This work presents the optimization while machining of Inconel superalloy as base material and copper as the electrode using ZNC electrical discharge machine with positive polarity. Formation of complex shapes by this material alloy with reasonable speed and surface finish is not an easy task with the traditional machining. Moreover, the edge profile (which is circular in this work) formed by the...
The current paper presents a collection of numerical, mathematical, and statistical techniques to predict strain behavior and required pressing force of 7075 aluminum alloy within the different parameters of equal-channel angular pressing (ECAP). Accordingly, response surface methodology was utilized to estimate the contribution percentage of the processing parameters (i.e., die channel angle, outer...
As the usage of plastic components has increased in various industries, the methods for fastening have increased rapidly. When the plastic components are fastened by self-tapping screws or bolts, failure occurs because of stripped threads or plastic creep. In these circumstances, threaded metal inserts provide improved joint performance and ability to assemble and disassemble the components without...
The present work attempts to determine the optimal engine load, fuel injection pressure (FIP), start of injection timing (SOI) and pilot-main injection intervals (PMII) regarding the performance and emissions of a diesel engine fueled with J20 biodiesel (20 vol% Jatropha curcas biodiesel + 80 vol% 0# diesel). A four-factor and three-level full factorial design and response surface methodology (RSM)...
The study aims to design and develop an integrated system to model and optimize the direct metal deposition process. Direct metal deposition is an emerging metal additive manufacturing technology, in which powder particles are melted using a high-energy laser source to consolidate a solid layer. With the aim to work with a variety of materials, process economy is an important consideration. Keeping...
Cut quality is an important factor in laser beam cutting. In the present paper, modeling and optimization of laser beam cutting process parameters during fiber laser cutting of A653 galvanized steel sheet for straight cut by using response surface methodology have been studied. In this experimental work, power, gas pressure, pulse frequency and feed were taken as input parameters and kerf width, kerf...
