Surface integrity of PCD composites after EDM

Investigation of Surface integrity of AISI D3 tool steel After EDM

-AISI D3 tool steel is a high-carbon, highchromium, oil-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials. Typical applications for D3 tool steel include Blanking, stamping, and col...

Machinability behavior of PCD 1600 Grade Inserts on Turning AL/SiC/B4C Hybrid Metal Matrix Composites

Aluminium metal matrix composites reinforced with SiC and B4C particles are a unique class of advanced engineered materials that have been developed to use in high strength , high wear resistant and tribological applications. The conventional techniques of producing these composites have some drawbacks. In this study, the aluminium hybrid composite is fabricated using stir casting method. 10 % ...

Enhanced Composites Integrity Through Structural Health Monitoring

This paper discusses the topic of how the integrity of safety-critical structural composites can be enhanced by the use of structural health monitoring (SHM) techniques. The paper starts with a presentation of how the certification of flight-critical composite structures can be achieved within the framework of civil aviation safety authority requirements. Typical composites damage mechanisms, w...

Influence of EDM Characteristic Parameters on the Surface Microstructure in CK45 Alloy Steel

Electro Discharge Machining (EDM) is a very efficient machining process widely used in manufacturing components of complicated geometry. Based on its nature, i.e. material removal by electric discharge, the process induces thermal stresses that in turn result in generation of wide spread micro-cracks on the surface of the machined part. In this paper the influence of EDM characteristic paramete...
