1. Statistical analysis of acoustic emission signals generated during turning of a metal matrix composite
Acoustic emission technique (AET) has been used to monitor the progress of tool wear during turning of silicon carbide (20 wt.%) dispersed Al alloy metal matrix composite. Acoustic emission (AE) signals generated beyond a specific cutting distance increase abruptly. Statistical analysis based on assumed β distribution of AE energy showed that skewness and k

2. Surface topography assessment techniques based on an in-process monitoring approach of tool wear and cutting force signature
One of the most influential sources in machining affecting surface roughness is the instantaneous state of tool edge. The main objective of the current work is to relate the in-process immeasurable cutting edge deformation and surface roughness to a more reliable easy-to-measure force signals using a robust non-linear time-dependent modeling regression techn

3. Tool wear monitoring in the milling process by acoustic emission / Monitoramento do desgaste de ferramenta no processo de fresamento via emissÃo acÃstica
The main goal of this work is the development of techniques for application of acoustic emission signal in tool wear monitoring in face milling operation. In this work a Sensis (DM 42) equipment for acquisition of the acoustic emission signal was used during the milling of a high strength low alloy steel (Din 38MnS6). A milling cutter with 125 mm diameter fo

5. Diagnostic of turning pperation of ABNT 304 stainless steel through chip analysis / Diagnóstico do processo de torneamento do aço inoxidável ABNT 304 a partir do estudo da formação do cavaco
Os aços inoxidáveis são materiais que apresentam em geral baixa usinabilidade devido principalmente à alta taxa de encruamento durante a usinagem e produção de cavacos longos que levam a um desgaste acelerado da ferramenta. Por isso, torna-se importante identificar a relação entre a evolução do desgaste e a morfologia do cavaco. Foram realizados te

6. Monitoramento do corte de dentes de engrenagem com ferramenta hob via corrente eletrica do motor da maquina
This work is about the monitoring of the electrical current of the machine tool motor in production floor, used in cutting of gear teeth with HOB tools, aiming to verify the relationship between the cutter wear and electrical current. Based on this, the purpose is to check the feasibility of determining the moment to replace the tool using the value of the m
