摘要 隨著科技的發(fā)展，硬脆材料在各個領(lǐng)域的應(yīng)用越來越廣泛。為了緊跟科學(xué)發(fā)展的形勢，在導(dǎo)師的帶領(lǐng)下進(jìn)行了以金字塔微結(jié)構(gòu)成型的評價模式研究為主題的試驗。 本論文以單晶硅材料做為試樣,磨削加工做出了微金字塔結(jié)構(gòu)，接著通過MATLAB 軟件處理其輪廓數(shù)據(jù)，對成形效果進(jìn)行分析。把實驗記錄的數(shù)據(jù)點通過合理的程序轉(zhuǎn)化為一個三維模型，清晰地展現(xiàn)微結(jié)構(gòu)表面形態(tài)；然后計算出最優(yōu)的擬合球半徑，用該球曲面展現(xiàn)金字塔頂部。這些將為微結(jié)構(gòu)功能表面加工精度評價有實際意義。 文中提出了在求球面半徑過程中發(fā)現(xiàn)的問題和現(xiàn)象，球擬合曲面的分析和評價，可作為后續(xù)深入研究，改善成形精度，改進(jìn)加工工藝的方向。 論文主要分為金字塔結(jié)構(gòu)的可視化與擬合球兩個部分，集中闡述了作者利用數(shù)據(jù)處理軟件MATLAB 將抽象的原始數(shù)據(jù)轉(zhuǎn)化為非常直觀的三維圖像的過程，并能夠利用算法求取與實際金字塔頂部曲面誤差最小的擬合球曲面，曲面擬合誤差最低達(dá)1.5um。 作者很好地利用了白光干涉的特點，通過程序擬合曲面的過程和得到的最佳效果，為微觀領(lǐng)域的觀測提供了一種思路。 關(guān)鍵詞：硬脆材料，金字塔結(jié)構(gòu)，磨削，評價方法
Abstract With the development of technology, hard and brittle materials were widely applied in all fields. In order to the scientific development of the situation is going, the professor led us to made a experiment what is for the evaluation model about pyramid structure of molding test theme. In this thesis, the sample is crystal silicon material, using it to made micro-pyramid structure, then we used the "MATLAB" software,to processed data, analysis of the forming effect. Recording data points put into the software and built a three-dimensional model, then it would clearly showing the microstructure morphology;Using of interpolation methods to dealing, showing the fitting spherical surface of the top of the pyramid, These will be of practical significance for the structure and function of the surface micro machining accuracy evaluation. This paper presents the problems and phenomena, found in the process for the solution with spherical radius; it can be as a follow-up in-depth study, to improve the forming precision, the direction of improved processing technology. Thesis is divided into two parts, the pyramid structure visualization and fitting the ball,it focused on the data processing. Author use the software of MATLAB to made the process about the abstract raw data transformation an intuitive three-dimensional image.And it can use algorithm to count the top surface and the actual pyramid, the smallest fitting error of the ball surface. Author was on the good use of white light interference characteristics, With the program obtained to fitting surface and the best resultsand.It’sprovided a new method of micro-field observation Keyword: Hard and brittle materials, the pyramid structure, grinding, evaluation methods
