1、三坐標測量（接觸型測量零件的設計班級：0781053學生：指導老師：摘要：隨著 CAD/CAM泉加工及快速成型等先進制造技術的不斷發展，以及這些技術在機械行業中的普及應用，機械設計與制造領域正發生著一場深刻的技術，傳統的二維設計及模擬量加工方式正逐步被基于產品三維數字化定義的數字化制造方式所取代。在這場技術中，逐步掌握三維 CAD/CAM的使用，并用于數字化的設計與制造是其中的關鍵。三坐標測量機(CMM)則是一種高效率、高精度、多功能的檢測設備。七十年代以來在測量機上廣泛應用電子計算機后，它的性能和自動化程度都大為提高,使用范圍也更廣泛。昔日三坐標測量機主要面向航空航天等高技術產業，而今日，它

2、在現代制造業的各個領域中都得到了廣泛的應用，已成為機械制造業中發展最快的現代量儀之一。本文就是采用 UG 三維建模設計出基于三坐標測量技術能夠進量的實體。然后把實體導入到 AutoCAD 繪圖，得到實體零件圖。所設計出來的實體的曲面圖形部分還要在微機上進行 CAM 仿真加工并通過后處理得到 NC程序。然后利用三坐標測量機對現有類似零件進行檢測。這樣不僅能夠較好的掌握 UG 的三維建模方法，AutoCAD 的繪圖方式，還能熟悉三坐標測量機的操作環境。：三坐標測量技術實體設計UG指導老師簽名：The design of typical measurement component which bas
