Experimental Investigation on Surface Roughness and Vibration Parameters in Turning of EN8K steel using PTFE / Nylon66 Liners for Carbide Insert Cutting Tools IJTSRD


Reliable vibration reduction method is one of the important aspects for achieving a good dimensional accuracy and surface finish during turning operation in a manufacturing system. An effort is being made to minimize vibration in order to improvise surface finish and dimensional tolerance in lathe dry turning process by passive damping technique. In the present work, prediction is made to improve surface finish by reducing the vibration of cutting tool in Lathe using viscoelastic material PTFE and Polyamide 66 or Nylon 66 liners fitted at the base of tool holder. The objective of this project work is to investigate on Surface Roughness in Turning of EN8K steel using PTFE / Nylon66 Liners for Carbide Insert Cutting Tools determine the optimal setting of cutting parameters (speed(N) rpm, depth of cut(d) mm , feed(f)mm/rev ) of the tool to have a reduced tool vibration (in terms of peak acceleration) and surface roughness(Ra). In this work the experiment has been carried out in lathe dry turning (without using cutting fluid) of a commercially available EN8K Steel as a work material and carbide insert tool. The ranges of process cutting parameters are speed (750,500,350,275 rpm), federate (0.2,018,0.16,0.14 mm/rev), depth of cut (1.5,1.2,0.9,0.6mm). For this experiment Taguchi design of experiment was carried out for PTFE and Nylon liner to collect the data for surface roughness and tool vibration by employing Taguchiorthogonal array to conduct experiments in an organized manner. Analysis of variance (ANOVA) with Minitab 17 software is performed to optimize the parameters on turning operation. The result indicates that Surface finish is observed to improve with application of Nylon liner.
