Description

technical field

[0001] The invention relates to the technical field of teaching aids, in particular to a turning tool teaching aid which can be flexibly disassembled and combined. Background technique

[0002] The geometrical angle of cutting tool is the key and difficult point of learning for students majoring in metal cutting. In the lecture, the teacher mainly takes the turning tool as an example to explain. The explanation includes more than ten definitions including the geometric elements of the cutting part of the tool, the reference coordinate plane of the tool, and the geometric angle of the cutting part of the tool. The concept of space is strong and the content is obscure and abstract. Therefore, the teacher must When explaining, it is only with the help of appropriate teaching models that students can master and understand this part of the content. The model used in the current teaching is often a large-sized turning tool teaching model. This model can only refle...
