“…The resulting stress state after machining is a combination of thermal and mechanical effects. It is known that the thermally dominant machining deformation leaves behind tensile residual stress in the machined surface, whereas mechanically dominant machining deformation induces compressive residual stress [1,3].…”

“…But it is also stamped under most difficult-to-cut materials mainly because of the poor machinability properties which are [1][2][3][4]: major strength retained during machining, high strain rate sensitive nature, readily work hardening characteristics, highly abrasive carbide particles in microstructure and poor thermal conductivity leading to high cutting temperatures. Attempts have been made in the past with due focus on surface integrity induced by turning operation of Inconel 718 considering the machining environment.…”

Abstract:This paper investigates the effect of material removal rate (MRR) and mainly machining environment on resultant surface integrity in high-speed machining (HSM) of Inconel 718. For this high-speed turning is carried out for three different cutting speeds, feedrates and depth of cut under dry, flood coolant and water vapour machining environments. The results show that flood cooling is ineffective in high-speed machining. Water vapours acts as a coolant and lubricant, and hence is highly effective in lowering surface roughness and surface damages in machining. However at very high material removal rates, dry machining seems to be an economical option. Under all the environments the residual stresses were found to be compressive in nature at all MRR levels. Keeping in view green manufacturing, good productivity and better quality, it is suggested that machining of Inconel 718 under water vapour environment is an ideal approach.

“…A time ago, Narutaki et al [3] studied the wear resistance of several ceramic tools during severe turning conditions up to 500 m/min. A complete state of the art in the field of ceramics and Inconel 718 machining can be found in Dudzinski et al [4], in which wear evolution was also considered. In order to define appropriate tool geometry and cutting conditions for such difficult to cut materials, intense research work under the concept of high speed machining (HSM) was performed, employing carbide tools in the turning process.…”

Difficult to cut materials such as nickel and titanium alloys are used in the aeronautical industry, the former alloys due to its heat-resistant behavior and the latter for the low weight -high strength ratio. Ceramic tools made out alumina with reinforce SiC whiskers are a choice in turning for roughing and semifinishing workpiece stages. Wear rate is high in the machining of these alloys, and consequently cutting forces tends to increase along one operation. This paper establishes the cutting force relation between work-piece and tool in the turning of such difficult-to-cut alloys by means of a mechanistic cutting force model that considers the tool wear effect. The cutting force model demonstrates the force sensitivity to the cutting engagement parameters (ap, f) when using ceramic inserts and wear is considered. Wear is introduced through a cutting time factor, being useful in real conditions taking into account that wear quickly appears in alloys machining. A good accuracy in the cutting force model coefficients is the key issue for an accurate prediction of turning forces, which could be used as criteria for tool replacement or as input for chatter or other models.

“…During its machining the cutting tool often gets subjected to very high thermal and mechanical loads which cause rapid tool wear. Welding and sticking of worked material onto the cutting tool is a major problem during machining of Inconel 718 which causes rigorous notching and high cutting forces generates vibration while machining [3][4][5]. Because of above reasons lot of research is going on in the field of machining of Inconel 718 using different techniques like Cryogenic machining, Air jet assisted machining, Ultra High Speed Machining.…”

Abstract:Optimization of process parameters for machining Heat Resistant Super Alloys (HRSA) is a very challenging task for researchers. Many techniques are being used to find out optimized process parameters for machining these alloys. This paper presents the use of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to optimize process parameters for High-Pressure Coolant (HPC) assisted turning of Inconel 718.Inconel 718 is one of heat resistance superalloy from nickel-chromium group suitable for aerospace applications.TOPSIS is used for optimization of manufacturing processes which involves analysis of multiperformance characteristics. In the present analysis, high-pressure coolant is introduced into the cutting zone while machining Inconel 718.The performance of the machining is optimized for response variables namely cutting force, radial force, feed force and surface roughness. It is seen from the analysis that TOPSIS is a very striking approach for multiobjective optimization which can be effectively used for machining processes which always involves many process parameters. Optimized process parameters found during the investigation are 80 bar coolant pressure, 60m/min cutting speed, 0.1 mm/rev feed and 0.5 mm of the depth of cut.
