中文摘要

鏟花技術視為精密工具機能有基本準確度的起點,依據工具機的「母性原理」,原工具機加工出來的工件精度不會超過該工具機之精度,然而這些工件所組裝的工具機再加工出的工件,其精度會有世代累積的誤差,目前工具機的發展史已有200年了,卻沒有出現這種世代誤差,全歸巧鞳u鏟花技術」。鏟花技術都還是處於人工的階段,費時且費力,是一道相當繁複的過程,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。
本文的研究目標主要為設計一迴轉式自動鏟花機構,針對國內外鏟花技術的文獻和專利做搜尋以及整理,做為鏟花技術要求的資料庫建立。對於目前人工鏟花進行探討,分析如何以人工力道改用機構自動鏟花,透過電腦繪圖軟體建構實體模型,再匯入有限元素分析軟體「VisualNastran」做動態模擬測試,並將模擬後的參數設定,做為加工零件的依據,最後組裝工件後實際做鏟花測試,調整出最佳化參數。並量測鏟花試片後,與鏟花師父所刮削之工件做對照,成左漸擖X手工鏟花之刮痕,也能達到足夠的深度以供含油用。本研究可節省人力與時間,而且成本低廉、裝配簡單、控制簡易對於鏟花技術做進一步之貢獻。

英文摘要

The scrap technology is considered as the fundamental of the accuracy of precision machine tools. According to the maternal principle, the accuracy of components which were fabricated by a machine tool is lower than that of the machine itself. The products of a machine, which was assembled by using the products of the first generation of machine, will have the accumulated tolerance. Up to now, the history of the development of machine tools is over 200 years, the accumulated tolerance was not obvious. The scarp technology plays an important role. So far the carp technology was operated manually and the procedure is very complicate and time consuming. In this paper, a mechanism is designed to replace the manually carping.
A rotary type automatic scraping mechanism is presented in this research. Papers and patents are surveyed and analyzed firstly. Several trips to visit experienced scrapping master are also arranged. The PRO ENGINEERING software is used to build the solid modeling of a scrapping mechanism. The motion programming, dynamic simulation, and scrapping force analysis are carried out by using the finite element analysis package VISUAL NASTRAN. After several modifications a final design of a rotary type scrapping mechanism is set and fabricated. After testing and adjusting, the best operating parameters of the scrapping mechanism are obtained. The scarping sample is compared with the one which was made manually. The depth of the scratch is deep enough to hold the oil. The rotary type automatic scraping mechanism presented in this study is with many advantages, such as more efficient, low cost, simple assembling and easy control. It is believed that this study is helpful for the automation of scrap technology.
