I sincerely ask all seniors in the machinery industry to leave valuable suggestions!

Hello, host!

It has been a while since I received your message. I have been very busy during this period, so I originally posted a message stating that I will no longer reply to your questions in the near future, but I can see from your text that You are very sincere, so I hope my words below can help you a little.

You have a lot of questions, and you have excerpted responses from many of my other posts. It can be seen that your current state of mind is quite confusing. The key is that your mind has not calmed down. This is very important for the machinery industry. It's a very negative effect.

So let me sort out your thoughts and hope you understand the following points first:

1. The past is not important

Do you mind your academic qualifications? I care about your major and your school. I understand this. But you have to understand that knowing your shame and then being brave is your motivation, not your pressure. Carrying such a big mental baggage all day long will accomplish nothing. Your words

reveal your dissatisfaction with the current situation, which is good! But at the same time, you are also helpless. This is where I strongly urge you to correct your mentality. Nothing can't be changed. You shouldn't sigh but sneer at the current state of being neither better nor worse. It's just a temporary hero's shortness of breath

2. Believe in yourself

You From your description, I think you are already better than many people. There are many people who hang around doing nothing all day long. If you have had your own experience and you have tried it, it means that you have a certain level of strength. Moreover, you are only a sophomore, and the days ahead are very long. Even if there are some detours, you have enough time to correct your course. .

3. Stick to your beliefs

You have done a good job in this regard. I hope you will not waver in the days to come. The sentence that I appreciate the most in your entire article is:

"Otherwise, how can I support the people I love, how can I support the people I love, and how can I raise the people I love the most!"< /p>

Very good! I hope you will always remember this sentence. As early as 4 years ago, I mentioned a similar sentence in Baidu's reply. I hope you can do the same.

Now let’s share your questions. This only represents my personal opinion. I hope you can treat them differently:

1. Your professional courses

You After all, you are still in school, so you should make good use of this time. From your description, it can be seen that although you copied my reply, you did not understand what I meant.

Advanced mathematics and engineering mathematics are completely different concepts. Advanced mathematics only introduces the concept of calculus, which highly summarizes and summarizes the connection between mathematics and practical engineering from a more abstract level, but it is purely The theory; and engineering mathematics (probability theory and mathematical statistics, linear algebra, complex variable functions, special equations, etc.) are mathematics that are actually used in actual work, which can be calculated, quantified, and can be used for analysis and conclusions. . So if you don't understand why they are called engineering mathematics, then even if you finish reading, it will be in vain. As an engineering major, I am really surprised that your school does not set up corresponding courses.

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

English: Find a way to teach yourself well, there is no other language, only familiarity you.

Engineering Mathematics: Probability Theory and Mathematical Statistics are must-reads. These two courses are not difficult and can be self-study. If you want to combine them with practical applications, you can refer to books on the Six Sigma system. You can also ask me another question, I am a six sigma black belt.

Theoretical mechanics: you only need to memorize the four strength theories, or if you are lazy, you can directly check the four strength theories online

Material mechanics: you only need to memorize a few tables , the tensile and compressive stress change curves of plastic and brittle materials, material failure characteristics, fatigue characteristics and fracture characteristics, etc.

Basics of design: You have professional courses on this, take it well, although in school It's too superficial, but after all, it's a beginner's tutorial for you to get started, so it's still somewhat useful.

Don’t spend energy on the rest. The above will probably take up a lot of your spare time in the future, but the above will at least 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 is useless to just be able to draw. In fact, without a strong mechanical foundation, you will not be able to draw well without drawing. It often takes much longer to mark a drawing than to draw these lines. With so many comments, each sentence has a profound meaning, which is not something that a draftsman can understand. And for normal people, there is no difficulty in drawing skills, which can be completely ignored. So don't spend money to study for any certificate, just study on your own. As for how to become proficient, as I have said in many of my replies, use things around you to practice, such as mobile phones, alarm clocks, phones, TVs, computers... they can all be used for practice. It can be used very well to build three-dimensional models and produce two-dimensional drawings, and there are many good forums online. For actual work, CAD requires very little skills to use. If you can do what I said above by yourself, then your CAD skills are enough.

3. Please don’t bring up the issue of operating machine tools. CNC is powerful, but for so long, I have never seen any company call the people who operate CNC engineers, they are technicians at best. So there is no need for you to ask about my income. Obviously, no matter how superb the real-time CNC operation is, to be honest, the income is not very good and cannot compete with real engineers.

