摘　　要：现有的三维造型一般由AutoCAD和 3DSMAX等软件的图形导入而构建 ,修改复杂 ,且仿真实时性差。针对模具三维型面的机器人抛光 ,开发了面向对象的机器人抛光软件 ,以SCARA机器人抛光模具为例 ,研究了在Windows2 0 0 0平台下 ,采用VisualC ++6.0和OpenGL ,对机器人及工作场景进行三维实体造型 ,介绍了DXF格式文件的导入 ,NC文件的编译 ,以及机器运动轨迹生成及仿真。其中 ,机器人及场景的三维模型由所编写的函数直接生成 ,机器人运动控制代码则通过导入MasterCAM等数控软件绘制的工件图形和NC文件而生成。该系统的特点是具有实时仿真能力 ,且机器人尺寸及工作场景能在系统环境下随时修改 ,具有很强的适应性。Majority of 3-D model is generally constructed in term of the data imported from AutoCAD and 3DS MAX now, its disadvantages are: difficult to modify, bad real-time simulation performance. To polishing three dimension surface of mould & die with robot, we developed an OOP software for robot polishing, take the SCARA robot as an example, describe the 3-D solid shaping and modeling with Visual C++ 6.0 and OpenGL under Windows 2000 environment, introduce the importation of DXF file, compilation of NC code, the generation of robot trajectory and the simulation of robot motion. With OpenGL, the robot work scene and 3-D model can be generated using the system functions programmed by us; workpiece model was imported directly from the CAD/CAM software; the control codes of robot motion were generated in term of workpiece drawing and NC file. This system has a powerful real-time simulation capability, and the size of robot and work scene can be modified at any time under the system environment.
