Micro Wedm

Micro wire electrical discharge machining (Micro-WEDM) is one key micro-processing technology for intricate micro parts. The surface texture is different with a single mechanical cutting surface and conventional spark-erosion formation machined surface. Assessment of the existing surface texture roughness parameters in terms of accuracy, or in the characterization of fine sense, can not meet the Micro-WEDM surface texture characterization needs. Through the analyses of surface autocorrelation function, structural shape ration, steepest attenuation autocorrelation function and surface texture direction, explicit the precise meaning of surface texture parameter characterization, make it really reflect the actual condition of Micro wire electrical discharge machining surface, modify Characterization Parameter algorithm, simplify the calculation process, make the results more accurate and more intuitive. Keywords: Micro wire electrical discharge machining; autocorrelation function; surface texture

Treatment Methods

The effects of textured tubes on the tribological performance in tube hydroforming (THF) are discussed. Textured surfaces, namely sand blasted, knurled, electrical discharge machined (EDM), and as rolled surfaces, were tested under various interface pressure conditions. Sand blasted textured tubes were found to have the best tribological performance. The study has demonstrated that the increase in the interface pressure between the tube and the die can result in either lower or higher interface friction depending on the surface texture conditions. The study has also shown that different surface texture treatment methods can alter the hardness of the tube surface with significant influence on the tribological performance.

Abstract This article investigates the surface texture transfer mechanisms in lubricated skin pass rolling of metal strips with three-dimensional rough surfaces of both regular patterns and random surface asperity distributions. Two important steps have been completed. The first is the successful establishment of an efficient numerical method for predicting the 3D texture transfer. It was identified that the new method can be used reliably with the key complex factors coupled in skin pass rolling, such as the effects of lubricant and surface roughness. The second is the exploration of the texture transfer mechanisms with the aid of this new method. In addition, the effects of hydrodynamic pressure on the texture transfer efficiency were comprehensively investigated by a dynamic explicit finite element analysis. It was found that lubrication plays a critical role in determining the surface texture transfer. The texture transfer ratio decreases with increasing the lubricant viscosity. A larger pressure coefficient brings about a lower texture transfer ratio, but a larger reduction ratio leads to a greater texture transfer.
