4、模的实体模型并标注尺寸；对冲压头凹凸模实体模型进行粗加工；对冲压头凹凸模实体模型进行精加工；生成数控加工代码；生成工艺清单；加工仿真。其中R=24×10=240图1冲压头模具零件图二、 建立实体模型建立的模具尺寸如图2、3。图2模具尺寸图图3模具尺寸图造型过程：1、绘制草图0，正方形。如图4。图4建立正方形2、拉伸增料，深度16，如图5、6。图5拉伸增料对话框图6、拉伸增料实体3、在拉伸实体的一个表面绘制草图1，并拉伸除料，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

5、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、高分别为2000，2000,20。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：初选使用两把铣刀进行加工。D11用于粗加工，D10用于精加工。D11主要参数：铣刀，刀具半径80，刀角半径0。D10主要参数：铣刀，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

6、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：顺铣，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，切入切出连接速度350，切削速度600，退刀速度100，如图15。图15等高线粗加工切削用量对话框说明参数选取过程和依据：粗加工参数的选择主要考虑切削的效率，选择大半径的铣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，

7、也可以简化程序。初选铣刀半径为80，为了使切削连贯进给量应小于铣刀直径，选择为40，又因为粗加工加工精度为0.1即可，采用顺铣方式精度更好一些，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，所以主轴应输出较大扭矩，选用较低转速1500，切削速度都应该选择低速，故选择切入切出连接速度350，切削速度600。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

8、，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，切入切出连接速度800，切削速度1000，退刀速度100，如图20。图20扫描线精加工切削用量对话框下刀方式：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D10。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

9、择较高的切削速度，小的背吃刀量和进给量。进给量应小于铣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。求得刀具轨迹如图22。图22精加工刀具轨迹仿真加工模型如图23。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：(Gcode.cut,2012.5.23,16:53:29.500)N10G90G54G00Z100.000N12S1500M03N14X0.000Y0.000Z100.000N16X-1000.000Y-1120.000N18Z25.500N2
