Wedm Process

To improve strength to weight ratios, the fiber reinforced polymer composite materials are often used in conjunction with another material, like metals, to form hybrid structure. This paper reports the feasibility of using wire electrical discharge machining (WEDM) for cutting Titanium/Graphite Hybrid Composites (TiGr). Slit and slot cuts with WEDM process has been performed. Cutting times and process parameters were recorded, and cut surface characteristics were evaluated both with an optical and scanning electron microscopy (SEM). The results in terms of cutting time, workpiece material removal rate, and damage were presented and discussed. It was found that use of WEDM is possible for machining advanced hybrid metal composite laminates with appropriate machine settings.

Hole Machining

Based on a self-developed pulse power supply, effects of working fluid to machining efficiency and relative wear of electrode are studied. tangent-hole machining experiments are designed and carried out. Tangent holes with 0.75mm and 0.56mm diameters on some nozzles are obtained.
