直軸非球面鏡面加工系統及方法 Straight axis aspheric mirror processing system and method

本發明涉及一種超精密加工系統及方法，特別涉及一種直軸非球面鏡面加工系統及方法。 The invention relates to an ultra-precision machining system and method, in particular to a direct-axis aspheric mirror processing system and method.

隨著科技的進步，超精密加工儀器亦不斷創新。工廠雖已經有了精密及自動化機械，也需要相對應的加工儀器以及正確的加工技術，高精度的產品製造才能達成。 With the advancement of technology, ultra-precision processing instruments are constantly innovating. Although the factory already has precision and automated machinery, it also needs corresponding processing equipment and correct processing technology, and high-precision product manufacturing can be achieved.

非球面光學零件係一種非常重要的光學零件，常用的有抛物面鏡、雙曲面鏡、橢球面鏡等。非球面光學零件可以獲得球面光學零件無可比擬的良好的成像品質，在光學系統中能夠很好的矯正多種像差，改善成像品質，提高系統鑑別能力，它能以一個或幾個非球面零件代替多個球面零件，從而簡化儀器結構，降低成本並有效的減輕儀器重量。 Aspherical optical parts are a very important optical part. Commonly used are parabolic mirrors, hyperbolic mirrors, ellipsoidal mirrors, etc. Aspherical optical components provide unparalleled imaging quality for spherical optical components. They can correct a variety of aberrations, improve imaging quality, and improve system identification in optical systems. It can be used with one or several aspherical parts. It replaces multiple spherical parts, simplifying the instrument structure, reducing costs and reducing instrument weight.

近些年來，出現了許多種新的非球面超精密加工技術，主要有：電腦數控單點金剛石車削技術、電腦數控磨削技術、電腦數控離子束成形技術、電腦數控超精密拋光技術和非球面複印技術等，這些加工方法，基本上解決了各種非球面鏡加工中所存在的問題。前四種方法運用了數控技術，均具有加 工精度較高，效率高等特點，適於批量生產。 In recent years, there have been many new types of aspheric ultra-precision machining technologies, including: CNC single-point diamond turning technology, computer numerical control grinding technology, computer numerical control ion beam forming technology, computer numerical control ultra-precision polishing technology and aspheric surface. Copying techniques, etc., these processing methods basically solve the problems in the processing of various aspherical mirrors. The first four methods use numerical control technology, both of which have High precision and high efficiency, suitable for mass production.

目前，超精密加工係指加工精度為1~0.1μm，表面粗糙度為Ra0.1~0.01μm的加工技術，但這個界限是隨著加工技術的進步不斷變化的，今天的超精密加工可能就是明天的一般加工。超精密加工所要解決的問題，一係加工精度，包括形位公差、尺寸精度及表面狀況，有時有無表面缺陷也是這一問題的核心；二係加工效率，有些加工可以取得較好的加工精度，卻難以取得高的加工效率。超精密加工應該包括微細加工和超微細加工、光整加工等加工技術。 At present, ultra-precision machining refers to processing technology with a processing precision of 1~0.1μm and a surface roughness of Ra0.1~0.01μm, but this limit is constantly changing with the advancement of processing technology. Today's ultra-precision machining may be General processing tomorrow. The problems to be solved by ultra-precision machining, one-line machining accuracy, including geometrical tolerance, dimensional accuracy and surface condition, sometimes with or without surface defects is also the core of this problem; second-line processing efficiency, some machining can achieve better machining accuracy However, it is difficult to achieve high processing efficiency.
