TOOL STRESS PATTERN DEPENDING ON TOOL GEOMETRY

International Journal of Modern Physics B, 2010
In metal cutting practices, for a given tool material, tool geometry is a very important element and must be carefully designed in relation to the workpiece material to be machined. Patterns of tool stress are varying with input cutting conditions; however, effects of tool geometry on tool stress are not clearly understood.

Cutting Tool Geometry and Tool Materials

1969
7.1 In this chapter some loosely connected aspects of metal cutting are discussed. Tool nomenclature has been dealt with first so that the various tool angles can be defined for use in the other sections. The direction of chip flow across the tool is next considered, to allow a concept of ‘effective’ rake to be established.

Tool geometry study in micromachining

Journal of Micromechanics and Microengineering, 2003
With the trend towards miniaturization, micromachining becomes more and more important in fabricating micro parts. Investigations have shown that unpredictable tool life and premature tool failure present a serious concern in micromachining. To further develop the process, a systematic study of various types of tool geometry has been carried out.

High-Strength Tool Geometry—A Result of Research in Tool Geometry

Journal of Engineering for Industry, 1964
A high-strength tool geometry has been developed as a result of research conducted in the Physical Research Department of the Cincinnati Milling Machine Company. This research was carried out with the purpose of overcoming difficulties in the machining of high-strength metals.

Tools from Differential Geometry

2016
In this chapter we introduce the necessary background in differential geometry of closed compact hypersurfaces in ℝ n . We investigate the differential geometric properties of embedded hypersurfaces in n-dimensional Euclidean space, introducing the notions of Weingarten tensor, principal curvatures, mean curvature, tubular neighbourhood, surface ...

New General Tools for Constrained Geometry Optimizations

Journal of Chemical Theory and Computation, 2005
A modification of the constrained geometry optimization method by Anglada and Bofill (Anglada, J. M.; Bofill, J. M. J. Comput. Chem. 1997, 18, 992-1003) is designed and implemented. The changes include the choice of projection, quasi-line-search, and the use of a Rational Function optimization approach rather than a reduced-restricted-quasi-Newton ...

Tools (Geometry and Material) and Tool Wear

2008
This chapter presents the basic definitions and visualisations of the major components of the cutting tool geometry important in the consideration of the machining process. The types and properties of modern tool materials are considered as well, as a closely related topic, as these properties define to a great extent the limitations on tool geometry ...

Adaptive Lathe Tools with Modified Geometry

Russian Engineering Research, 2019
© 2019, Allerton Press, Inc. Abstract: A design is proposed for the attachment of a replaceable polyhedral insert in the housing of a pass-through lathe cutter with two fixed positions of the insert. This design permits modification of the tool geometry.

Background: Relevant Tools from Geometry

2016
Shape spaces are typically nonlinear spaces where the rules of vector-space calculus do not apply directly. Instead, one uses tools from algebra, geometry, and functional analysis to develop frameworks for optimization and statistics in shape spaces.

Basic Tools of Riemannian Geometry

2017
In this chapter, we collect some material concerning Riemannian manifolds equipped with metric structures, and our choice of material presented is made for the applications to Carleman estimates and inverse problems in the succeeding chapters.
