First of all, mechanical design engineer is just a general term, including many categories, such as product design, tooling design, product structure design, as well as fine interior and exterior decoration, body, upper and lower parts, etc., so you need to determine the direction first. Mechanical design is not a clear direction and should continue to be refined. Otherwise, you will be confused, don't know what to do in the end, or know nothing after learning.

One: Foundation

The introduction must be mechanical drawing. As a designer, you must know painting very well. Mechanical drawing is also an introductory course for mechanical design majors. Among them, there are many views that are most used, such as the third angle method, gear transmission, fit clearance and so on. I think it is irrational to eat this book directly when I study by myself, because it is boring. Therefore, I suggest you buy an introductory book on the basis of mechanical drawing, the content of which is as detailed as possible, and it will be used as a database for real-time search in the next study, which will greatly increase efficiency.

Second: processing technology

Although mechanical design does not need the hands-on ability of car model drilling and planing, it needs to know everything from design drawings to finished products. If you don't understand the processing of products? Technology, then the products you design may not meet the production requirements, so before learning mechanical design technology, you must know something about mechanical processing technology.

Three: Software

When designing, we inevitably need to make 2D and 3D drawings, so we need to learn drawing software. CAD is widely used to make 2D drawings, but you can also make them directly with 3D software. 3D software will be biased in various industries. CRO-E, UG and CATIA are basically used in product design, UG and CRO are more commonly used in small products, and CATIA is basically used in aviation pages of large products such as automobiles and airplanes, but UG is basically used in the design of the bottom production mold, and the overlord of sheet metal is SW. Therefore, we can refer to the above analysis to learn which modeling software, but 3d software is interlocking, so it takes a lot of time and cost to master one.

The above three aspects belong to the foundation, no matter which branch of mechanical design industry you are engaged in, you need to master the basic knowledge.

Four: direction

According to your hobbies, or the direction you are good at, rather than involving a little in every field, although mechanical design is interlinked in many sub-fields, each field has its profound part, so it is possible to become a master in a field, and the mechanical industry is very experienced. Don't expect two or three years of experience to be awesome. It may be ok in other industries, but in the machinery industry, this is just the beginning and there is still a long way to go.

In addition, self-study requires strong self-discipline. If you don't have good perseverance, you will get started, let alone learn. There are thousands of people who want to learn by themselves, and few people can achieve their goals through self-study, so you should evaluate whether you can keep learning and set a feasible goal.
