【摘要】：非光滑表面是指在界面粘附系統(tǒng)中,若一個光滑表面內的任何宏觀區(qū)塊上存在一個或幾種因素構成的非光滑效應,則該表面為非光滑表面。這種結構在各個領域表現出的特殊功能,成為國內外學者和工程界研究的熱點。在機械摩擦磨損過程中,非光滑表面具有減少摩擦、降低能量消耗等功效。非光滑表面的常用加工方法有激光加工、磨料噴射加工、電火花加工、切削、滾壓、磨削、電化學腐蝕加工等。而將磨削技術應用在非光滑表面加工是一個嶄新的領域。目前,非光滑表面的磨削加工方法生產效率低、加工成本高、磨削表面質量不易控制。因此,提高非光滑表面磨削性能已成為新的研究方向。為此,利用金剛石筆將砂輪修整成螺旋槽表面,通過選擇合理的磨削參數,探求非光滑表面形貌的成型規(guī)律,對磨削非光滑表面的理論及實際應用具有重要意義。首先,利用金剛石筆將砂輪修整成螺旋槽表面,探討車削法修整砂輪技術,分析各個參數對砂輪修整過程的影響。其次,在確定車削修整砂輪基礎上,建立螺旋槽砂輪表面的數學模型,分析金剛石筆刀具參數和加工參數對砂輪螺旋槽的影響,設計出單、雙螺旋槽砂輪。再次,建立單顆磨粒外圓磨削運動軌跡的數學模型,結合螺旋槽砂輪數學模型分析了磨削參數對單、雙螺旋槽砂輪磨削工件非光滑表面形貌特征的影響。最后,在MATLAB仿真平臺中,研究螺旋槽砂輪表面幾何參數及磨削參數對工件非光滑表面形貌的影響規(guī)律�；诤侠淼哪ハ鲄�,獲得一定規(guī)律排布的非光滑表面形貌。
[Abstract]:Non-smooth surface is a non-smooth surface if there is a non-smooth effect of one or more factors on any macroscopic block of a smooth surface in the interfacial adhesion system. The special function of this kind of structure in various fields has become the research hotspot of domestic and foreign scholars and engineering circles. In the process of mechanical friction and wear, the non-smooth surface can reduce friction and energy consumption. The common processing methods of non-smooth surface are laser machining, abrasive injection machining, EDM, cutting, rolling, grinding, electrochemical corrosion processing and so on. The application of grinding technology in non-smooth surface processing is a new field. At present, the non-smooth surface grinding method has low production efficiency, high processing cost and difficult to control the grinding surface quality. Therefore, improving the grinding performance of non-smooth surface has become a new research direction. Therefore, the diamond pen is used to repair the grinding wheel into a spiral groove surface, and by selecting reasonable grinding parameters, the shaping law of the non-smooth surface morphology is explored, which is of great significance to the theory and practical application of grinding the non-smooth surface. Firstly, the grinding wheel is trimmed into a spiral groove surface by diamond pen, and the grinding wheel dressing technology by turning method is discussed, and the influence of each parameter on the grinding wheel dressing process is analyzed. Secondly, on the basis of determining the turning and dressing wheel, the mathematical model of the surface of the spiral groove grinding wheel is established, and the influence of the diamond pen tool parameters and machining parameters on the grinding wheel spiral groove is analyzed, and the single and double spiral groove grinding wheels are designed. Thirdly, the mathematical model of the motion track of single abrasive cylindrical grinding is established, and the influence of grinding parameters on the non-smooth surface morphology of workpiece grinding with single and double spiral groove grinding wheel is analyzed in combination with the mathematical model of spiral groove grinding wheel. Finally, the influence of surface geometric parameters and grinding parameters of spiral groove grinding wheel on the non-smooth surface morphology of the workpiece is studied in the MATLAB simulation platform. Based on the reasonable grinding parameters, the non-smooth surface topography is obtained.
