摘要

在不斷要求高精度且自動化的製造業中，鏟花技術扮演著重要的角色，鏟配技術可以提升工具機組裝精度。目前雖然有電動鏟花刀增加鏟花速度，但是仍然改變不了依靠人工進行鏟花作業的方式，本研究擬針對鏟花技術進行探討及設計一利用機構動作來代替人工鏟花。
本研究設計一複合式鏟花機構，該機構可以利用粗鏟及精鏟兩種不同方式完成精密鏟花。本文透過CATIA建構實體模型，並進行組件分析，接著再使用機構對鑄鐵及貼有耐磨片之工件進行鏟花測試，最後使用鏟配量測系統對工件分析鏟花參數，驗證本機構是否能達到目標參數。本機構X、Z軸行程為20 mm，定位誤差為0.9 μm，機構重量15 kg，進刀速度480刀/分。

In the machine tool industry, high precision and automation are required for manufacturing and assembly processes. Scraping is basic and key technique in high-precision machine tools. The accumulated tolerance from a machine tool is eliminated by scraping. In general, the traditional scraping process is time-consuming and tedious manual labor. To overcome these shortcomings, a novel a composite scraping mechanism that comprises a simulation mechanism and reciprocating mechanism is developed and designed. The composite scraping mechanism can perform two scraping functions: precision scraping and rough scraping.
The model of composite scraping mechanism is simulated and Analyzed by CATIA. Cast iron and Turcite work pieces can be scraping tests. Then, the scraping work pieces can be measured by scraping measurement. The parameters of the scraping work piece can be evaluated. The strokes of X-axis and Z-axis for composite scraping mechanism are 20mm.The positioning error of composite scraping mechanism is 0.9μm. The weight of composite scraping mechanism is 15 kg. The automatic scraping mechanism can reduce the time of operations and the difference of removal depth for every scraping processing.
