Machining of EN31 Steel Using Carbide Insert - A Statistical Approach

EN31 steel is alloy martensitic chrome steel (equivalent to AISI 52100 steel). The material is frequently applied where the wear resistance or high surface loading is needed. In this experimental analysis, an attempt has been made to inspect the impact of process parameter in turning of EN31steel. The quality measures namely, surface roughness (SR) was a key property in the functional performance and accuracy evaluation of machined parts; tool wear (TW) is generally a gradual process due to regular operation, the wear depends on material used, tool shape, machining parameters, lubricants, machining tool characteristics etc., were investigated using Taguchi's method. The outcome reveals that Taguchi's technique used for minimizing the SR and TW. Finally, ANOVA concept is employed for finding relative significance in percentage contribution. Comparison of the results found from Taguchi method and experimental analysis does not show significant difference. (C) 2019 Elsevier Ltd. All rights reserved.
