Review of vibration-assisted machining
D.E. Brehl,Thomas A. Dow +1 more
TL;DR: In this paper, the basic kinematic relationships for 1D and 2D VAM (circular/elliptical tool path) are described and the periodic separation between the tool rake face and uncut material, characteristic of VAM, is related to observed reductions in machining forces and chip thickness.
Journal ArticleDOI
Cutting of Hardened Steel
TL;DR: In this article, an overview of the mechanisms of chip removal in hard cutting and the thermo-mechanical influence of the work area is presented. But the workpiece quality and economic efficiency of hard cutting processes in comparison with grinding are discussed.
Journal ArticleDOI
Finite element simulation of conventional and high speed machining of Ti6Al4V alloy
TL;DR: In this paper, a finite element analysis (FEA) of machining of TiAl6V4 both for conventional and high speed cutting regimes is presented, where cutting force, chip morphology and segmentation are taken into account due to their predominant roles to determine machinability and tool wear.
Journal ArticleDOI
Statistical analysis of surface roughness and cutting forces using response surface methodology in hard turning of AISI 52100 bearing steel with CBN tool
TL;DR: In this paper, the relationship between cutting parameters (cutting speed, feed rate and depth of cut) and machining output variables (surface roughness, cutting forces) through the response surface methodology (RSM) is analyzed and modeled.

Turning versus grinding: a comparison of surface integrity aspects and attainable accuracies
W. König,A. Berktold,K.-F. Koch +2 more
TL;DR: In this article, the effects of hard machining on surface integrity aspects and attainable accuracies are not well understood and compared to those which are ground, and the development in the area of high precision machining of hardened steels is presented.

New observations on the mechanism of chip formation when machining titanium alloys
R. Komanduri,B.F. von Turkovich +1 more
TL;DR: In this paper, the authors report some new findings towards the goal of understanding the mechanics of chip formation when machining Titanium and other aerospace structural superalloys, which is difficult to machine except at low cutting speeds because of rapid tool wear.
Journal ArticleDOI
Some clarifications on the mechanics of chip formation when machining titanium alloys
TL;DR: A critical review of the literature and machining studies on a Ti-(6Al-4V) work material at various speeds with the aid of high speed photography and in situ machining experiments inside a scanning electron microscope is presented in this paper.
Journal ArticleDOI
Machining of Hard Materials
TL;DR: In this paper, the machining of hardened ferrous alloys is discussed, including high-speed tool steels, die steels and bearing steels in their hardened condition (hardness: 50 to 70 Rc).
