Machining of superalloy Inconel 718 would have established some issues like, inability the tool materials to sustain for a longer duration due work hardening effect and very high cutting forces causes metallurgical damage on pieces. This research paper focuses life different associated with turning under conditions. Further, it is significant identify parameters that cause machining characteristics, in particular flank wear understand relationship they controllable parameters. Turning...

Electrical Discharge machining (EDM) is a non-conventional process, in general adopted to produce components with complex profiles that are difficult be achieved through conventional manufacturing processes. Since long, EDM widely used industries machine 'difficult materials' like HCHC steel (tool and die material). INCONEL 718 one of the alloys have relatively poor machinability processes, due its work-hardening nature, retention high strength at temperature (700 k) low thermal...

Researchers always focus their attention to bring out process improvements resulting in improved product quality and increased production simultaneously. Such efforts gain significance the case of Inconel 718, where cost saving producing components is higly rewarding. Turning experiments were conducted using Taguchi’s methods experimental data was collected. Response surface models generated for each response depicting role input variables effect interaction. Almost all research work...

For machining a component, it is important to understand the characteristics of work material in order choose appropriate cutting tool and fix set parameters achieve optimum output. Analytical models processes require complete understanding process mechanism hence are difficult be developed. Once developed, these useful parametric optimization, simulation, operation planning, parameter selection, analysis, performance prediction, verification experimental results, improving by...

Abstract A comprehensive test program was performed to experimentally investigate the effect of CFRP strengthening on axial strength and stability CFS plain angle short columns subjected monotonic compression. total 28 specimens were tested by varying configurations for different column heights. Both uni-directional (CF_UD) bi-directional (CF_BD) considered. The influence various parameters such as type CFRP, fiber orientation, number layers investigated discussed in detail. For single layer...

This paper discusses the methodology of developing models for turning process machining Inconel 718 alloy with coated carbide tool inserts.Approach through Genetic programming (GP) was aimed at an overall objective optimizing to yield higher metal removal, better surface quality and lower cutting forces.Taguchi's approach adopted design experiments accordingly were carried out, collecting experimental data in a controlled manner.Such grouped separately random training genetic (the developed...

Abstract The need for more efficient design has become a main concern to work with good range angle of attack (AOA) reduce the stall formation. In this project, two types NACA series airfoils i.e., symmetrical and asymmetrical profiles depending on their usage in various sectors are compared. profile is imported into ANSYS Fluent from data files. 2D geometry simulated under different wind velocitiesi.e., at 3m/s 15m/s respectively. graphs plotted comparing coefficients lift (C L ) drag D...

Attempts were made to gain a better understanding of the effects steel composition and thermophysical properties, such as solidus liquidus temperatures, heat oxidation, surface tension, viscosity thermal conductivity, on laser-cutting behavior. Laboratory-produced heats containing varying levels C, S, Si, Cu, Ni, Cr, Mo hot-rolled 32-mm-thick plates. Laser cutting was carried out after plates blanchard-ground 25 mm shot-blasted eliminate roughness variability. Under these conditions, Cu Ni...

Surface roughness and residual stress are considered to be major surface integrity issues that directly affect the quality life of components. The current research work highlights stresses induced while machining Inconel 718 with a range cutting parameters environments. Further, study aimed determine optimal parameters/conditions in terms speeds, tool materials conditions achieve better minimum values.
