几何公差标注的教学技巧研究

Research on Geometrical Tolerancing Label Teaching Skill

几何公差的标注是《互换性与技术测量》课程中的重要组成部分,是教学中的重点和难点。文章分析了几何公差标注的特点,对几何公差标注在教学中易出现的问题进行了详细解析,进而提出了"3-Question"式的解决方法,经教学实践验证,此方法对于学生掌握正确标注几何公差具有显著的提升效果。

As a very important component of Interchangeability and Technology-based Measurement course, labeling the Geometrical Tolerancing is always a key and difficult point. A thorough analysis was made on the characteristic and difficult point, and also the problem during teaching the Geometrical Tolerancing label, then a 3-question solution was raised. This solution was validated through the teaching practice, can significantly help students to learn to label the Geometrical Tolerancing correctly.
