PSO for Selecting Cutting Tools Geometry
2008Today an extensive variety of cutting tool is available to suit different cutting situations and needs. Cutting tool selection is a very important subtask involved in process planning activities. This paper proposes the application of the particle swarm optimization (PSO) process for the definition of the optimal cutting tool geometry.

Tool Wear Prediction in Broaching Based on Tool Geometry
Volume 9: Manufacturing Materials and Metallurgy; Microturbines, Turbochargers, and Small Turbomachines; Oil & Gas Applications; Steam TurbineAbstract The aircraft engine is a safety-critical part of an aircraft. Constructive modifications resulting in ecological and economic improvements of the engine lead to necessary changes in manufacturing processes. The turbine discs in the low-pressure section are made of temperature resistant nickel-based superalloys.

Tool Geometry Solves Missile Machining Problems
Aircraft Engineering and Aerospace Technology, 1984A tool geometry, unique to Karl Hertel Ltd., of Nuneaton, is enabling British Aerospace to maintain continuous production of thin‐walled missile motor bodies. The workpiece material is a “difficult” extruded 4% copper‐aluminium alloy.

The Fundamental Geometry of Cutting Tools
Proceedings of the Institution of Mechanical Engineers, 1951A full geometrical analysis of a cutting tool edge is made, in which an effective rake of universal application is defined in terms of the primary rake and the angle of obliquity of the edge. The fundamental angles are related in an easy manner to the traditional workshop terms, and may readily be applied to any cutting tool.

Matrix Model Tools and Geometry of Moduli Spaces
Acta Applicandae Mathematica, 1997This is a survey of the author's results on discrete analogs of the moduli space \(\overline{\mathcal M}_{g,n}\) of compact Riemann surfaces with \(n\) marked points [see \textit{L. Chekhov}, J. Geom. Phys. 12, No. 3, 153-164 (1993; Zbl 0793.14015) and ``Matrix models for moduli spaces'', Commun. Math. Phys. (to appear)].

Linguistic Geometry tools generate optimal solutions
1996A formal theory introduced in this paper, the Linguistic Geometry, includes mathematical tools for knowledge representation and reasoning about multiagent discrete pursuit-evasion games. These class of games is an adequate mathematical model for the real world combat operations, particularly, for the aerospace and navy problem domains.
