Optimization of Surface Roughness in Hard Turning of AISI 4340 Steel using Coated Carbide Inserts
The use of multilayer coated carbide tool in hard turning has several advantages over grinding process such as; reduction of processing costs, increased productivity, short cycle time, compatible surface roughness and less enviornment problems without the use of cutting fluid. In the present study, an attempt has been made to evaluate the performance of multilayer coated carbide inserts during ...

15 صفحه اولPrediction of surface roughness during hard turning of AISI 4340 steel (69 HRC)
In this study, 39 sets of hard turning (HT) experimental trials were performed on a Mori-Seiki SL25Y (4-axis) computer numerical controlled (CNC) lathe to study the effect of cutting parameters in influencing the machined surface roughness. In all the trials, AISI 4340 steel workpiece (hardened up to 69 HRC) was machined with a commercially available CBN insert (Warren Tooling Limited, UK) unde...
متن کاملExpansion and fracture of AISI 1045 steel explosive-filled cylinders
By a improved front light-source framing photography technique and a simple fragments soft recovered method, the expansion and fracture behaviour of the AISI 1045 steel cylinders loaded by three different brisance explosives have been studied . Cylinders were heat treated-normalized and quenched and tempered. Experimental results show that the more intensive of the loading ,the stronger capabil...
متن کاملExperimental Study of Process Parameters in Dry Turning of AISI 4340 Alloy Steel Using PVD Coated Carbide Insert
CNC Turning is basically a material removal process done to obtain the desired diameter. Even though the machine tool industry has made tremendous progress, the metal cutting industries using various machine tools continue to suffer from major drawback of not utilizing the machine tools at their full potential. A major cause leading to such a situation is thought to be the failure to run the ma...
