Modifications of the Cutting Edge Geometry and Chip Formation in Milling

CIRP Annals, 1994
Summary The research describes the development of milling inserts with new cutting-edge geometries, three-dimensional chipformer configurations, and non-straight and non-continuous cutting edges. The investigation can lead to optimization of the cutting edge and the rake and clearance faces while improving tool life, accuracy, surface quality and ...

A study on the tool edge geometry effect on nano-cutting

The International Journal of Advanced Manufacturing Technology, 2017
The tool edge has a significant influence on a cutting process especially when it is comparable to uncut chip thickness. Generally, the cutting tool edge is considered rounded and is characterized by a tool edge radius. When the cutting tool edge geometry is not a symmetrical circle, the tool edge radius fitted with the former methods is not sufficient

An improved chip flow model considering cutting geometry variations based on the equivalent cutting edge method

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2003
An improved chip flow model of a nose-radiused cutting tool in oblique turning is developed considering cutting geometry variations based on the equivalent cutting edge method. The model-building procedure divided the arbitrary cutting area engaged with workpiece into a single edge and a nose-radiused cutting edge according to the depth of cut and ...

Cutting force model considering tool edge geometry for micro end milling process

Journal of Mechanical Science and Technology, 2008
The analysis of the cutting force in micro end milling plays an important role in characterizing the cutting process, as the tool wear and surface texture depend on the cutting forces. Because the depth of cut is larger than the tool edge radius in conventional cutting, the effect of the tool edge radius can be ignored.

Strip-tillage using rotating straight blades: Effect of cutting edge geometry on furrow parameters

Soil and Tillage Research, 2016
Abstract Efforts to develop strip-tillage drills for two-wheeled tractors have often used conventional bent rotary blades designed for full disturbance soil tillage which have resulted in poor furrow backfill and smeared furrows. This soil bin study examined the use of rotating straight blades with a range of cutting edge geometries for cutting a 50 ...

Study of micro ball end mill geometry and measurement of cutting edge radius

Precision Engineering, 2017
Abstract 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.

Influence of cutting edge geometry on tool wear performance in interrupted hard turning

Journal of Manufacturing Processes, 2015
Abstract Turning of hardened steels with interrupted surfaces presents some restrictions, due to the fact that the tools usually used have little resistance against the typical loads of interrupted cutting. In order to reduce tool wear, an appropriate combination of tool material and cutting edge preparation must be chosen. With the goal of finding a

Influence of cutting edge geometry and cutting parameters on surface finish in turn milling of aluminium matrix composites

Materialwissenschaft und Werkstofftechnik, 2010
AbstractDas Drehfräsen ist ein noch relativ gering verbreitetes spanendes Fertigungsverfahren zur präzisen Herstellung rotationssymmetrischer Formelemente, bei dem die Spanbildung durch eine Kombination der Rotationsbewegungen von Werkstück und Werkzeug erfolgt. Aufgrund der besonderen Kinematik weist das Drehfräsen großes Potenzial für die Bearbeitung

A systemic investigation of tool edge geometries and cutting parameters on cutting forces in turning of Inconel 718

The International Journal of Advanced Manufacturing Technology, 2019
In metal cutting process, size effects and edge effects have a significant influence on cutting forces and therefore on the machining performance. This paper facilitates those behaviors with different cutting tool geometry, i.e., round edge and chamfered edge, using analytical cutting force prediction models when turning Inconel 718 with round cutting ...
