Please leave valuable suggestions for the predecessors in the machinery industry!

It's been a while since I received your message, and I'm very busy during this time, so I have posted a statement that I won't reply to your question in the near future, but I can see from your words that you are sincere, so I hope my following words can help you a little.

You have a lot of questions, and you have also extracted many replies from other posts. You see, your current state of mind is rather chaotic. The key is that your heart has not calmed down, which is very negative for the machinery industry.

So I'll sort out your thoughts, and I hope you understand the following points first:

1. The past is not important.

I understand that you care about your education, your major and your school. But you have to understand that this is your motivation, not your pressure. Carrying such a heavy mental burden all day will accomplish nothing. In your words,

Just show your dissatisfaction with the status quo! But at the same time, you are helpless, which I strongly urge you to correct your mentality. Nothing cannot be changed. You should not sigh at the current stuck state, but sneer at it. It's just a moment of heroic shortness of breath.

2. Believe in yourself

In your description, I think you are better than many people. There are many people who do nothing all day. You have had your own experience, and you have tried it, which shows that you have certain strength, and you are only a sophomore, and the days behind you are very long. Even if you take some detours, you still have enough time to correct your route.

Stick to your beliefs.

You have done a good job in this matter. I hope you will not waver in the future. What I admire most about you is:

"Otherwise, how can I support my beloved, my beloved and my favorite!"

Very good! I hope you will always remember this sentence. As early as four years ago, I mentioned a similar sentence in Baidu's reply I hope you can do the same.

Now share your question, which only represents my personal opinion. I hope you can treat it differently:

1. Your main course

After all, you are still at school, so make good use of this time. As you can see from your description, although you copied my reply, you didn't understand what I meant.

Higher number and engineering mathematics are completely different concepts. Higher number only introduces the concept of calculus, which highly summarizes the relationship between mathematics and practical engineering from a more abstract level, but it is a pure theory. And engineering mathematics (probability theory and mathematical statistics, linear algebra, complex variable functions, special equations, etc.). ) Really used in practical work, it can be calculated, quantified and analyzed. So if you don't understand why they are called engineering mathematics, it's no use reading them even if you finish reading them. As an engineering course, I am really surprised that your school doesn't offer corresponding courses.

For the future, you may have to make up for it by a lot of self-study, so my recommendation is:

English: Try to teach yourself. There is no other language except proficiency.

Engineering Mathematics: Probability Theory and Mathematical Statistics are required reading. These two courses are not difficult and can be taught by yourself. If you want to combine practical application, you can refer to the books of Six Sigma System. You can also ask me, I am the Six Sigma Black Belt.

Theoretical mechanics: You only need to memorize the four strength theories, or, if you are lazy, you can look them up directly on the Internet.

Mechanics of materials: only a few tables need to be memorized, such as tensile and compressive stress curves of plastic and brittle materials, material failure characteristics, fatigue characteristics and fracture characteristics.

Fundamentals of design: You have a special course in this field. Take it well. Although it is too superficial in school, it is still a primary course for you to get started, and it is still useful.

Don't spend the rest. I'm afraid the above will take up a lot of your spare time in the future, at least it will ensure that you won't be overwhelmed by problems in the future.

2. Questions about CAD and various certificates

I have mentioned in countless replies that CAD certificates are useless! It only takes a few days to teach you how to use a software, but I have emphasized the difference between a draftsman and a designer countless times. It's no use just drawing. In fact, without a strong mechanical foundation, you can draw well without drawing. The drawing time of a painting is often much longer than drawing these lines. There are so many notes, and every sentence has profound meaning, which is beyond the comprehension of a draftsman. And for normal people, drawing skills are not difficult and can be completely ignored. So don't spend money to read any certificates, just teach yourself. As for how to be proficient, I have said in many replies that you can practice your hands with things around you, such as mobile phones, alarm clocks, telephones, televisions and computers. Building 3D models and making 2D drawings can be used very well, and there are many good forums on the Internet. For practical work, CAD requires very few skills. If you can do what I said above by yourself, then your CAD skills are enough.

Please don't mention the operation of machine tools. CNC is powerful, but for a long time, I have never seen any company call CNC operators engineers, at best, technicians. So you don't have to ask me about my income. Obviously, the real-time CNC operation is superb, and to be honest, the income is not so good, so it can't be compared with real engineers.

