“…A possible explanation of this behavior can be linked with the heat accumulation when drilling CFRP under dry cutting mode. CFRP material has generally low thermal conductivity and low heat capacity; as a result heat can be easily generated and accumulate in the cutting zone [47]. Literature [48] points out that glass transition temperature of CFRP is around 160-200°C.…”

Key composite made aerostructures such as fuselage inner walls, flap support fairings, empennage ribs, and the vertical fin ribs are comprised of non-vertical inclined and radial holes that join with other key metallic and non-metallic structures. Carbon fiber reinforced plastics (CFRP) are also used in the aerospace, automotive, marine, and sports-related applications due to their superior properties such as high strength to weight ratio, better fatigue, and high stiffness. CFRP drilling operation is different than the homogenous materials as the cutting-edge interacts with fiber and matrix simultaneously. Flank face of the tool rubs on the workpiece material and develops high frictional contact due to the elastic recovery of broken fibers. Lubrication during CFRP cutting can reduce the friction involved at tool-workpiece interface to enhance cutting performance. Dry cutting, cryogenic machining, and minimum quantity lubrication (MQL)-based strategies are termed as ecofriendly cooling/lubrication methods when machining high performance materials. The abrasive nature of carbon fiber is responsible of producing cutting forces which leads to different types of imperfections such as delamination, uncut fiber, fiber breakout, and fiber pullout. The integrity of CFRP drilled hole especially at the entry and exit of the hole plays a significant role towards the overall service life. The presented paper aims to characterize the interrelationships between hole inclination, lubrication/cooling methods, tool coating, and drill geometry with inclined hole bore surface quality and integrity during drilling of CFRP laminates. In dry cutting, thrust forces were found 2.38 times higher in the 30° inclination when compared with the reference 90° conventional inclination angle. Compressed air provided lowest increase (1.46 times) in the thrust forces for 30° inclination.

“…So we concluded that most of the researcher have focused on material removal along with some researchers have coted some material with magnetic abrasive particle as wire magnetic and induction free abrasive wire sawing (MIFAWS) is one of the method by which Chunyan Yao et al have prepared magnetic abrasive particle layer on the wire surface and then thickness was calculated for to find out how much magnetic Process was analyzed by MATLAB and results are discussed in detail for developing new areas of research [1]. The model used for machining is thermo-physical [24,25,26], electro-mechanical and thermo-electrical [27,28,29,30]. EDM and WEDM process is used for some complicated and tough to machine work pieces and for these machines the numerical model is created to analyses the process parameters for optimization [4,6,14,17], and for semi observational data [19,20].…”

The work reviewed here an overview of the current investigates about the machining of Aluminum metal matrix composite (MMC) which is major concern now a day’s industry. There is an increase demand of the development of advanced metals for many industrial applications, to complete such demands metal matrix composites are the right solution. Metal Matrix Composites (MMCs) have higher strength to weight ratio and their properties may be tailored as per the industrial requirements. The main purpose of machining is to produce a product of desired shape and size with specific quality and surface finish by removing a material in the shape of chips and it is affected by cutting parameters like feed rate and depth of cut also the selection of cutting tool plays a major role. However, MMC’s are highly abrasive and tools can wear rapidly, machining of these materials attracted researchers and industrial community a lot. So various tooling systems like Carbides, either plain or coated for tool of milling, drilling, and non-traditional methods of machining are also use to achieve the high durability, dimensional tolerances, functional requirements and surface quality of such materials after machining of MMCs. After machining analysis of the experimental data collected from various combination of analysis, methods are to be uses as ANN artificial neural network, analysis of variance (ANOVA) and TELBO techniques and Multilayer perceptron model will be constructed. On completion of the test, the techniques are to be used in authenticate the result found and to expect the behavior of the system.

Investigation on the Edge Chipping in Ultrasonic Assisted Sawing of Monocrystalline Silicon

et al. 2019

Monocrystalline silicon is an important semiconductor material and occupies a large part of the market demand. However, as a hard-brittle material, monocrystalline silicon is extremely prone to happen edge chipping during sawing processing. The edge chipping seriously affects the quality and performance of silicon wafers. In this paper, both conventional and ultrasonicassisted sawing tests were carried out on monocrystalline silicon to study the formation mechanism of edge chipping. The shape and size of edge chipping after sawing process were observed and measured. The experimental results demonstrated that different sawing processes present different material removal modes and edge quality. The mode of crack propagation was continuous cracks in conventional sawing process, while the expansion mode in ultrasonic assisted sawing was blasting microcracks. This results in the cutting force of ultrasonic assisted sawing becomes much smaller than that of conventional sawing process, which can reduce the size of edge chipping and improve the quality of machined surface.
