摘要
将CCD和光栅尺同时应用于布氏硬度压痕测量,试验证明:系统测量结果基本不受CCD对焦及照明光强变化的影响;测量准确度容易保证,重复性好,自动化程度及效率较高,同时大大缓解了布氏硬度测量中的视觉疲劳。
The CCD and grating ruler were applied to Brinell Hardness measurement in this paper.It was proved that the change of focus and illumination intensity of CCD have little influence on the hardness result.The measurement precision and repeatability were easily realized.As the hardness was measured more automatically and efficiently,the visual fatigue was alleviated.
