Abstract
During the production of the low-pressure casting aluminumwheel hub, the head face deformation and axial deformation of the casting blank are always happened due to various factors.The casting wheels beyond tolerance are considered as waste products with no need for further machining. Traditionally, the measurement of the deformation is usually static and by handwork,which limits the accuracy and reliability. This paper introduces anon-line automatic measuring system for casting wheels based on laser measuring technology. The configuration of the system and measuring method are presented in detail. Test results showed that the system could meet the measurement requirements: the whole measurement process operated quickly with the total time of 30s; the dimensional accuracy reached 0.02mm while the measurement error of the deformation was within 0.04mm. The system achieves better repeatability and reliability compared to the manual measurement.
