利用三坐标测量的发射装置装配工序能力分析

The process capability analysis for launcher assembly operation based on the coordinate measuring

三坐标测量机已经广泛应用于机械加工生产现场,其在提高检测效率、保证质量和过程控制等方面发挥着重要作用。发射装置具有多型号、多批次和多批量的特点,除了零件尺寸,装配中也有很多关键尺寸需要测量。举例说明如何使用三坐标测量机测量装配尺寸,评价发射装置装配生产过程能力,该方法对解决装配生产中的过程稳态失衡问题,提高装配工序能力,具有一定的意义。

The CMM has been widely used in the mechanical processing production field,which plays an important role in improving test efficiency,assuring quality,and process control.The launcher is characteristic of products＇ variety,big product batch,and various volumes.Besides the parts,there are many key dimensions of the assembly components.Application of the CMM to measure assembly dimension and analyze the assembly process capability of launcher is introduced through typical cases.It is valuable for preventing the imbalance process and improving the assembly process capability.
