Abstract:

This thesis is about the application of the Wigner distribution to cutting tool monitoring and control. After reviewing traditional methods, a new method is proposed. This is to regard the surface texture and geometric error of form of a machined workpiece as the fingerprint of a cutting process, to analyse it, and to extract cutting tool vibration information from it, which can then be used for cutting tool monitoring. In order to analyse the surface texture effectively, three analysing tools, i.e. the Fourier transform, the ambiguity function, the Wigner distribution (WD), are examined and c

Abstract:

A very important requirement of modern machining systems in an 'unmanned' factory is to change tools that have been subjected to wear or damage in time. The old tool change strategies are based on conservative estimates from the past tool wear data, hence tools can be replaced too early or too late. This can increase the production cost or endanger the quality of the products. An integrated tool condition monitoring system composed of multi-sensors, signal processing methodology and decision-making plans is a crucial requirement for automtic manufacturing processes.

Abstract:

This thesis relates to the application of Artificial Intelligence to tool wear monitoring. The main objective is to develop an intelligent condition monitoring system able to detect when a cutting tool is worn out. To accomplish this objective it is proposed to use a combined Expert System and Neural Network able to process data coming from external sensors and combine this with information from the knowledge base and thereafter estimate the wear state of the tool. The novelty of this work is mainly associatedw ith the configurationo f the proposeds ystem. With the combination of sensor-baseid

Abstract:

Milling is a widely used cutting process, most commonly applied to machining external surfaces of workpieces. When machining operations are required within hard to reach areas of components, or deep within the bore of components, alternative methods of metal removal are generally employed. Typically when milling at extended reaches, difficulties may increase exponentially when trying to achieve distances several meters into a component. Essentially every topic of the milling process becomes difficult and more convoluted. Firstly to generate a stable cutting condition, and ultimately for an ope

Abstract:

The aim of this thesis is to propose a single-purpose stepped cutting tool for the drilling of the cylinder head. The thesis first introduces the current production of the cylinder head, including the description of the cutting conditions and the machines and tools used in the production process. The second part of the thesis is focused on the drilling of a three-step hole for which a step drill bit is proposed. The proposal describes the development of the drill bit, heat treatment, the method of clamping, the replaceable cutting tips used in the production process, additions for further mach

Abstract:

Les travaux présentés dans cette thèse s’inscrivent dans le contexte de l’identification de l’influence des paramètres de coupe et géométries d’outil sur l’usinabilité de l’alliage de titane Ti-6Al-4V sous deux états cristallographiques : alpha\beta et beta et s’insèrent dans le projet TiMaS, en partenariat avec Airbus et Figeac Aéro. La première partie consiste donc en une identification des différents critères d’usinabilité considérés dans la bibliographie pour l’usinage des titanes et la modélisation des actions thermomécaniques régissant la coupe. Dans une deuxième partie, l’usinabilité de

Abstract:

The dissertation is focused on the bearing production technology issues. The aim of the thesis is to investigate and evaluate the influence of the technological processes on properties of the functional surfaces of an outer bearing ring. The development, rolling, grinding and turning have been selected as basic technological processes. The subject of the surface integrity research on test samples is the measurement and analysis of the quality of the machined surfaces and residual stresses in the surface layers of the bearing rings. The comparison is made in relation to the previous operations

Abstract:

This master‘s thesis deals with optimization of cutting conditions when machining of precise parts in mass production. In experimental part of this thesis is a comparison of the roughing tool with indexable cutting inserts with the new implemented milling cutter. Tool wear of both roughing tools has been analysed. The surface roughness analysis after machining with the face milling cutter was performed. The output of this work is to obtain optimal cutting conditions to gain a minimum surface roughness.
