结合制图知识的刀具角度教学

Teaching of tool angle with combination of drawing knowledge

刀具角度是教学中的重点和难点。结合机械制图相关知识,以车刀为例,用机械制图知识讲解刀具角度,将抽象的空间概念具体化,帮助学员理解和掌握,从而提高教学效果。

Tool angle is the key and difficult point in teaching. Taking lathe tool as an example of teaching,tool angle is taught by using mechanical drawing knowledge. The teaching can concretize abstract space concepts so that it is easier for students to understand and master. The teaching effect is thus improved.
