Performance improvement studies for cutting tools with perforated surface in turning of titanium alloy

Abstract

Abstract:In turning process, the cutting tool is essential for shaping materials. The cutting tools with various perforated surfaces help to increase the cutting tool life. Also, advances in CNC machining technologies have enhanced the productivity of machining process. One of the best or futuristic approaches in modern manufacturing engineering is the use of FEM Simulation for the metal cutting process. FEM simulation helps in understanding the metal deformation process and also helps in the reduction of experiments. The simulation helps the researchers to predict the major influencing cutting variable values without carrying out any experiment which is time-consuming and expensive. This research presents the simulation study of the performance of micro-hole patterned Polycrystalline Diamond cutting insert in machining Titanium alloy (Ti-6Al-4V). Micro-holes are drilled using Electrical Discharge Wire Drilling machine on the rake face of Polycrystalline Diamond (PCD) cutting inserts. FEM analysis is carried out to evaluate the effect of perforations on the mechanical integrity of insert. The micro-hole patterned insert is modeled in PRO-E modeler and simulated using DEFORM-3D software. The effective stress, strain, and temperature distribution are analyzed and the results are compared with the normal insert.

Influence of slide burnishing process on the surface characteristics of precipitation hardenable steel

“…Liquid nitrogen (LN 2 ) is one such coolant that has been efficiently used as a lubricant [2]. Some of the notable benefits of LN 2 are: it is environment-friendly, and also it does not have much impact on the operator [3,4]. The functional properties of the material can be improved after performing a slide burnishing operation using LN 2 as the coolant, and it has to be directed at the slide burnishing zone.…”
