A detailed investigation on the effects of cutting parameters and different cooling environments machinability austenitic stainless steel AISI 304 is presented in this study. The need for sustainable manufacturing better surface quality urged to explore merits cryogenic over other conventional techniques. end milling experiments were designed based three parameter three-level design considering dry, wet, machining have a comparative studies such as roughness, tool wear, forces, chip...

Metal foams and alloy are a novel class of engineering materials have numerous applications because their properties such as high energy absorption, light weight compressive strength. In the present study, methodology adopted to develop Ni-Cr foam is discussed. Polyurethane (PU) 40PPI (parts per inch) pore density was used precursor coating techniques electroless nickel plating (ELN), ultrasonic-assisted electroplating (UAEPN), pack cementation or chromizing were foam. The surface...

Surface integrity refers to the condition of workpiece surface modified by a manufacturing process. plays an equally important role in functional performance and quality components as dimensional accuracy, especially for applications such load-bearing energy absorbers. With rise additive technologies, where characteristics play are being manufactured combination process followed finishing A secondary machining is essential produced or powder metallurgy these processes exhibit poor finish,...

Surface texturing methods are used to engineer surfaces with specific properties in terms of wettability, friction, adhesion, or optical response. Hydrophobic surfaces, i.e., minimal have tremendous applications across various fields; however, for developing such over large areas complex geometries limited. This work investigates the process electrical discharge machining creating hydrophobic textures on stainless steel (SS304). The effect EDM parameters as current and tool feed surface...

Abstract An investigation was undertaken to determine the energy partition workpiece for grinding of an automotive nodular cast iron with a vitrified CBN wheel. The is critical parameter which needed calculating temperatures and predicting occurrence thermal damage workpiece. Straight surface experiments were conducted over wide range removal rates measure temperature response spindle power. Temperature matching analyses then applied in order obtain partition. Values found from 3 6% when at...

This study investigates about machining practices used worldwide for of Inconel 718 super alloy. The effect parameters like cutting speed, feed and depth cut on responses surface roughness material removal rate when end milling is studied using nine trials carried out based L9 orthogonal array. A Taguchi grey relational analysis was optimisation high operation 718. An variance (ANOVA) to find the most significant factor. Validation results through confirmation tests performed experimental...

Abstract Porosity is a major quality issue in additively manufactured (AM) materials due to improper selection of raw material or process parameters. While porosity kept minimum for structural applications, parts with intentional (engineered) find applications prosthetics, sound dampeners, mufflers, catalytic converters, electrodes, heat exchangers, filters, etc. During postprocessing additive components using secondary machining obtain required dimensional tolerance and/or surface quality,...

Thin film coatings TiSiN, TiAlSiN were deposited on WC-Co milling inserts using RF magnetron sputtering. The machinability studies of maraging steel is carried out thin TiSiN TiAlSiN. maching parameters cutting speed, feed rate and depth cut will be varied to analyse machining responses such as surface roughness force. performance each coating evaluated compared along with tool wear life. A Taguchi based grey relational analysis used optimize the variance (ANOVA) find most significant factor.

Sheet metal forming is a process where pieces of sheet are modified to their geometry rather than removing any materials. Major problems in operations the spring back effect and deformation errors. Spring very complicated behaviour not easy predict through mathematical models. It can only be controlled minimised but quite difficult eliminated. Different types materials used for aluminium mild steel its capabilities other properties. In this work, an experimental investigation stainless-steel...

Growing need for variety of micro-electro-mechanical systems necessitates advances in manufacturing technologies high volume production at low cost. In the bio-medical field, drug delivery is one areas that attract most attention MEMS because its potential to make less invasive, more precise and painful. A typical micro pump a device, which provides actuation source transfer fluid, this case, from reservoir body (tissue or blood vessel) with precision, accuracy reliability. Micro pumps are...
