Abstract：

Dimension measuring is a crucial part in heavy forging processing. In the process of forging and machining, accurate measurement of heavy forging is of great significance for improving quality and efficiency and reducing material machining allowance. Traditional contact measurement technology cannot be satisfied with the requirement of current industry. Non-contact measurement technology has been developed rapidly due to its characteristics of fast and accuracy. The mechanical measurement, the measurement by laser, the vision measurement by CCD and structured light were reviewed. The advantages, disadvantages and applications of each method were analyzed. A new method by linear structured light and CCD camera scan was presented. At last, the current situation of on-line dimension measurement of heavy forging was summarized.
