Force prediction models for helical end milling of nickel-aluminium bronze

摘要: Nickel-aluminium bronze is used widely in seawater environment. The mechanistic method and analytical to predict helical end milling force are briefly described compared. approach shown depend on coefficients determined from tests. By contrast, the based a predictive machining theory, which regards workpiece material properties, tool geometry, cutting conditions types of as input data. Each edge cutter discretized into series infinitesimal elements along axis action equivalent classical oblique process. Thus, components applied each element can be calculated using model total instantaneous forces obtained by summing up contributed all edges. equation plane angle derivation through coordinate transformation. Experiments nickel-aluminium under different were conducted validate proposed model.
