material as well as soft material by using multi- arrayed diamond tips and high speed spindle. Conventional machining method is too hard to control surface roughness and surface texture against brittle... were multi-array of diamond tips (n×n), speed of air spindle and feeding rate. The surface roughness and surface texture can be controlled by those parameters for micro machining. Key words: brittle......
was studied. The effects of the method on the corrosion resistance and the surface roughness of the anodic oxide films were evaluated using EIS technique. The morphology, component and roughness... distribution of current as a result of roughness and surface defects [22]. In addition, the empirical exponent of the constant-phase elements is related to the fracture dimension (DF) of the coarse surface......
substrate at deposition times of 5 min. The surface roughness of as-deposited copper films becomes rougher with large nodules as the deposition time increases. According to Fuchs–Sondheimer (F–S... plating; surface roughness; electrical resistivity 1 Introduction Copper has attracted considerable attention as an alternative material to aluminum and aluminum-based alloys due to its lower......
Effects of normal stress, surface roughness, and initial grain size on the microstructure of copper subjected to platen friction sliding deformationShan-quan Deng,Andrew-William Godfrey,Wei Liu,Cheng... normal stress, surface roughness, and initial grain size on the microstructure of pure Cu developed during platen friction sliding deformation(PFSD) processing were investigated. In each case......
surface morphology. Based on Gaussian filtering method, the original joint surfaces were divided into waviness surface and roughness surface, which can be analyzed separately. Then, the morphological evolution of joint surface subjected to shear loads was investigated by analyzing joint specific roughness coefficient (S) and joint surface degradation degree (Ds) quantitatively. The experimental results......
of specimens with different surface roughness were applied to investigate the effect of surface roughness on fatigue life. Furthermore, optical microscopy(OM) and scanning electron microscopy(SEM) were used... slightly in very high cycle regime, but is not horizontal for R=0.5. Fatigue limit appears after 108 cycles for R=0.7. Surface roughness (the maximum roughness is no more than 3 μm) has no influence......
by EDM process to increase the efficiency of material removal and reduce the surface roughness. In this study, the benefits of the hybrid process were determined as the machining performance of hybrid process was compared with that of the EDM in gas system. The main process parameters were varied to explore their effects on material removal rate, surface roughness and surface integrities......

South University Press and Springer-Verlag Berlin Heidelberg 2011 Abstract: The predictive model of surface roughness of the spiral bevel gear (SBG) tooth based on the least square support vector... was introduced to assess the effect of finishing parameters on the gear tooth surface roughness, and the training data was also obtained through experiments. The comparison between the predicted values......
