Cutting Edge Radius Effects on Diamond Coated Cutting Tools: From Deposition to Machining
ASME 2007 International Manufacturing Science and Engineering Conference, 2007Diamond coatings have been increasingly extended to cutting tool applications for machining advanced materials such high-silicon aluminum alloys. Diamond coating tool behaviors are interrelatedly influenced by both the coating and subsequent machining, and yet the tool edge geometry strongly impacts the stress fields around the cutting edge during each

Cutting temperature plays an important role in micro-scale cutting process because the dimension of the micro-milling cutter is relatively small and the wear of micro-milling cutter is sensitive to temperature. Considering the sidewall of a groove is formed by main cutting edge of the tool, and the bottom of a groove is formed by tool tip and the edge ...

INVESTIGATION OF CUTTING EDGE RADIUS OF HARDENED FLAT KNIVES AFTER PRODUCTION TESTS
Tekhnicheskiy servis mashin, 2023One of the important characteristics of flat knives is the radius of rounding of the cutting edge. The smaller the radius of rounding, the more efficient the cutting process is. With the help of various hardening methods, it is possible to reduce the wear of flat knives, so that the radius of rounding of the cutting edge will remain small for longer ...

Nose radius oblique tool: Cutting force and built-up edge prediction
International Journal of Machine Tools and Manufacture, 1996A semi-empirical machining theory is described for predicting cutting forces and temperatures for oblique nose radius tools from cutting conditions and a knowledge of work material flow stress and thermal properties. By defining an equivalent cutting edge based on the chip flow direction, predictions are made for different cutting conditions and tool ...

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).

Severe plastic deformation occurs in micro metal cutting process; meanwhile, new surfaces are generated due to the material separation caused by ductile fracture. The energy required for the formation of the new surfaces is of kJ/m2, which should not be neglected in the analysis of micro-cutting.

Influence of Cutting Edge Radius of Coated Tool in Orthogonal Cutting of Alloy Steel
AIP Conference Proceedings, 2004This paper investigates the effects of edge radius of a round‐edge PVD coated tool upon chip formation, cutting forces, and tool stresses in orthogonal cutting of an alloy steel 42CrMo4 (AISI 4142H). A comprehensive experimental approach based on end turning of thin‐walled tubes is conducted using advanced coated tools with well‐defined cutting edge ...

Abstract In micro cutting, both the cutting edge radius and the material grain size have a great influence on the cutting force. The study of the influence of the material grain size on the cutting force is unavoidably affected by the dual effect of the cutting edge radius. In this paper, a method for estimating the shearing force is proposed.

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
