| Abstract: | In order to deepen students’ understanding of the modern cutting technology,and to understand the development trend of the modern cutting equipment,an experimental platform for the laser cutting of multi-degree-of-freedom dental hot-pressing model based on the binocular ranging principle is developed. This experimental platform combines the theoretical knowledge of mechanical design,mechanical electronics,computer image processing and other disciplines to extract the spatial coordinates of the gingival curve on the surface of the tooth hot pressing model. The laser cutting arm is controlled for cutting according to the cutting curve,which makes the cutting process more intuitive,deepens the students’ understanding the “Cutting principle and cutting tool” and “Modern manufacturing technology” courses,enhances their interest in the study of mechanical processing theory,and achieves good experimental teaching results. |
