摘要:	隨著科技的不斷進步和產品設計的日益複雜，曲面外觀的產品在現代工業中已逐漸成為高階產品的設計特色。然而，由於曲面造型的複雜性，傳統的弧規檢驗方法及CMM/OMM往往無法提供足夠準確的數據，導致產品品質控制面臨挑戰。為解決這問題，本研究引入3D掃描技術作為高精度、高效率的測量手段，並結合公差分析方法，以更精確地確定曲面外觀產品的合理公差範圍。本研究採用ATOS Q 3D掃描儀，利用其投影三角測量原理，快速獲取產品表面的三維數據。通過與傳統接觸式CMM及非接觸性 OMM技術的比較，驗證3D掃描技術在複雜曲面檢測上的可靠性和準確性。此外，本研究提出公差計算表，結合3D掃描數據和公差分析方法，充分考慮零件變形和配合要求，以確定合理的公差範圍。通過實驗驗證，證明該方法能夠有效提高產品品質的穩定性和可靠性。研究結果顯示，沖壓工件的外觀設計難以達到預定的輪廓度規格，而CNC工件的表現則更加穩定。這發現凸顯3D掃描技術在獲取產品幾何資訊方面的重要性，同時也強調在設計和製造過程中全面考慮製程限制的必要性。本研究為曲面外觀產品的品質控制提供新的思路和解決方案，有助於提高產品品質，降低生產成本，縮短產品開發週期。這項研究的啟示對於現代工業產品設計和製造具有重要的指導意義，為達到高品質、高效率的生產提供可行的途徑。;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.
