    Abstract: By reasonable assumption and considering the friction, contact, preload intensity, load eccentricity, bolt bending, and other nonlinear factors, we establish three-dimensional finite element model for the high duty bolted joint to reflect the bolt behavior and develop the finite element calculation method for static strength, fatigue strength and related stresses of bolt. By this method, we do numerous numerical simulation experiments to study the effects of preload intensity, support plate thickness on the bolt behavior. These results will guide designer to complete the slewing bearing design effectively and accurately, and these research ideas can be well applied to bolted joints study in other devices.

    Abstract: After tool edges sharpen, there are a variety of micro-defects in the area of edge, which will accelerate tool wear and shorten tool life. In order to increase tool life and production efficiency, the area of edge strengthen was needed. In this paper, the electrolysis technology was used to enhance the cutting edge of high-speed steel(HSS) tap, the rounding of the edge region of the forming edge and surface morphology of cutting edge were investigated. And the tapping tests were carried on the Ti6Al4V. The results showed that electrolysis enhanced technology can eliminate the defects, invert a circular edge and improve the tool edge strength. The original tap was worn rapidly in the early stages of wear and the cutting force was changed big variation. The results showed that tap strengthened can reduce tool wear and improve tool life.

    Research on Cutting Force and Surface Roughness in Face Milling Ni-Based Superalloy
    Trans Tech Publications, Ltd. ; 2012

    Abstract: The machinability of Nickel-based superalloy GH4169 is poor, the traditional methods to machining is application of cutting fluids with the active additives which cause environmental pollution and health problems. In this paper, the water vapor was applied on milling instead of cutting fluids for the aim of green milling GH4169. The effects of water vapor, oil emulsion and dry cutting on milling force and the surface roughness have been examined with carbide tools YG6A. The results of experiments indicated that application of water vapor produced lower milling force, the values were reduced about 7 percent compared to dry cutting, and it is advantage in surface roughness. The research results show that clean production was achieved in metal cutting associated with water vapor cooling and lubricating.
