Ti-6Al-4 V alloy is mostly used in biomedical and aerospace industries, as well as in automotive and cutting implements, like scissors and knives due to its high strength-to-weight ratio and...
In this context, this work investigates the surface quality of the Ti-6Al-4V alloy in terms of surface roughness e microhardness, after surface grinding with silicon carbide wheel under various cutting conditions. The morphology of the machined was also analyzed in a Scanning Electron Microscope to understand the cutting mechanisms.
Influence of grinding wheel conditioning on the grindability of Ti-6Al
From the analysis of the SEM images of the Ti-6Al-4 V ground surfaces with a SiC grinding wheel, it was possible to observe that when dressing the grinding wheel with an overlap ratio, Ud = 3, in both adopted dressing infeed conditions, ad = 20 m, Fig. 9a, and ad = 40 m, Fig. 9b, the ground surfaces of the Ti-6Al-4 V samples showed a very
This paper investigates the machinability of Ti-6Al-4V in conventional surface grinding using silicon carbide abrasive which includes grinding force, specific grinding energy, surface topography, surface residual stress, and metallurgical structure alteration.
Grindability evaluation and tool wear during grinding of Ti
This article aims at providing a fundamental performance evaluation when grinding Ti 2 AlNb intermetallics using SiC abrasive. The wheel speed is fixed at 20 m/s while a range of depth of cut (5–20 μm) and workpiece infeed speed (3–12 m/min) are applied.
Considering extensive aerospace applications, Titanium alloy Ti-6Al-4V is considered as the work material and diamond as abrasive material for present simulations. Mechanical properties of work material and grinding wheels used, both for segmented -intermittent cutting as well as conventional grinding, are presented in Table 1. Table 1.

A finite element model of single-grain surface grinding of Ti-6Al-4V titanium alloy has been established, which takes into consideration of the actual variation of cutting depth along the grinding path. The effects of both the grinding speed and actual cutting depth on the grinding forces and stresses distribution were analyzed. Formation of the discontinuous lamellar structure chips in single
In this sense, the present work aimed to evaluate the effects of different dressing conditions of a SiC grinding wheel on the surface integrity of the Ti-6Al-4V alloy. A fliesen...
A comparative study of conventional SiC and superabrasive cBN grinding
Therefore, in the present study grinding of Ti-6Al-4V was carried out using superabrasive cBN wheel and conventional SiC wheel and the performance of them was compared. Grinding forces,...
The machinability of titanium alloys (Ti-6Al-4V) have been reviewed in many publications recently special grinding and mill-ing as these are among the key processes for the production of compressor and turbine blades for jet engine, where high heat resistance materials are preferred.
