| dc.description.abstract | In today′s rapidly advancing technological landscape and increasingly intricate
product designs, curved appearance products play a pivotal role in modern industry.
However, the complexity of curved shapes poses challenges for traditional profile
gauge inspection methods, often resulting in inaccurate data and difficulties in product
quality control. To tackle this issue, this study introduces 3D scanning technology as a
precise and efficient measurement approach, coupled with tolerance analysis methods,
to accurately determine reasonable tolerance ranges for curved appearance products.
Utilizing the advanced ATOS Q 3D scanner, this research employs its projected
triangle measurement principle to swiftly capture three-dimensional data of product
surfaces. By comparing it with traditional contact-based CMM/OMM technology, the
reliability and accuracy of 3D scanning technology in complex surface inspection are
validated. Additionally, an innovative tolerance calculation table is proposed,
integrating 3D scanning data and tolerance analysis methods, to determine reasonable
tolerance ranges while fully considering part deformation and assembly requirements.
Experimental validation demonstrates that this method effectively enhances product
quality stability and reliability.
The study findings reveal that while the appearance design of stamped parts may
struggle to meet predetermined contour specifications, CNC parts exhibit more stable
performance. This underscores the importance of 3D scanning technology in obtaining
product geometric information and underscores the necessity of comprehensive
consideration of process limitations in design and manufacturing. The research
provides novel insights and solutions for quality control of curved appearance products,
contributing to improved product quality, reduced production costs, and accelerated
product development cycles. The implications of this study are significant for modern
industrial product design and manufacturing, offering a viable approach to achieve
high-quality and efficient production. | en_US |
