摘要: AbstractIncreasing the efficiency of rough machining operations can produce significant productivity improvement in mould and die making because most metal is removed roughing stage. In this paper, a high-efficiency 2.5-dimensional milling strategy for core presented. The consists three different tool paths. first path generated on basis convex hull boundary region. Owing to absence concave segments, based eliminate chip load fluctuation problem encountered corner cutting. second an enhanced unidirectional straight-line path, which has virtue maintaining steady cutting resistance throughout. large staircases left behind by these two paths are refined using third contour-parallel that cuts layer upward manner. After applying paths, stock m...
