In this experimental study, three TiB2/Al metal matrix composites (MMCs) with 40 μm in mean size were produced using a melt stirring squeeze casting route. Test was carried out to find the parameters influencing surface roughness (Ra) and material removal rate (MRR) on machining the TiB2 reinforced Al-6063 composite materials. The orthogonal array, the signal-to-noise ratio, and analysis of var...

A decorticating machine for Prosopis Africana was developed, tested and evaluated. Prosopis Africana is popular in the Sub-Saharan Africa, with all the parts of the tree useful for medicinal purposes. This study focuses on the threshing of the pod to obtain the seed, which is the most widely used of the parts of the Prosopis Africana tree. Results from preliminary investigations carried out of ...

A high strength nickel chromium alloy (50Cr-50Ni-Nb alloy), commonly referred to as IN-657, is specifically used for components in furnaces which are fired by low grade fuel oils containing high levels of vanadium, sodium and sulphur. The purpose of this study is to experimentally investigatethe effect of machining parameters on machinability in turning of Inconel 657. The considered parameters...

This work at ®rst look discusses the in¯uence of the tool path strategy on the cycle time of high-speed milling operations. Experiments and predictions were focused on pocketing operations with a zigzag tool path, quantifying the signi®cant discrepancy between the programmed feed rate and the actual average feed rate. A mechanistic approach for cycle time evaluation is proposed. The mechanistic...

This paper investigates the effect of different cutting parameters (cutting speed, feed rate, and depth of cut) on cutting force components and material removal rate (MRR) in dry and wet hard turning processes. The workpiece material, hardened alloy steel AISI 52100, was machined on a CNC lathe with coated carbide tool under different settings of cutting parameters. Three cutting parameters eac...

Machining can be outlined as the process of taking away material from a work piece in the grade of chips. During a machining process, isolated of the energy is turned into heat energy through the detritions yielded between the tool and the work piece and the plastic deformation of the work material in the machining zone. Turning is charmed by several constituents, for example, the cutting speed...

GAS TUNGSTEN ARC WELDING (GTAW) is the quality weld process. It is preferred welding process for stainless steel, low alloy steel, nickel, cobalt, titanium, aluminum, copper, and magnesium. The present work aims to evaluate the effect of Gas Tungsten Arc Welding process parameters on the quality of the weld bead. The process parameters Welding Current, Wire Diameter, Wire Feed Speed, Ratio of w...

Optimization of machining parameters for improving the machining efficiency is become important, when high capital cost NC machines have been employed for high precision and efficient machining. The strategy is to minimize the production time and cost by optimizing feed per tooth, speed, width of cut, depth of cut and tool diameter by satisfying all the constraints such as maximum machine power...

The surface finish was extensively studied in usual machining processes (turning, milling, and drilling). For these processes, the surface finish is strongly influenced by the cutting feed and the tool nose radius. However, a basic understanding of tool/surface finish interaction and residual stress generation has been lacking. This paper aims to investigate the surface finish and residual stre...

Manufacturing process primarily spotlights its objective as increasing productivity embedded with improved performance. In the scenario of contest between the sectors of industries, it is most important criteria to have an optimized performance in Machining parameters to have a better role of independence in owing to improve from better production to best production. In this task of Turning it ...
