Influence of Cutting Edge Radius in Micromachining AISI D2
Applied Mechanics and Materials, 2013Chip formation is a dynamic process that is often non linear in nature. A chip may not form when the depth of cut is less than a minimum chip thickness. This paper presents an investigation of cutting edge radius effect on micromachining AISI D2 tool steel via simulation.

Investigation of the critical cutting edge radius based on material hardness
The International Journal of Advanced Manufacturing Technology, 2016This paper is aimed to investigate the influence of material hardness on the behaviour of cutting edge radius in tool-based micromachining process. The main governing process parameter considered for this study is relative tool sharpness (RTS) which is quantified as the ratio of undeformed chip thickness (a) to tool edge radius (r).

Influence of cutting edge radius on cutting forces in machining titanium
CIRP Annals, 2010Abstract The performance of machining titanium can be enhanced by using cutting tools with rounded cutting edges. In order to better understand the influence of rounded cutting edges and to improve the modelling of the machining process, their impact on active force components including ploughing forces and tool face friction is analysed.

Influence of cutting edge radius on tool life in milling inconel 718
AIP Conference Proceedings, 2019Nowadays, cutting tools manufacturing companies must improve their processes in order to satisfy the growing competitiveness. In fact, a hot topic among cutting tool manufacturers is to increase quality and repeatability. However, the technology and know-how used have reached a limit which slightly differences can suppose a high advantage to achieve ...

Effect of Rounded Cutting Edge Radius on Residual Stress within Machined Sublayer
Materials Science Forum, 2006A coupled thermal-mechanical model of plane-strain orthogonal metal cutting with continuous chip formation is developed to investigate the residual stresses in the finished workpiece. Deformation of the workpiece material is treated as elastic-viscoplastic with isotropic strain hardening, and the numerical solution accounts for coupling between plastic

Investigation on the ploughing force in microcutting considering the cutting edge radius
The International Journal of Advanced Manufacturing Technology, 2016Ploughing force is a parasitic force induced by the blunt cutting edge and the contact at flank face. Investigation on the ploughing force is necessary for the cutting mechanism understanding, the tool wear monitoring, and the tool sharpness evaluation.

Observations on cutting edge radius effects in cryogenic machining of porous tungsten
2015 IEEE International Vacuum Electronics Conference (IVEC), 2015Porous tungsten is a refractory metal commonly used to manufacture dispenser cathode pellets. To produce the required geometric shape of a cathode, precision machining of the emitting surface is necessary. Because dry machining leads to excessive tool wear and smearing of surface pores, a plastic infiltrant is used to both prevent smearing and ...

Study of micro ball end mill geometry and measurement of cutting edge radius
Precision Engineering, 2017Abstract Cutting edge radius plays an important role in conventional micro machining process, as it is of the same order as uncut chip thickness. Therefore it is important to measure the edge radius accurately. There is no recommended methodology, as of now, to measure edge radius of a ball end mill.

Modelling the cutting edge radius size effect for force prediction in micro milling
CIRP Annals, 2008This paper presents a theoretical model for cutting force prediction in micro milling, taking into account the cutting edge radius size effect, the tool run out and the deviation of the chip flow angle from the inclination angle. A parameterization according to the uncut chip thickness to cutting edge radius ratio is used for the parameters involved in
