Understand the knowledge system, and then cooperate with the following classification of mechanical engineers to see where you are-
First of all, don't think that machinery is only for structure, let alone that structure is only using PROE, solidworks or other software ...
In fact, those who engage in mechanical institutions have an innate advantage, that is, all products are based on structure, and it is possible for you to develop anywhere. Doing structure can make you have a more intuitive understanding of products and make you more rigorous and practical. On the other hand, it is a long and painful exercise process to engage in structure, but once you practice your skills, you are not afraid of getting old, and even the older you get, the more popular you are.
What are the stages of advanced mechanical engineer?
Rookie level
1. Rookie Level 1
Can use AUTOCAD to draw some simple two-dimensional drawings, according to which you can imagine the three-dimensional shape of the product.
2. Rookie Level 2
You can see the tolerance, materials, surface treatment, technical requirements and other information on your two-dimensional drawing. And you marked the information yourself, and you know what they mean.
3. rookie level 3
You can draw two-dimensional drawings, and the drawings you draw really seem to be able to be processed into real objects, although sometimes you make some mistakes, for example, even Germans can't make them with high accuracy, not to mention Master Zhang in your workshop. At the request of the leader, you can use some three-dimensional software to draw an effect diagram, although it is of no practical value, at least it is very fulfilling.
Entry level
1. Entry Level 1
You already know how your products are processed, and you know the significance of each process. If improvement is needed, you can generally judge where to start, and you can guess a thing or two about the possible impact after improvement.
At this time, you have deeply realized that two-dimensional engineering drawings are far more meaningful than three-dimensional models. You begin to despise so-called mechanical engineers who can only build some 3D models with 3D software.
2. Entry Level 2
You begin to understand what enterprise informatization means. Knowing that three-dimensional design is actually very useful, and you can integrate the process information you love into three-dimensional design. At this time, you should have been able to skillfully design some commonly used parts by using 3D software, and generate 2D engineering drawings that can guide production, or directly take them to CNC equipment for processing.
Expert level
1. Expert Level 1
You have been able to use related design software to manage production, including drawing design and BOM)； management. You are already very clear about the production process, and you can identify key technical points and focus on solving them; Even have begun to try to use finite element analysis for strength, fatigue and other analysis, and can easily write an eloquent design document, it is not a problem to fool the novice. And if you haven't become a design director, you may need to work harder in interpersonal relationships.
2. Expert Level 2
You have vaguely felt that it is a waste of your time to simply and repeatedly design drawings, because you already know these things by heart. You'd like to spend more time on improving the competitiveness of the whole product, such as how to reduce the cost, how to improve the technological process and how to improve the design efficiency.
You can see that there are still some deficiencies in the structure, materials and functions of your products. You can realize that this is not something you can change alone. You start to make systematic consideration by using the surrounding technical resources, make plans to improve the competitiveness of your products, and list the technical nodes to break through one by one.
3. Expert level 3
By this time, you have gone beyond the scope of "structural design". You should know very well that your product has no potential to be tapped in structure. But around the structure, you can pay attention to the various characteristics of the whole product, and you can flexibly penetrate the application in a series of fields such as EMC, heat dissipation, noise, safety, environment, ergonomics, DFX(DFM manufacturability, DFI installability, DFA assemblability, DFT testability), and so on, and comprehensively enhance the core competitiveness of the product.
Master class
Being responsible for the core competitiveness of the whole product is your basic work. At the same time, you need to know the relevant domestic and foreign manufacturing standards and norms, know what kind of threshold your products will face when they are sold in Europe or North America, what kind of certification you need to provide, and how you can upgrade your products to meet these needs.
You must also know your competitors' products like the back of your hand, and be able to point out the advantages of each other's short boards and your own products. You know the industry trends, you can predict the development trend of this product in the next five or even ten years, and make a long-term development strategy to guide your staff to accumulate relevant technology.
