hard or brittle materials such as ceramics or hard metals. These materials are well suited to the production of moulds. Conventional ultra-precision machining techniques such as diamond turning or micro milling are of limited use in the production of t...

Iron insufficiency is a worldwide problem in human diets. In cereals like wheat, the bran layer of the grains is an important source of iron. However, the dietary availability of iron in wheat flour is limited due to the loss of the iron-rich bran during milling and processing and the presence of anti-nutrients like phytic acid that keep iron strongly chelated in the grain. The present study in...

For the micro-milling of hard and brittle materials, to avoid crack formation, a tool with ductile milling mode is required. Composite electrodeposition technology was used prepare Ni–diamond coating on surface brass. The microstructure, composition roughness were studied scanning electron microscope, X-ray diffractometer tester. adhesion strength by scratch test, wear resistance analyzed corro...

Abstract Focused ion beam (FIB) milling is an increasingly popular technique for fabricating micro-sized samples nanomechanical characterization. Previous investigations have cautioned that exposure to a gallium can significantly alter the mechanical behavior of materials. In present study, effects gallium, neon, and xenon ions are scrutinized. We demonstrate fracture toughness measurements on ...

Diamond tools are extensively used in ultra-precision machining due to their exceptional performance. However, when challenging materials like Ti6Al4V, diamond experience significant wear poor properties and catalytic effects. Tool not only impacts quality but also escalates costs energy consumption. Cutting fluids commonly employed mitigate interfacial reactions suppress tool wear. traditional...

This work aims at studying the effect of the milling conditions on the microstructure and mechanical properties of a ZrB₂-5 vol% Si₃N₄ matrix reinforced with chopped Hi-Nicalon SiC fibers. Several composites were obtained using different milling conditions in terms of time, speed and type of milling media. The composites were prepared from commercial powders, ball milled, dried and shaped, and ...

In todays manufacturing industry, high-speed milling plays an important role. The main benefits of high-speed milling over conventional milling are the high material removal rates with relatively low cutting forces. The efficiency of high-speed milling is limited by the occurrence of regenerative chatter. Chatter is an undesired instability phenomenon, causing excessive tool vibrations, reduced...

the rice industry to 1) estimate the milling yield that may be expected of rice lots when milled in large-scale milling systems and 2) produce milled rice samples from which visual, functional, sensory and nutritional assessments of the rice lot can be made. This chapter presents factors that can affect the laboratory measurement of rice milling yield, focusing on the use of the McGill #2 rice ...
