dc.description.abstract航太葉片在功能性與安全性的需求下,在加工上具有相當嚴謹的品質要求,傳統上使用一維、二維量具與樣版規作為葉片檢測的工具,然而隨著三次元量測與軟體技術的普及,應用三次元量測以作為產品最終檢驗已是國外航太大廠的趨勢,因此,本研究乃是配合國內某航太廠之需求,發展風扇葉片與噴嘴另件機製尺寸之三次元檢測技術。 在風扇葉片方面,研究的重點著重於翼型面之三次元量測技術發展與量測資料分析。翼型面之檢測需要葉片藍圖與3D CAD模型兩項資料,藍圖提供擬檢測之所有尺寸與幾何公差之相關資訊,3D CAD模型則提供三次元量測規劃與量測資料分析時使用。本研究針對風扇葉片翼型面之檢測需求發展一完整的流程,主要發展的項目包括風扇葉片座標系統建立、翼型面等高度量測方法、葉片輪廓曲線量測方法、翼型面參數分析、輪廓公差分析等。所發展的技術已實際應用於該航太廠之葉片生產,並已獲得國外原廠對於檢測結果之認可。 在噴嘴另件之檢測方面,著重於座標系統之建立與自動化機製尺寸檢測程式之發展。噴嘴另件之座標系統建構方法使用六點定座標的方法,此一方法是許多葉片藍圖設定座標系統使用的方法,本研究發展一座標疊代的方法以設定三次元量測之座標系統。在自動化機製尺寸檢測程式發展方面,針對藍圖指定之數十項尺寸與幾何公差,發展自動化之量測及尺寸和幾何公差分析功能,該程式可在三十分鐘內完成噴嘴另件所有機製尺寸之檢測,明顯地比人工量測更迅速。zh_TW
dc.description.abstractThe need in functionality and safety for blades in airplanes has made the quality control of the manufacturing of the blades to be an important work. One-dimensional gages, two-dimensional gages and templates are traditionally used for the inspection of blades. However, three-dimensional inspection is getting popular in some major aerospace industrial Companies as the coordinate measuring machines incorporating software technology has become matured. The purpose of this study is to develop three-dimensional inspection technology for fan blades and nozzle segments, which are manufactured by one of the aerospace industrial Companies. The study in fan blades is focused on the development of coordinate measuring metrology for airfoil and the analysis of the measured data. It requires the blueprint and the 3D CAD model as the input, where the blueprint is used to obtain the information required for measurement and the 3D CAD model is used for measurement planning and data analysis purpose. This study develops an integrated procedure for the inspection of fan blades, including coordinate system setup, constant height measurement method for the airfoil, blade profile measurement, airfoil parameter analysis and profile tolerance analysis. The proposed technology has been applied to the manufacturing of a type of fan blade. The analysis results have also been verified. The study in nozzle segment is focused on the coordinate system setup and the development of a program for automatic inspection of the machining dimensions. The coordinate setup method is based on so-called six-points coordinate setup method, which is widely used in blade blueprints. This study develops an iterative method for the setup of the coordinate system on the coordinate measuring machine. The automatic measurement procedure is developed based on the dimensions specified by the blueprint. The program can measure all the machining dimensions of a nozzle segment within thirty minutes, which is obviously faster than manual operations.en_US
