The hunt for environmentally friendly cutting fluids is underway as the problems of conventional become more evident. To achieve conscious machining, current study examines use Mango Kernel Seed Oil (MKSO) a fluid during turning AISI 1525 steel. According to 24 complete factorial techniques, vegetable-oil-based was produced by dissolving four different additives in mango kernel seed oil: emulsi...

 In the present study, an attempt has been made to experimentally investigate the effects of cutting parameters on cutting force in end milling of AISI 304 steel with solid carbide tools. Experiments were conducted based on four factors and five level central composite rotatable design. Mathematical model has been developed to predict the cutting forces in terms of cutting parameters such as he...

Metal matrix composites have been widely used in industries, especially aerospace industries, due to their excellent engineering properties. However, it is difficult to machine them because of the hardness and abrasive nature of reinforcement elements like silicon carbide particles (SiCp).In the present study, an attempt has been made to investigate the influence of spindle speed (N), feed rate...

One of the methods for making prototypes is incremental forming process. In this method, the forming tool, performs a pre-programmed movement by the CNC machine and runs the desired path. This modernization process is used in the automotive, aerospace, military, medical and other industries. One of the most influential parameters in this process is forming tool. This parameter is effective in f...

This study is an attempt to investigate the effect of welding rotational and traverse speed on mechanical and microstructural properties of A 430 stainless steel in order to give an effective processing window to achieve an appropriate microstructure and so mechanical properties. There are a wide range industrial uses for ferritic stainless steel. There from they have some problems like grain c...

Magnesium alloys, due to their attractive characteristics, are being utilized as lightweight structural materials in aerospace, automotive, and various other industries. Further design flexibility can be obtained by joining the Mg alloys with outstanding performance, such aluminum alloys. In this study, Al-6062 AZ31B have been joined through friction stir welding (FSW) using high-speed steel (H...

abstract gastrointestinal mesenchymal tumors are a group of tumors originating from the mesenchymal stem cells of the gi tract. digestive tract schwannomas are rare mesenchymal tumors which occur most frequently in the stomach. we report a 56-yearold woman who was examined endoscopically for dyspepsia which she had suffered from since 3 years ago. around gastric antral mass was seen. surgical r...

Aramid fiber-reinforced plastic (AFRP) composites are widely used in aerospace, rail transit, marine and military industries, due to their high specific strength, impact resistance, fatigue resistance excellent designable properties. In order meet different application requirements, cutting processes need be carried out, such as window opening, edge slit cutting. However, the characteristics of...

When chromosomes are being separated in preparation for cell division, their motions are slow (~16 nm/s) relative to the speed at which many motor enzymes can move their cellular cargoes (160–1000 nm/s and sometimes even faster) and at which microtubules depolymerize (~200 nm/s). Indeed, anaphase chromosome speeds are so slow that viscous drag puts little load on the mechanisms that generate th...
