FEM analysis of edge preparation for chamfered tools
International Journal of Material Forming, 2009The chamfer enhances the performance of the tool by strengthening the edge and reducing the possibility of tool wear and breakage. The strength of the chamfered tool can be investigated by analysis of process variables. This research investigates the effects of chamfer width and chamfer angle on process variables (force, stress, tool temperature and ...

Vibration Polishing Edge Preparation for Cemented Carbide Inserts
Applied Mechanics and Materials, 2012Micro-cracks on cutting edge will cause early breakages on cutting tools, accelerate tool wear and reduce cemented carbide tool life. Edge preparation can improve the cutting edge quality. Vibration polishing experiments were carried out for cemented carbide inserts edge preparation.

Influence of Edge Preparation on Cutting Tool Wear
Applied Mechanics and Materials, 2012Edge preparation is not only the process of grinding proper geometry of cutting edge or removing micro-cracks on cutting edge region, but also a way of improving cutting tool life. In this study, cutting models with different cutting edge radius were set up with FEM software.

Customized cutting edge preparation by means of grinding
Precision Engineering, 2013Abstract Due to their low load resistance, sharp ground cutting edges are generally considered disadvantageous to high performance cutting processes. Consequently, providing additional cutting edge preparation in order to enhance tool-lifetime and – performance has become increasingly important.

Control of Built-Up Edge Behavior by Chamfered Cutting Edge Preparation and Surface Modification
Key Engineering Materials, 2012A chamfered cutting edge, which is commonly shaped in order to strengthen an edge of a cutting tool consisting of brittle material, easily causes an enhanced adhesion and a burr formation due to high compressive stress anterior to the edge. These problems lead to a detachment of tool material and a notch wear at depth-of-cut line, which would result in

Edge preparation of carbide tools with abrasive brushing method
2011 Second International Conference on Mechanic Automation and Control Engineering, 2011Edge preparation is a process to modify edge geometry and surface integrity of cutting tools. Cutting tools life can be improved by edge preparation. Edge preparation experiments of tungsten carbide tool were carried out with nylon abrasive brushes on lathe machine. Cutting tool edge surface was observed with optical microscope.
