Abstract The manufacturing of parts from nickel-based superalloy, such as Inconel-800 alloy, represents a challenging task for industrial sites. Their performances can be enhanced by using smart cutting fluid approach considered sustainable alternative. Further, to innovate the cooling strategy, researchers proposed an improved strategy based on minimum quantity lubrication (MQL). It has advantage over flood because it allows better control its parameters (i.e., compressed air, fluid). In...

This work presents a finite element method (FEM) based micro-end milling cutting force modeling of Ti-6Al-4 V titanium alloy microchannels. is one the widely acceptable alloys for medical as well aerospace applications due to its advantageous properties like; corrosion resistance, larger strength weight ratio, non-toxic nature and bio-compatibility. Johnson-Cook constitutive equation used FEM model with consideration effects strain, strain rate temperature on material property failure...
This article experimentally studied the large nonlinear deformation of VHB 4910 elastomer by uniaxial tests. The study reveals that monotonic tensile stress-strain, hysteresis, cyclic stress softening, and multistep relaxation this exhibit rate-sensitivity. Toughness, failure stress, strain are shown to vary with rate. Maximum hysteresis loss, residual strains in loading-unloading, tests also be rate-sensitive. analytical models proposed predict certain important parameters, such as...
Abstract Dielectric elastomers (DEs) are gaining acceptance as potential actuator materials because of their exhibition a large amount deformation when stimulated by electrostatic forces. However, time‐dependent behaviour such creep and stress relaxation still pose great challenge for the design, modelling control DE‐based actuators. In this work, attempts made experimental estimation properties one most widely used dielectric acrylic elastomers, VHB 4910. Experimental investigation shows...
This work proposed an improved mechanistic model for prediction of cutting forces in micro-milling process. The combined influences tool run out, trochoidal trajectory the center, overlapping tooth, edge radius and minimum chip thickness are incorporated this to realize exact phenomenon. Moreover, undeformed algorithm has been presented by considering all passing teeth one complete revolution instead only current tooth trajectory. For estimation a based on geometry two fluted end mill cutter...
