“…It is one of the oldest and popular methods of metal cutting. It has even replaced grinding in several applications with reduced lead time without affecting the surface quality [21][22][23][24]. In this investigation; the experiments were carried out on a rigid CNC machine with spindle speed of 2500rpm.…”

In the present scenario of bulk manufacturing where Metal Removal Rate (MRR), Chip Thickness Ratio (CTR) and Surface Roughness (SR) is of significant importance in manufacturing the component using CNC (computer numerical controlled) machines. Nine experiments were conducted based on orthogonal array. General linear model has been generated for all the three output parameters such as (MRR, Chip Thickness Ratio surface roughness) versus input parameters (speed, time, depth of cut). The statistical method called the analysis of variance (ANOVA) is applied to find the critical factor. The Main effects of S/N ratio values are found and plotted in the form of graph. The optimized value is found for speed, time, and depth of cut by using “MINITAB” software. By using this optimized value the efficient metal cutting can be done in commercial mild steel.

“…In FSW, the rotating tool having specially designed pin [21] inserted into the abutting edges of workpiece and traversed to produce the joint [22]. During welding, the frictional heat, produced between the rotating tool surface and the surface of the metal sheet, is responsible for the plastic deformation of the workpiece material [22,23]. This localised heat softens the material around the tool pin.…”

“…In this work, AZ91 magnesium alloys have chosen due to its better industrial importance. Earlier, Kadigithala and Vanitha [27], Lee et al [28], and Kouadri-Henni and Barrallier [29] have studied friction stir welded joint of AZ91D magnesium alloy and observed mechanical and microstructural modifications in the various zones of the weld joint whereas, Rouhi et al [30] and Sevvel and Jaiganesh [23] have reported the FSW joining of AZ91C Mg alloys. Some researchers including Patel et al [31], Zhang and Wan [32] and Nakata [33] also ABSTRACT -The weight reduction concept is most effective to reduce the emissions of greenhouse gases from vehicles, which also improves fuel efficiency.…”

The weight reduction concept is most effective to reduce the emissions of greenhouse gases from vehicles, which also improves fuel efficiency. Amongst lightweight materials, magnesium alloys are attractive to the automotive sector as a structural material. Welding feasibility of magnesium alloys acts as an influential role in its usage for lightweight prospects. Friction stir welding (FSW) is an appropriate technique as compared to other welding techniques to join magnesium alloys. Field of friction stir welding is emerging in the current scenario. The friction stir welding technique has been selected to weld AZ91 magnesium alloys in the current research work. The microstructure and mechanical characteristics of the produced FSW butt joints have been investigated. Further, the influence of post welding heat treatment (at 260 °C for 1 h) on these properties has also been examined. Post welding heat treatment (PWHT) resulted in the improvement of the grain structure of weld zones which affected the mechanical performance of the joints. After heat treatment, the tensile strength and elongation of the joint increased by 12.6 % and 31.9 % respectively. It is proven that after PWHT, the microhardness of the stir zone reduced and a comparatively smoothened microhardness profile of the FSW joint obtained. No considerable variation in the location of the tensile fracture was witnessed after PWHT. The results show that the impact toughness of the weld joints further decreases after post welding heat treatment.

“…A rotating FSW tool, non consumable in nature, along with a pin and shoulder profile navigates in between the regions of the parent metal to be joined. When the FSW tool travels along the joint area, due to the friction between the FSW tool shoulder surface and the parent metal surface, heat is generated [6][7][8][9][10]. Apart from this, this FSW tool also leads to plastic deformation at the location of the joints, thereby enabling the joining of the parent metals, even when they are in the solid state.…”

An experimental investigation was conducted with the basic objective of demonstrating the feasibility of joining the AZ80A Mg alloys using the technique of friction stir welding (FSW). Good quality joints free from defects were obtained for 5mm thickness AZ80A Mg alloy flat plates at a speed of rotation of 750 rpm with a traversing speed of 1.5 mm/min, by employing a FSW tool fabricated out of M35 grade High Speed Steel(HSS). It was experimetally observed that, the nugget zone (NZ) of the defect free weldments were found with fine sized, equally spaced & uniformly distributed grains when compared with that of the parent metal. Apart from this, the heat affected zone (HAZ) lying beside the NZ was found to possess larger sized near equaxied grains due to the effect of annealing. The weld zones were found to possess regions of slight softening nature when compared to that of the parent metal, arising from the dislocation of the lower densities. Moreover, the tensile strength of the defect free weldments was found to be around 78% of the parent metal, which seems to better than that of the strengths obtained using conventional joining techniques.
