| 在位计量检测以加工机床为硬件载体，实现加工、测量一体化，对提高产品质量和生产效率有重要意义。介绍了数控加工在位计量检测系统的组成与方案的实现过程，对系统的性能进行了现场试验，结果表明大型结构件数控加工在位计量检测系统可对大型数控加工零件工艺过程中的尺寸和形位误差进行准确在位测量，大大缩短了大型数控加工件的定位时间，有效提高了一次装夹加工的效率和合格率，避免了工件的二次装夹，降低了生产成本，为数字化装配提供有力保证。 |
| 英文摘要: |
| On-machine measurement and testing takes machine tool as hardware carrier to realize the integration of processing and measurement, which is of great significance to improve product quality and production efficiency. This paper introduces the composition and implementation process of the in-situ measurement and testing system for NC machining, and tests the performance of the system. The results show that the in-situ measurement and testing system for NC machining of large structural parts can realize the size and position errors in the process of large NC machining parts. Position measurement greatly shortens the positioning time of large NC parts, effectively improves the efficiency and qualified rate of one-time clamping, avoids the second clamping of workpieces, reduces the production cost, and provides a strong guarantee for digital assembly. |
