项目摘要

The free surface qualities of the material change accompanied with a plastic deformation level. It has been investigated for a long time that the surface roughness of the material increases with an increasing strain. The control of the surface roughness of product before pressing the thin plate and plating the cold rolled sheet is a serous problem. Therefore, it is necessary that the surface roughness is quantitatively measured with high accuracy. Generally, the methods for measurement of the surface roughness are to measure the profile of the surface by using the profile meter and to measure the brightness by using the reflection meter. In the former method, it is difficult to measure the two dimensional surface roughness in operation, and in the latter method, it is possible to measure the mean surface roughness nondestructively, but the values can not be measured with accuracy. Consequently, the two dimensional surface roughness can not be measured in operation with high accuracy by … More these methods. A new method for measurement of the surface roughness has been developed by means of a laser beam by the authors. If the laser beam with a high coherency is thrown on the rough surface of metals, the laser beam is diffracted by the surface structure of the metal and the characteristic intensity distribution is observed. The observed distribution is obtained by Fourier transform of the distribution of the beam wave. Since the surface profile of the metal is connected with the distribution of the beam wave, the intensity distribution includes the qualities of the surface profile. Therefore, the surface profile can be examined by measuring the intensity distribution. It is possible to measure the surface roughness nondestructively without touching the material by this method. Since this method can be used in operation, the application of this method to the control of the product surface expected. In this paper, a inline apparatus for measurement of surface quality is developed newly. Less
材料的自由表面质量随塑性变形水平的变化而变化。长期以来,人们一直在研究材料的表面粗糙度随应变的增加而增加。薄板压制和冷轧板电镀前产品表面粗糙度的控制是一个严重的问题。因此,有必要对表面粗糙度进行高精度的定量测量。通常,测量表面粗糙度的方法是用轮廓计测量表面的轮廓,用反射计测量表面的亮度。前一种方法在操作中难以测量二维表面粗糙度,后一种方法可以无损测量平均表面粗糙度,但不能准确测量。因此,在实际操作中,用这些方法无法高精度地测量二维表面粗糙度。本文提出了一种用激光束测量表面粗糙度的新方法。将高相干激光束投射到金属的粗糙表面,激光束被金属表面结构衍射,观察到特征光强分布。对光束波的分布进行傅里叶变换,得到了观测到的分布。由于金属的表面轮廓与光束波的分布有关,因此强度分布包括表面轮廓的质量。因此,可以通过测量强度分布来检测表面轮廓。用这种方法可以在不接触材料的情况下无损地测量表面粗糙度。由于该方法可以在操作中使用,因此应用该方法对产品表面的控制是预期的。本文研制了一种新的表面质量在线测量装置。少
