Determination of optimal conditions of machining parameters is important to reduce the production cost and achieve the desired surface quality. This paper investigates the influence of cutting parameters on surface roughness and natural frequency in turning of aluminum alloy AA2024. The experiments were performed at the lathe machine using two different cutting tools made of AISI 5140 and carbi...

Chatter vibrations, occurring during cutting process, cause vibration between the cutting tool and workpiece, which deteriorates surface roughness and reduces tool life. The purpose of this study is to investigate the influence of cutting parameters and tool construction on surface roughness and vibration in turning of aluminum alloy AA2024. A new design of cutting tool is proposed, which is fi...

Resistance spot welding (RSW) has been used widely to join sheet metals. It has been a challenge to get required weld quality in spot welding of dissimilar thickness materials. Weld parameters are not generally available in standards for thickness beyond 4mm. This paper presents the welding process design and parameter optimization of RSW used in joining of low carbon steel sheet of thickness 0...

Sintering parameters of the SS316L water atomised inject ion moulded compact has been optimized for its best sintered density. The L9 (3 4 ) Taguchi orthogonal array is used in the experiment while sintering temperature, sintering time, heating rate and coofing rate was selected as factors that influenced the sintered density. The sintering environment was in the vacuum and four replications we...

The aim of this research is to investigate the optimization of cutting parameters (cutting speed, feed rate and depth of cut) for surface roughness and metal removal rate in turning of AISI 8620 steel using coated carbide insert. Experiments have been carried out based on Taguchi L9 standard orthogonal array design with three process parameters namely cutting speed, feed rate and depth of cut f...

The cylindrical grinding parameters on 304 stainless steel are conducted using Taguchi design of experiments of L9 orthogonal array was selected with 3 levels with 3 factors and output parameter of Surface Roughness is measured. The quality of the surface describes the relationship...

Abstract Friction stir welding is a solid state joining method used to join materials which cannot be joined by fusion welding. In this method, heat produced due the friction between tool and workpiece weld material. Heat input depends upon amount of caused process parameters such as rotational speed, geometry, axial force etc. present study, effect shoulder pin diameter ratio, speed on peak te...

A grey-based Taguchi method was applied to investigate the optimal operating conditions in shielded metal arc welding (SMAW) join SS316 and ASTM A36. This work aims set parameters for mechanical properties of weld joint. The effects various factors on electrode type, current, welding, speed have be characterized optimized achieve an optimum condition. An L9 orthogonal array used group component...

The aim of this investigation is to optimize the process parameters obtain minimum corrosion rate and weight loss Al/SiCp metal matrix composites. A Taguchi based grey relation analysis was carried out. such as number hours dipped in 3% NaCl solution, vol.% SiCp aging at 170°C for were considered. working range each fixed on low rate. test out using relationship analysis. Three factor three lev...

In the current paper, different methods of repairing a pre-cracked reinforced concrete beam (RCB) were reviewed and described briefly. Afterward, near-surface mounted (NSM) technique was used to simulate reinforcement RCB using carbon fiber polymer (CFRP) laminated layer. To do this end, Firstly, based on previous experimental analytical studies limitations dimensions specified, then Minitab so...
