    Notes: The integration manufacturing technology is a kind of compound precision finishingprocess that combined grinding with abrasive jet finishing, in which inject slurry of abrasive andliquid solvent into grinding zone between grinding wheel and work surface under no radial feedcondition when workpiece grinding were accomplished. The abrasive particles are driven andenergized by the rotating grinding wheel and liquid hydrodynamic pressure and increased slurryspeed between grinding wheel and work surface to achieve micro removal finishing. In the paper,the machining process validity was verified by experimental investigation. Experiments wereperformed with plane grinder M7120 and workpiece material 40Cr steel which was ground with thesurface roughness mean values of Ra=0.6μm. The machined surface morphology was studied usingScanning Electron Microscope (SEM) and metallography microscope and microcosmic geometryparameters were measured with TALYSURF5 instrument respectively. The experimental resultsshow the novelty process method, not only can obviously diminish longitudinal geometry parametervalues of ground surface, but also can attain isotropy surface and uniformity veins at parallel andperpendicular machining direction. Furthermore, the finished surface has little comparabilitycompared to grinding machining surface and the process validity was verified

    Notes: To satisfy the increasing requirements in the collaborative development and pricequotation for injection mould from the customers and companies, this paper presents a web-basedcost estimation system of injection mould which can aid mould designers to evaluate the differentdesign alternatives, implement the collaborative development of injection mould, and provide areference for mould quotation. The overall architecture of the system based on a logical structure offour layers is established. Approach to cost estimation for injection mould is described in detail.Furthermore, a java-enabled solution together with the JESS 4.4 expert system shell and MicrosoftAccess 2000 is employed to develop such a networked cost estimation system. Finally, an actualexample is given to demonstrate the use of the online cost estimation system of injection mould. Thepractical results from engineering application indicate the system can provide an effective andfeasible tool to aid the evaluation of design alternatives and price quotation at the early developmentstages of injection mould

    An Integrated Modeling Method for an Engine Cylinder Body Based on Cross-Sectional Imaging System (2007)
    s.l. ; Stafa-Zurich, Switzerland
    Applied mechanics and materials Vol. 10-12 (Dec. 2007), p. 697-701

    Notes: This paper proposes a novel integrated modeling method based on cross-sectionalimaging system which can implement the rapid and low-cost development for various enginecylinder bodies. The integrated modeling method which involves four steps: object pre-processing,cross-sectional image acquisition, CAD model reconstruction and redesign, is presented.Furthermore, an engine cylinder body was used to demonstrate the application of the integratedmodeling method. The integrated modeling method proposed is characterized by simple process,short design cycle, and low-cost. It is particularly suitable for the 3D CAD modeling of an objectwith complex external and internal features. As a result, the method offers a good solution toimplement the CAD modeling for a variety of complex objects with undercuts, hidden and internalfeatures
