摘要
为减少铸造成型开模周期提高零件生产效率和质量,搭建了极坐标成型平台。阐述了极坐标相对直角坐标的优势,根据极坐标堆焊成型设备的结构综合逐点比较法及时间分割法,对极坐标下的圆弧插补算法进行了研究和探索,提出了极坐标模式下的逐点比较插补算法,对极坐标特有的插补特殊点和关键点的插补精度进行了优化,并编写可视化软件对插补过程仿真分析。最后设计圆筒插补实验通过对比得出该算法稳定可行。
In order to reduce the casting mold cycle and improve the production efficiency and quality of the parts, a polar coordinate welding forming equipment was developed. The advantage of polar coordinates rela-tive to rectangular coordinates is expounded, So we combines the structure of polar coordinate FDM equip-ment with the interpolation theory of the point by point comparison method to research and explore the arc interpolation algorithm in polar coordinates, we put forward a complete set of interpolation algorithm and op-timized the interpolation precision of the special points and the key points, and then simulate the interpolation process by visual software. Finally, the design of cylinder interpolation experiments show that the algorithm is stable and feasible.
