5、料，厚度 3.98,如图7、 8。图7拉伸除料对话框 图8拉伸除料实体 说明为什么要 实体建模：实体造型的最显著的特点就是说表示物体的完整性与无二 义性，也就是说实体造型不但能完整而且能唯一的确定地表 示物体，并且包含了完整的信息。它能够更好的辅助机械制造，以保证所加工零件的精度要 求。所以要进行实体的造型。三、加工过程设计定义毛坯：参照模型，基准点为(-1000,-1000,0),大小为长、宽、高 分另I为 2000, 2000,200其他参数如图9。图9定义毛坯对话框定义起始点:坐标为（0,0,100）,如图10。图10定义刀具起始点对话框定义刀具：初选使用两把铳刀进行加工。D11用于粗加

6、工，D10用于精加工。D11主要参数：铳刀，刀具半径 80,刀角半径0。D10主要参数：铳刀，刀具半径 5,刀角半径0.其他参数如图11、12。图11刀具D11定义对话框 图12刀具D10定义对话框 粗加工轨迹生成1、对零件进行粗加工，选用等高线粗加工。主要加工参数：加工参数1:加工方向：顺铳，z切入层高3, xy切入行距40,切削模式环切，加工余量0.5,如图13。图13等高线粗加工加工参数1对话框 刀具参数：选用一D11。下刀方式：安全高度50,慢下刀距离10,退到距离10。如图14。图14等高线粗加工下刀方式对话框切削用量：主轴转速1500,慢下刀速度100,切入切由连接速度 350,切

7、削速度600,退刀速度100,如图15说明参数选取过程图15等高线粗加工切削用量对话框 和依据：粗加工参数的选择主要考虑切削的效率，选择大半径的铳刀便可以选择大进给量，选择大背吃刀量。都可以节省切削的时间，也可以简化程序。初选铳刀半径为80,为了使切削连贯进给量应小于铳刀直径，选择为40,又因为粗加工加工精度为 0.1即可，采用顺 铳方式精度更好一些，可以避免中间圆环部分切削不连贯。查资料可知，初加工背吃刀量不应超过5,所以选择3,以增加切削效率。加工余量设置为0.1。由于粗加工背吃刀量大，所以主轴应输由较大扭矩，选用较低转速1500,切削速度都应该选择低速， 故选择切入切由连接速度350,切

8、削速度600o下刀方式的设置是为了防止打刀。其他参数均采用默认。求得刀具轨迹如图图 16、17。图16粗加工刀具轨迹 图17粗加工刀具轨迹 仿真加工 模型如图18。图18粗加工仿真加工模型 精加工轨迹生成：对零件进行精加工，精加工方式选择扫描线精加工。主要加工参数:加工参数：加工方向往复，加工方法通常，xy方向行距2,加工顺序区域优先，加工精度为0.02,未精加工区不加工未精加工区域， 加工余量0。参数如图19。图19扫描线精加工加工参数对话框切削用量：主轴转速3000,慢下刀速100,切入切由连接速度 800,切 削速度1000,退刀速度100,如图20o图20扫描线精加工切削用量对话框下刀

9、方式：安全高度50,慢下刀距离10,退到距离10,如图21。图21扫描线精加工下刀方式对话框刀具参数：选择D10o其他参数均用默认。说明参数选取过程和依据：精加工参数的选择主要考虑零件的加工精度（形位误差， 表面粗糙度）。所以应选择较高的切削速度，小的背吃刀量和进给量。进给量应小于铳刀的直径故选择进给量为2,背吃刀量选择为0.5。这样可以保证零件的加工精度。使用扫描线精加工可以保证零件的几何精度o求得刀具轨迹如图 22 o图22精加工刀具轨迹 仿真加工模型如图 23 o图23精加工仿真加工模型四、生成数控加工代码和工艺文件：车床选择：机床选择参数如图 24。图24机床选择对话框 生成G代码：(
