Predicting Surface Roughness of AISI 4140 Steel in Hard Turning Process through Artificial Neural Network, Fuzzy Logic and Regression Models
In this study, the average surface roughness values obtained when turning AISI 4140 grade tempered steel with a hardness of 51 HRC, were modeled using fuzzy logic, artificial neural networks (ANN) and multi-regression equations. Input variables consisted of cutting speed (V), feed rate (f) and depth of cut (a) while output variable was surface roughness (Ra). Fuzzy logic and ANN models were dev...
متن کاملExperimental Study & Modeling of Surface Roughness in Turning of Hardened AISI 4340 Steel Using Coated Carbide Inserted
Turning of hardened steels using a single point cutting tool has replaced the cylindrical grinding now as it offers attractive benefits in terms of lower equipment costs, shorter set up time, fewer process setups, higher material removal rate, better surface quality and elimination of cutting fluids compared to cylindrical grinding. In order to obtain desired surface quality by machining, pr...
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...
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 کاملInfluence of Deep Cold Rolling and Low Plasticity Burnishing on Surface Hardness and Surface Roughness of AISI 4140 Steel
Deep cold rolling (DCR) and low plasticity burnishing (LPB) process are cold working processes, which easily produce a smooth and work-hardened surface by plastic deformation of surface irregularities. The present study focuses on the surface roughness and surface hardness aspects of AISI 4140 work material, using fractional factorial design of experiments. The assessment of the surface integri...
