Micro-Cutting: basics and Applications comprehensively covers the cutting-edge study and engineering perform in micro/nano slicing: a space that's turning into more and more very important, specifically in glossy micro-manufacturing, ultraprecision production and excessive price manufacturing.

This booklet presents simple concept, layout and research of micro-toolings and machines, modelling equipment and methods, and built-in methods for micro-cutting. the elemental features, modelling, simulation and optimization of micro/nano slicing strategies are emphasised with specific connection with the predictabilty, producibility, repeatability and productiveness of producing at micro and nano scales.

The basics of micro/nano slicing are utilized to various machining methods together with diamond turning, micromilling, micro/nano grinding/polishing, ultraprecision machining, and the layout and implementation of micro/nano slicing approach chains and micromachining systems.

Key features
• includes contributions from top worldwide experts
• Covers the basic conception of micro-cutting
• provides functions in a number of machining processes
• contains examples of the way to enforce and observe micro-cutting for precision and micro-manufacturing

Micro-Cutting: basics and Applications is a perfect reference for production engineers, construction supervisors, tooling engineers, making plans and alertness engineers, in addition to desktop instrument designers. it's also an appropriate textbook for postgraduate scholars within the components of micro-manufacturing, micro-engineering and complicated production methods.

Example text

This force is perpendicular to the cutting force. 1) MRR vbd bd ( ) Where P is the rate at which energy is consumed in the cutting process in N · mm/s; MRR is the material removal rate, in mm3/s; v is the cutting speed in mm/s; b is the width of cut in mm; d is the uncut chip thickness. The specific cutting energy is a measure of the amount of work (energy) needed to remove a unit amount of material. For a constant width of cut b, cutting force Fc is normally proportional to uncut chip thickness, d.

One the other hand, as diamond has a very high affinity to iron, d­ iamond micro cutting is limited to the machining of non-ferrous materials such as aluminium and c­ opper. Tungsten carbide micro tools are widely used in micro cutting processes. Tungsten carbide has high strength and hardness. In order to increase the wear resistance and hardness, very fine grain size tungsten carbide is fabricated for micro tools and various coated micro tools, such as diamond and titanium coated tools, are becoming popular in micro cutting.
