This study presents a distributed parameter model for the transverse vibration analysis of a micro end mill. Owing to its geometrical nonuniformity, the micro end mill is spatially substructured into three distinct spinning elastic systems. With the application of the extended Hamilton''s principle to the energy expressions of the spinning elastic systems, the governing equations of each sub ...

The geometry of cutting flutes and the surfaces of end mills is one of the crucial parameters affecting the quality of the machining in the case of end milling. These are usually represented by twodimensional models. This paper describes in detail the methodology to model the geometry of a flat end mill in terms of threedimensional parameters.
Parametric Modeling Program of Fillet End Mill Jiapu Zhu Endmill cutter is the most commonly used cutting tool in metal machining industry, especially flat endmill and fillet endmill, which provide significant influence on machining efficiency and quality.
End mills (middle row in image) are those tools which have cutting teeth at one end, as well as on the sides. The words end mill are generally used to refer to flat bottomed cutters, but also include rounded cutters (referred to as ball nosed) and radiused cutters (referred to as bull nose, or torus).They are usually made from high speed steel or cemented carbide, and have one or more flutes.
The paper presents a mechanistic cutting force model of serrated end mill to predict cutting forces. Geometric model of serrated end mill is established, which covers variable helix end mill geometries. In this model, the serration of helical cutting flutes is expressed spatially and the wave of serration is defined to be a sine wave. The spatial vector is applied to define chip thickness so ...
