【摘要】 文章以成果为导向，以“设计加工减速器”为教学改革案例，学生分组对轴或齿轮进行减速器零部件三维绘制、3D实物打印以及最后的组装，最终通过学生在人群中位置变化，实现增值评价。让学生加工设计能力得到锻炼，对精益求精的大国工匠精神以及职业道德精神也有更深刻的理解。更多还原

【Abstract】 This paper is result-oriented and takes "Designing and Machining Reducer" as a teaching reform case.Students in groups carry out 3D rendering,3D physical printing and final assembly of shaft or gear reducer parts.Finally,through the change of students’ position in the crowd,value-added evaluation is realized.Let the students’ processing and design ability be trained,and have a deeper understanding of the spirit of excellence and professional ethics.更多还原
