    摘要:

    机器人铣削加工技术是当前机器人技术发展的重要方向之一,而刀具轨迹的自动生成是实现机器人铣削加工的一个关键环节。以Open Cascade为几何造型技术开发平台,以改进的CC路径截面线法为轨迹生成方法,通过对约束面间距进行动态调整,改进了传统CC路径截面线法刀轨疏密不一致的问题,从而能够提高机器人铣削加工精度。在此基础上,开发出相应的CAD/CAM软件系统,实现了自由曲面精粗加工刀具轨迹的自动生成。最后,通过仿真和实验对生成的刀具轨迹进行了验证,验证了方法的可行性和准确性。

    Abstract:

    Robot milling process is an important developing direction of robot technology, and the automatic tool path generation method is the key step of its implementation. Open Cascade was used as the geometric developing platform, and the improved CC route section line method was used to generate the tool path. By adjusting the distance of constrain faces dynamically, the inhomogeneous problem of traditional CC route section line method of tool path was avoided, and the robot milling precision was improved. Based on the above, a corresponding computer aid design/computer aid manufacture (CAD/CAM) software system was developed. Tool path of rough and finish milling process for free form surfaces were generated through this system. At last, feasibility and accuracy of the tool path method are verified by simulation and experiment on generated tool path.
