【摘 要】：
拨叉行业是我们通用机械重要分支，无论是在工业还农业中
，只要有流体管道的地方,阀门的作用都是巨大的，而随着时代
的发展，拨叉的类型也发展的越来越全面，制造拨叉的技术也越
来越先进。本文一例拨叉零件数控车床加工的程序编制与步骤，
加工工艺的选择问题进行探讨。进行整套的工艺分析与计算，按
工艺程序卡进行编程与加工。
【关键词】：拨叉 数控加工 工艺 数控铣床

Dials forks the profession is our general machinery
important branch,regardless of is in the industry also
agriculture, so long as has thefluid pipeline the place,
the valve function all is huge, but alongwith the time
development, dials the type which forks also to
