Investigation of the Relationship between Vibration, Cutting Forces and Tool Wear During the Processing of Inconel 718 Super Alloy under Coolant Pressure Jet-Assisted Turning with Variance Analysis

Abstract

In this study, cutter vibrations, wear conditions and cutting forces are observed during jet-assisted turning under coolant pressure conditions. Inconel 718 material is used as a thread. The data generated at cutting time is saved to a computer. Relationship between coolant pressure, vibration, tool wear and cutting forces is investigated with variance analysis. In variance analysis, Root Mean Square of vibration (vibration_RMS), RMS values of cutting forces and tool wear are chosen as dependent variables, and coolant pressure is chosen as independent variable. As a result of the analysis, it is found that the effect of coolant pressure on vibration is very important (P<0.01) on cutting forces and tool wear. Duncan multiple comparison test is applied after analysis of variance. According to the Duncan test results, it is observed that 100 bar cutting tests are the optimum tests under coolant pressure.
