Prediction 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 کاملOptimization 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 ...
متن کاملSurface integrity predictions and optimisation of machining conditions in the turning of AISI H13 tool steel
Surface integrity (SI) plays a very important role in functional performance. It is dependent on a large number of machining parameters. The major concern of industry is to know which combination of machining parameters provides the best SI of machined components. Traditionally, surface roughness is considered to be the principal parameter to assess the SI of a machined part. However, residual ...
متن کاملSurface Residual Stresses in Dry Turning of 0.45% C Steel
Residual stresses in a surface layer determine many exploitation characteristics of machined surface. Depending on their kind and the type of applied loading, the influence of residual stresses can be negative or positive. Tensile residual stresses usually exert highly detrimental impact on several functional aspects such as strength, fatigue life, corrosion, wear resistance, etc., whereas comp...
متن کاملExperimental Investigation of surface roughness in dry turning of AISI 4340 alloy steel using PVD- and CVD- coated carbide inserts
The performance of coated inserts was described using Response Surface Methodology (RSM) when turning AISI 4340 alloy steel using single layer PVD and triple layer CVD coated inserts. Cutting tests were performed under dry cutting conditions so as to reduce the effects of cooling agents on the environment. Surface roughness (Ra) was the main response variable investigated. The experimental plan...
