Mechanical drawing, advanced mathematics, mechanical design, mechanical principle, interchangeability and technical measurement, fluid mechanics and pneumatic transmission, control engineering foundation, mechanical manufacturing technology foundation, mechanical engineering materials, electrical and electronic technology foundation, single chip microcomputer application and principle, machine tool electrical control and PLC and other knowledge.

Freshmen must learn mechanical drawing, which is the basis of learning mechanical knowledge, followed by advanced mathematics, interspersed with many disciplines such as science and engineering, and machinery is no exception.

Sophomore or junior, or even senior (because the course study and training plans of various universities are inconsistent), I began to study professional courses of mechanical specialty, including courses such as mechanical design and mechanical principle.

"Mechanical Design" and "Mechanical Principle", these two courses are specialized courses of mechanical specialty and the premise of learning mechanical knowledge. Other courses are supporting courses for mechanical specialty.

For example, interchangeability and technical measurement mainly focus on tolerance, which is one of the key parts in the process of mechanical design and drawing, while mechanical engineering materials mainly focus on the mechanical properties and metallographic structure of various materials, including how to choose various materials and so on.
