摘要
曲面交线、曲面内凹区域及曲面中浅平面的加工是曲面加工的难点。针对曲面加工中的补加工技术进行了详细的理论和工艺分析,对曲面交线、等高线补加工等的刀具轨迹生成算法进行了探讨,并在塑料瓶模具加工中进行了应用。
Surface intersections,concaves and shallow planes of the curved surface are difficult to machine.Detailed theoretical and technological analysis has been made on the clean-up machining technology for curved surfaces.The algorithms for generating the tool paths for surface-intersection and contour-line clean-up machining are stated.These algorithms have been applied in NC maˉchining of the mould for the plastic bottles.
