以C919大飞机中央翼上下椽条的激光立体成形为研究对象，以激光立体成形扫描路径的工艺过程控制为目标，通过构建激光立体成形工艺参数的样式表达数据库，为椽条扫描路径设定不同的成形工艺参数。通过扫描路径的轮廓偏置生成矩形包围盒测试区域，结合“命中因子”自动判断下一层中相似扫描路径，从而为其指定相同的样式号。根据用户为不同路径设定的不同样式，自动生成激光立体成形数控作业文件。使用该方法实现了不同路径的不同成形工艺参数的设定，多层间样式自动继承，降低了工艺设计人员的操作负担，杜绝了加工过程中人为因素的影响，使工艺设计、数控操作职责明晰，满足了适航认证对激光立体成形过程控制的要求。

In order to fabricate an upper or lower chord blank of the C919 plane, different scanning paths are set with different laser solid forming (LSF) process parameters based on style-database of LSF. A test region is calculated using offset algorithm of the scanning path. “Similar scanning path” is automatically found by using parameters of the above test region and “hit probability” and a same style number is set for the next path. A numerical control operation file is automatically generated in terms of the style of every scanning path. What is concerned is how to set different process parameters for different scanning paths and transfer the style of the scanning path. Using this method, the operational complexity of process designer is reduced, and human factors are excluded during the manufacturing process. Processing design and manufacturing operation are separated and airworthiness certification requirements are satisfied.
