    Abstract: The method of balancing the axial force of water pump by balance hole is taken as a research object. Based on the combined CFD technology and experimental research, the relationship between the radial position of balance hole and the effect of axial force, external characteristics of the pump is studied in-depth. Research shows that, the effect of ... Show More

    Abstract: Numerical simulation of milling process needs an accurate model of cutting tool. In this paper, we describe the methodology developed to design flat and ball end mills in three-dimensional configuration. The geometry of these cutters is issued from an analytic study based on oblique cutting theory. The described model is performed by using parametr... Show More
