摘要

本論文於傳統鏟花作業中觀察與研究後，找出了可以提升鏟削效率與減少毛邊的方法，並利用電腦繪圖軟體，先實體建模設計出方型、三角型、半月型及千鳥型鏟花刀，再加以實際製作，最後選擇合適之氣動裝置與設計之鏟花刀結合。經試鏟後，此鏟削方式可輕易鏟出鏟削常用之四種油袋，針對各式綜合加工機鏟削後也明顯比傳統鏟花提升效率許多，鏟削時所產生之毛邊也比傳統鏟花減少。有效的讓鏟花師傅鏟配效率提升，省時省力，品質也能維持一定，裝配簡單成本低，對於鏟花作業又是一大貢獻。

A method to improve scraping efficiency and reduceresidual burrs was identified in this thesis by observation and study of traditional scraping. Computer-aided drawing program was introduced to establish the physical models of square, triangular, crescent-shaped and chidori-shaped (千鳥型) scrapers before these scrapers were actually made. Finally, suitable pneumatic device was selected to be combined with the designed scrapers. A series of scraping trials showed that the four types of oil pocket commonly seen and made were easily produced by using this scraping technique. The scraping efficiency was also significantly improved on several types of conventional machining center. The burrs generated from scraping were much fewer than those generated from conventional scraping. The work efficiency of scraping technicians was improved effectively, and the new technique helped people by saving time and energy while the quality of products was maintained at a stable level. The new scrapers are easy to install and cost less expense, which is a great contribution to scraping.
