《机械制图》是技工学校数控、机电专业学生必学的一门专业基础课,它介于基础课与专业课之间起着承上启下的作用,通过对该课程的学习,使学生能掌握正投影法图示空间物体的基本理论和方法以及由三视图绘制轴测图的基本方法。学习《机械制图》就是培养学生运用作图手段表达机械部件和零件的结构形状以及利用图解方法解决空间几何体的问题。在教学过程中教师要培养学生由物→图,再由图→物的思维过程,培养学生三维形状与相关位置的空间逻辑、形象思维能力,但学生要掌握这种技能,离不开空间想象力的培养。
Mechanical drawing is a professional basic course for students majoring in mechanical and electrical engineering in mechanic school. It plays the role of connecting between basic course and specialized course. Through the study of this course, students can master the orthographic projection method The basic theory and method of space object, and the basic method of drawing axonography from three views. Learning “mechanical drawing” is to train students to use the means of drawing to express the structure and shape of mechanical parts and parts, as well as the use of graphical methods to solve the problem of spatial geometry. In the process of teaching, teachers should cultivate the students from the object → map, and then from the figure → object thinking process, to cultivate the spatial logic and image thinking ability of the three-dimensional shape and relative position of students, but students need to master this skill without space imagination Strength training.