The maintenance of CNC and other machine tools is a completely different field. In this field, there are many talents, and there is no shortage of real masters, and such technical personnel are often real technical engineers and are valuable. You must know that the complexity of these equipment itself is quite high, and the maintenance of these equipment requires very high basic knowledge of the machinery industry and mechatronics industry. If you can develop in this direction, it is a good choice. The income is also very good. Let me give you an example. About 4 years ago, a company was recruiting maintenance engineers for a Siemens exclusive equipment. The monthly salary at that time was 8,000.

4. I have talked about the issue of enterprise selection many times. You should already know my opinion on the specific sequence. What I want to say here is, don’t think that all interviews are scary, and don’t think that the examiners are all interested in defeating you. If I really want to stump some people, I can ask countless questions that the other person can’t answer in one sentence, but In fact we won't do that. For those who are unskilled, the interview is really scary. We only care about how many of the other party's skills can be used by us and whether the other party can create wealth for the company instead of wasting resources.

To facilitate your understanding, I had 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 processes have you used before? What aspect of design is your expertise? What about skills in teamwork and time management? What do you think about project development? If a product requires sealing and impact resistance, what measures will you generally take? ...The other thing is some English issues.

It can be seen that most of the questions we will ask are open-ended and do not have 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 this is easy for capable engineers and it is definitely not difficult.

5. What career path should you take (I must put this at the end, it is too complicated and confusing)

In many of my replies, I have mentioned to career development routes. Obviously you were fooled by your teachers!

I have every reason to believe you. Your school is very ordinary and will not provide you with any good opportunities for your future development. The reason is very simple. As a junior college student, if you are still struggling with machine tool control, what about those friends who have graduated from technical secondary schools? Are you going to compete with them for jobs? What else are you reading?

Since all schools aim at employment rates, asking you to start at such a low starting point just to ensure their employment rate is very detrimental to your personal development.

Maybe your school is not very good, but your major is not bad. Your future path should be in professional fields such as mechanical manufacturing, automated production lines, quality management, product testing, etc., rather than operating machine tools. . So I basically don’t understand a lot of the descriptions you said about CNC and machine tools. I don’t think this is your future development direction, at least not your current development goal.

I don’t want to repeat a lot of the content mentioned above. I have emphasized it repeatedly in many other posts, and I think you have seen it. A higher starting point can save you several years of struggle. It may be difficult at the beginning, but you must have your own confidence, which is what I mentioned at the beginning.

Due to the influx of large amounts of foreign capital into the country in recent years, the popularization of high-tech, automated production, product design and manufacturing, and high-quality control are all very good development directions in the future. You may currently have more exposure to machine tools, which is not a waste, because the mechanical foundation is the same, and a large amount of grassroots experience is also the basis for high-level technical work. Among all the development directions, I recommend you to engage in mechanical manufacturing, because mechanical design is good, but the basic requirements are too high, and after all, the demand is small; machine tool maintenance is a relatively cold field, although the development is good, but the progress This door is not easy. If the master is not right, his life will be ruined. The talent gap in mechanical manufacturing is very large and the demand is also large, but the basic requirements are not very high.

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

Supervise the production line to complete product assembly testing according to standard processes; write reasonable product processes Documents; coordinate unreasonable processes in the product production process; handle conflicts in the product production process; coordinate production plans and adjust corresponding work stations and technical parameters; design tooling fixtures required to complete product assembly and production; handle product production processes Bugs and improvements, etc.

This is the direction I think you should develop in the future. Moreover, you are in Yantai, a place where Japanese and Koreans gather in large numbers. There are also some very good manufacturing companies. This is what you will develop in the future. Target.

You are only a sophomore, so you have enough time to do an internship. Don’t miss it during the holidays and go to the front line of production to accumulate some foundation; for juniors and seniors, you should look for development, manufacturing, and quality in big companies. Wait for the department to conduct internships and go without salary, then when you graduate, you don't have to worry about finding a good job.

Finally, as always, I hope you don’t take too much pressure in your mind in the future. Pressure is pressure, motivation is motivation. Work is not everything in life. I still work when I have free time. When it comes to playing games, there is no conflict at all. Just do what you should do and work towards the normal direction. Only by maintaining a good attitude can we face future challenges. Because then you will know that a well-developed job requires not only strong technical abilities, but also good soft skills. You can also refer to my other posts on this. So while working hard, relax appropriately.

I haven’t had so much nonsense in a long time, just for your reference, thank you!
