Finite Element Explicit Comparative Analysis of Effect of Cutting Tools on Workpiece

Abstract

The orthogonal cutting process, used in metal machining, involves removing material from the workpiece as chips using a single-point cutting tool that contacts it with moderate force. Unwanted material is frequently removed from technical components using metal cutting procedures, which are also often employed to achieve dimensional precision and produce the proper level of surface polish. Therefore, this work focused on a comparative analysis of the effect of cutting tools on workpieces using finite element analysis. An explicit dynamic analysis of the study was carried out to ascertain the deformation, tension, and strain in the workpiece structure. For best performance and necessary materials, the material's qualities were carefully assessed, and the materials utilized for this study were vanadium, Tungsten, and molybdenum for the cutting tool, and steel V250, TI 6%AL4%V, Inconel 718 for the workpiece. To perform at their best, boundary conditions were specified. The study used an explicit dynamic processing module with the required setup and boundary conditions. The position where the corresponding stress occurs most frequently is where deformation will occur most frequently; from then on, material deformation will start to spread to other regions at long as there is a constant cutting effect. The area that experiences the maximum stress is where the cutting tool makes contact with the cutting substance. Tungsten is the most efficient cutting material for turning Inconel, steel V250, and Ti-6Al-4V. While Inconel has the highest tensile strength of any material, making it the most appropriate, having the best resistance to cutting impact.
