基于分类逻辑的制图法探析

Drawing Method Based on Classification Logic and Analysis

在高等教育的机械类专业中,培养出的学生机械制图实践能力较差,往往存在不能满足就业岗位实际工程制图能力需要的问题。这种情况也常出现在企业中的初级技术人员身上,为此,可从多年的生产实践和教学实践经验出发,结合具体工程的零件和装配图的绘制情况,提出了一种基于特征(零件)分类逻辑的制图思路。在零件/装配体的机械制图中,应基于特征分类逻辑按8个信息步骤来完成零件的逻辑工程制图,应基于零件种类分类逻辑按7个信息步骤来完成装配体的逻辑工程制图。

The mechanical students in higher education are usually weak in mechanical drawing practice and thus not qualified for the related posts.The same is true among junior technicians.The paper,based on actual practices and teaching experiences,puts forward a new mechanical drawing pattern on view of the features and categorization of the parts.In mechanical drawing concerning assembly and parts,eight steps are to be followed according to the sorting logic about the features of the parts and seven steps to be followed according to the sorting logic about the categorization of the parts.
