“…This confirms the superiority of tools with −5 • SCEA when cutting hardened Stavax ESR tool steel with KT 315 and KC 9110 cutting tool material. This is because for a given feed and depth of cut, the area of cut is approximately constant, whilst the area of tool-chip engagement increases as the SCEA is changed from 0 • to −5 • [15]. This results in higher chip equivalent values, which lowers cutting temperature and increases tool life [16].…”

“…Ultrasonic machining is a valuable process for the precision machining of hard, brittle materials because of many of its unique characteristics. This machining process is nonthermal, non-chemical, non-electrical and creates no change in the metallurgical, chemical, or physical properties of the material machined [8]. Thus, in the present investigation, ultrasonic drilling (USD) has been chosen for further exploration as a machining process for alumina based ceramic materials.…”

This paper presents a study of the effect of process parameters on production accuracy obtained through ultrasonic drilling of holes in alumina based ceramics using silicon carbide abrasive. Production accuracy in ultrasonic drilling involves both dimensional accuracy (hole oversize) and form accuracy (out-ofroundness and conicity). The parameters considered are workpiece material, tool material, grit size of the abrasive, power rating and slurry concentration. Taguchi's optimization approach is used to obtain the optimal parameters. The significant parameters are also identified and their effect on oversize, out-of-roundness and conicity are studied. The results obtained are validated by conducting the confirmation experiments.

“…The maximum amplitude of vibration can be found at the resonant frequency of the crystal. In this case, the length of the crystal must equal half of the wavelength of the ultrasound wave in the crystal [3,4,49].

Drilling is a major machining process performed for assembly purposes in CFRP composite applications. Traditional methods of drilling CFRP composites (including twist drilling and its relative methods) have many machining problems such as short tool life, poor hole quality and low machining efficiency. There are critical needs to develop time-efficient and cost-effective processes for drilling CFRP composites. Rotary ultrasonic machining (RUM) can be one of them. This chapter presents RUM of CFRP composites, including definitions, features, machine elements (system set-up) as well as experimental and theoretical investigations. These investigations include effects of input variables (tool rotation speed, feed rate and ultrasonic power) on cutting force, torque, cutting temperature, edge quality, surface roughness, burning of machined surface, tool wear, material removal rate (MRR), power consumption and feasible regions during RUM of CFRP composites. Introduction CFRP composites Properties and applications of CFRP compositesFiber reinforced plastic composites can be classified into different categories based on the type of fibers. The fibers include glass fiber, carbon fiber (graphite fiber), polyethylene fiber, boron fiber, ceramic fiber and kevlar fiber [36].Carbon fiber reinforced plastic (CFRP) composites consist of two materials: carbon fibers and polymer. Within CFRP composites, the carbon fibers are surrounded in one or more orientations in a polymer matrix and can be in the form of small particles, whiskers or continuous filaments. The carbon fibers are used to support the load, while the polymer matrix is used to bind and protect the fibers and transfer the load to the reinforcing fibers [10,23,28]. The polymers used as the matrix of CFRP composites are generally classified as thermoset (epoxy, phenolic, polyester, etc.) or thermoplastic (polyether-ether-ketone, polyimide, etc.) resins [53].CFRP composites have a variety of attractive properties, including low density (lower than aluminum, providing light-weight engineering solutions); high stiffnessto-weight ratio (stiffer than titanium); excellent fatigue, corrosion and wear resistance; outstanding toughness and damage tolerance (enabled using proper fiber orientations); high dimensional stability; excellent chemical resistance (controlled by the polymer matrix); and low friction coefficient, thermal expansion, electrical conductivity [10,21,37,41,51,53].
