大型汽轮发电机转轴加工人因防错程序开发与应用

Development and Application of Human Error Prevention Program for the Processing of Large Turbine Generator Shafts

转轴作为汽轮发电机的核心部件,具有工作转速高、运行工况复杂、转轴锻件价值高、不可修复等特点,因此要求转轴加工必须做到一次性成功。根据人因预防管理理论开发的“人因防错模块”数控程序具备转轴铣槽分度防错、铣槽深度防错、刀具参数防错、加工流程固化等功能,可以很好地实现转轴铣序加工过程防错,能有效地防止转轴的铣伤和报废。数控转子铣机床“人因防错模块”数控程序不仅让产品实现质量零缺陷目标更近了一步,而且“人因防错模块”数控程序开发成本低,具有一定经济效益,可以在数控加工机床进行推广使用。

As the core part of the turbo-generator,the rotating shaft has the characteristics of high working speed,complicated operating conditions,high value of forging shaft,and unrepairability.Therefore,the manufacturing of the shaft must be successful at one time.The"Human Factor Error Prevention Module"NC program based on the human factor prevention management theory has functions such as groove-milling dividing error prevention,groove-milling depth error prevention,tool parameter error prevention and machining process solidification,etc.These functions can effectively prevent the milling damage and scraping of the rotating shaft.The NC program of the"Human Error Prevention Module"for CNC rotor milling machine not only brings the product closer to the goal of zero quality defects,but also the low cost of the NC program for the"Human Error Prevention Module"has certain economic benefits.The program can be popularized in all CNC machine tools.
