【摘要】 内外圆磨床是具备先进制造能力的工业母机，其工艺丰富、机床结构复杂。针对内外圆磨床的加工过程，基于OSG(OpenSceneGraph)引擎搭建仿真框架；采用基于层次包围盒的碰撞检测算法，对沿数控程序加工轨迹运动的砂轮扫掠体和内外圆磨床各关键结构进行简化；最后，基于OCC(Open Cascade)和OSG开发，实现磨削仿真过程的防碰撞检查。更多还原

【Abstract】 This paper focuses on the machining process of the internal and external cylindrical grinding machine, building a simulation framework based on the OSG(OpenSceneGraph) engine. A collision detection algorithm based on hierarchical bounding boxes is employed to simplify the swept volume of the grinding wheel, which moves along the CNC program’s machining path, and the key structures of the grinding machine. Finally, collision detection during the grinding simulation process is implemented using a combination of OCC(Open Cascade) and OSG.更多还原
