盘零件的数控加工及编程设计 摘要 随着科学技术的进步，现代机械产品日趋精密复杂，改型换代频繁，发展现代数控机床是当前机械制造业技术改造、技术更新的必由之路。数控机床当中数控车床应用比较广泛,该设计内容是对数控铣床简单了解。 本文主要讲述盘零件的加工工艺，通过Master CAM X5画出三维图，对零件图的工艺性分析、加工刀具的选择。然后用?12mm的立铣刀粗铣?160h9外圆及?4mm的立铣刀精铣?160h9外圆，用可调式镗刀分别镗?70H7孔及镗6-?80H7孔，再用?6mm的点钻打螺纹底孔，用?15mm的麻花钻钻底孔,用M16丝锥加工螺纹。最后导出程序。 关键词：工艺分析、装夹方案、工艺流程、三维造型、自动编程 Abstract With the progress of scie
