飞机数字化钣金成形技术作业(CATIA数控加工与逆向工程)

1、飞机数字化钣金成形技术数控加工： SAU逆向工程：马鞍 班级： 学号： 姓名： 数控加工加工零件： SAU开始在坐标纸上画出“SAU”图形，单位关键点在CATIA中建立零件实体生成毛坯加工基本设置模拟加工判断生成NC代码结束第一部分：建立零件盒毛坯1， 在坐标纸上画出二维图形，并标出关键坐标，如图：2， 在CATIA，零件设计模块中建立实体，如图：3，进入Surface Machining模块用Create Rough Stock命令建立毛坯，如图：第一部分：加工模拟1， 切换到Prismatic Machining模块。如图：2， 双击Part Operating.1，设置如图：3， 加工“

2、S”槽，设置如图：4， 加工”A”槽、”U”槽设置类似上一步，不再一一截图5， 加工模拟效果如图：第三部分：生成NC代码1， 选项设置2，代码类型和保存路径设置2， 执行生成代码第四部分：查看代码1，生成的文件3， NC代码逆向工程：1，打开CATIA，开始->形状->Digitized Shape Editor模块3， 导入点云文件，如图4， 调整属性5，命令做网格线6，截取网格线上的点7，命令拟合为线段8，打开：开始->形状->创成式外形设计模块9，命令接合断开的线10，命令拟合曲面11，命令增厚曲面12，完成，保存文件附录：数控加工“SAU”NC代码%O1000N