CNC and other machine tool maintenance are completely different fields. There are many talents in this field, and there are many real masters, and such technicians are often technical engineers with real gold content. You should know that the complexity of these devices is quite high, and the maintenance of these devices requires quite high basic knowledge of machinery industry and mechatronics industry. If we can develop in this direction, it is a good choice and the income is also very good. Let me give you an example. About four years ago, a company recruited a maintenance engineer for an exclusive Siemens equipment with a monthly salary of 8,000 yuan.

I have said many times about the choice of enterprises, and you should already know my opinion about the specific order. What I want to say here is, don't think the interview is scary, and don't think the examiner is willing to hit you. If you really want to impress some people, I can ask countless questions that make them unable to answer a word, but in fact we won't do that. For ignorant people, the interview is really scary. We only care about how many skills the other party can use for us, and whether the other party can create wealth for the company instead of wasting resources.

For your understanding, I made an interview yesterday and asked the following questions (the other party applied for a structural design engineer):

How is your CAE analysis ability? What product development process have you used before? Where was your major designed? How about teamwork and time management? How to treat project development? If a product requires sealing and strength and impact resistance, what measures do you usually take? ..... The other is some English problems.

It can be seen that most of the questions we will ask are open-ended and there are no accurate answers, and these answers can fully reflect your overall strength and ability. If you don't have the corresponding experience, you will still get stuck, but I think it is easy for a capable engineer, and it is certainly not difficult.

5. What kind of career path should I take (I have to say this at the end, it's too complicated and messy)

In many of my replies, I mentioned the issue of career development route. Obviously, you were fooled by the teacher!

I have every reason to believe what you said. Your school is very ordinary and will not provide you with any good opportunities for future development. There is a simple reason. As a junior college, if you still spend time on machine tool control, what about those friends who graduated from secondary school? Are you going to grab a job with them? What other books do you read?

Since all schools aim at the employment rate, it is very unfavorable for your personal development to start from such a low starting point just to ensure their employment rate.

Maybe your school is not so good, but your major is not bad. Your future career should be in the fields of mechanical manufacturing, automatic production line, quality management, product testing and so on, and definitely not to operate machine tools. So as for many descriptions of CNC and machine tools you said, I basically don't read them. I don't think this is your future development direction, at least not your current development goal.

I don't want to repeat many things mentioned above. I have repeatedly stressed it in many other posts, and I think you have seen it. A higher starting point can save you a few years of struggle. It may be difficult to walk at first, but you should have your own confidence, which is what I mentioned at the beginning.

Due to the influx of foreign capital into China in recent years, the popularization of high technology, automatic production, product design and manufacturing, and high quality control are all very good development directions in the future. At present, you may have a lot of contact with machine tools, which is not a waste, because the mechanical foundation is the same, and a lot of grass-roots experience is also the foundation of high-level technical posts. In all the development directions, I recommend you to engage in mechanical manufacturing, because the mechanical design is good, but the requirements for the foundation are too high, after all, the demand is small; Machine tool maintenance is a relatively cold field. Although the development is good, it is not easy to get into this door. If the master is wrong, he will ruin his life. However, there is a big talent gap in mechanical manufacturing, and the demand is also large, but the basic requirements are not very high.

Typical job functions of mechanical manufacturing: (for your reference, after all, different companies are different)

Supervise the production line to complete the product assembly test according to the standard process; Prepare reasonable product process documents; Coordinate unreasonable processes in product production; Handle conflicts in the production process of products; Coordinate production plan and adjust corresponding stations and technical parameters; Design fixtures for product assembly and production; Deal with the mistakes in the production process and improve them, and so on.

This is the direction I think you should develop in the future, and you have some very good manufacturing enterprises in Yantai, a place where Japanese and Koreans gather in large numbers. These are your future development goals.

You are only a sophomore, so you have enough time to practice. Don't miss it when you have a holiday, and accumulate some foundation for production. Junior and senior students should go to the development, manufacturing and quality departments of big companies for internships without pay, so they don't have to worry about finding a good job when they graduate.

Finally, as usual, I hope you won't give yourself too much psychological pressure in the future. Pressure is pressure, motivation is motivation, and work is not the whole of life. I still play games when I am free now, which is completely conflict-free. Just do what you should do and work hard in the normal direction. Only by keeping a good attitude can we face the challenges in the future. Because then you will know that a well-developed job requires not only strong skills but also good soft skills. You can also refer to my other posts. So while working hard, relax appropriately.

I haven't had so much nonsense for a long time, for your reference only, thank you!
