1、摘要针对大连机车厂现有的工艺，本文利用工业工程相关理论对整个车轮工艺程序、流程以及布置径路进行了分析，并提出了相应的改进措施，为将来大连机车厂将要建设新的厂区提供设计参考。（1）运用程序分析的方法，对大连机车厂车轮加工进行了工艺程序分析，绘出了改进前后工艺程序，对比说明了改进后提高了加工效率。（2）运用流程程序分析以及布置和经路分析理论，从工艺流程以及布置和经路等方面对大连机车厂机五车间进行了改进，缩短了搬运时间，提高了效率。（3）通过改进钻床的定位系统取消了划线定位打冲眼的加工步骤，节省了一道工序。通过改进检验设备来将磁粉探伤和超声波探伤工序合并达到优化的目的。将辐板

2、孔倒角加工设备移动到钻辐板孔设备附近来减少搬运距离。将精车一加工设备移动到大门附近，把精车二加工设备移动到磁粉探伤仪对面，这样既减少了搬运距离又解决了路线交叉问题。通过改变半成品暂存位置来进一步减少搬运距离。关键词：程序分析流程程序分析工艺程序分析ABSTRACTFortheexistingtechnologyofDalianLocomotivePlant,weusedthetheoryofindustrialengineeringtechnologyprogramtoanalyzetheentirewheel,processandpathlayout,andpropo
