This study evaluated the cyclic fatigue resistance for six types of 25# NiTi instruments. A traditional manufacturing instrument, an M wire a gold treatment controlled memory (CM) CM instrument with electrical discharge machining (EDM), and R-phase heat were operated in different curved artificial canals. The fracture time (FT) number cycles to (NCF) instruments higher at 45° angles double-curv...

Abstract Titanium alloy Ti6Al4V is widely used in aerospace, shipbuilding, petrochemical, and other industrial fields. Low-speed wire-cut electrical discharge machining (LS-WEDM) has the advantage of high accuracy. However, there are few research studies on comprehensive effects parameters TC4 (Ti6Al4V) made by LS-WEDM surface. This paper focuses titanium investigates surface roughness, kerf wi...

Electrical discharge machining (EDM) can use soft tool electrodes to process hard workpieces achieve “soft against hard”, because it directly uses electrical energy and thermal remove metal materials. Then, generate complex features on harder materials meet the requirements of excellent surface quality. Since EDM involves many parameters, including non-electrical properties, is essential optimi...

Wireless signals are inherently generated during the spark discharges of micro-electro-discharge machining (μEDM). This work harnesses signals between 300-750 MHz for the monitoring of batch mode machining quality. In particular, the wireless spectra are used to sense incipient, debris-dominated machining that can be destructive to both the tool and the workpiece. Planar stainless steel (316L) ...

Abstract To increase the productivity and quality of machined components, wire electro-discharge machine parameters such as cutting speed, kerf width, surface roughness are often optimized. The Wire-electro discharge machining process generates a much higher temperature at wire-work piece interface which can potentially change metallurgical characteristics surface. This paper studies changes in...
