Diamond coated cutting tools have been pursued as a costeffective substitute to brazed polycrystalline diamond (PCD) tools in applications such as machining high-strength and lightweight materials. However, coating delamination has been known as the major failure mode of diamond coated tools, which terminates tool life prematurely. Once delamination failure occurs, the tool substrate often subj...

With the rapid development of high-precision-device technology, new demands are put forward for micro milling. The size effect and low cutting energy milling make process expensive difficult, especially Ti-6Al-4V alloys. wear micro-milling cutter lacks corresponding international standards its mechanism is complex. In this paper, four kinds cutters with different states were obtained by designi...

During the turning process of metastable austenitic steels, austenite is transformed into hard martensite by plastic deformation at low temperatures. This enables production components, which have both a hardened subsurface zone and ductile core. Cryogenic cooling allows to be during machining, leads shortening chain. However, effects such as wear can make it challenging adjust properties turni...

Abstract Several tool wear models for machining operations have been reported in the literature. However, most of them are capable modeling only a part curve, designed quasi-linear curves or need to be fitted by means differential equations. In this research, new analytical easy-to-use model is proposed, taking into consideration geometry cutting insert and influence speed tool-workpiece contac...

Tool wear monitoring is crucial for an automated machining system to maintain consistent quality of machined parts and prevent damage to the parts during the machining operation. A vision-based approach is presented for tool wear identification in finish turning using an adaptive resonance theory (ART2) neural network embedded with fuzzy classifiers. The proposed approach is established upon th...

Abstract Cutting tool condition is crucial in metal cutting. In-process failures significantly influences the surface roughness, power consumption, and process endurance. Industries are interested supervisory systems that anticipate health of tool. A methodology utilizes information to predict problems avoid must be embraced. In recent years, several machine learning-based predictive modelling ...

Inconel 718 has found use in many demanding applications due to its high temperature fatigue strength, hardness and low thermal conductivity . These material properties present a challenge productive quality (surface finish) machining promote rapid tool wear The work presented here describes the chip formation mechanisms of silicon nitride (Si 3 N 4 ) based ceramic SiAlON carbide whiskers reinf...

Abstract Implementing a magnetic field on the cutting area during machining process is one of ways to increase tool life, as result, reducing cost. Due this, numerous researchers conducted various studies in that field. However, there was no study which used permanent magnet has been found. In this study, effects life have investigated extensively with designed experimental setup. Experiments w...
