Ding Wenjiang, Ding Wenjiang, was sitting upright in front of a 19-inch CRT monitor, feeling uncomfortable all over. He lowered his head and looked at the keyboard and mouse in front of him, then looked at the vertical chassis placed under the table, and felt a sense of absurdity in his heart.
.
What is equally ridiculous are the twenty dozen students from Tianyang Metallurgical Institute in front of Ding Gong. They are all metallurgical majors. They are sitting in the newly built electronic classroom and carefully moving the mouse in their hands, but they don’t know what to do?
Teachers and students were confused.
The electronic classroom is newly built, and the CAD course is also newly opened.
Dozens of computers in the classroom were picked out from the trash dump just the day before yesterday. Many of the cases were in tatters and looked nothing like high-end products worth tens of thousands of yuan.
In the 1990s, CAD software was widely used in the industrial field in the West, but Zhou Qingfeng directly used pirated versions. Even the teaching materials were temporarily purchased and sent from HK.
Tianyang Printing Factory ignored copyright and produced hundreds of sets of photocopies in two days and sent them to the college. The textbooks were not translated, so all teaching was in English.
Ding Gong was the foundry engineer Xiao Jinlang accidentally met on the train.
The domestic scientific research field has long been in a state of 'keeping a close eye on international advanced technologies and striving to fill domestic gaps'.
This is what Ding Gong does. He is focusing on new technologies in the foreign foundry industry. Currently, he is focusing on the application of computer CAD technology in the industrial field.
This old man in his sixties has worked in a state-owned enterprise in Wuhan all his life. When he was about to retire, he gave up his job to his children.
It's good now that state-owned enterprises still allow sons to inherit their father's business. In a few years, state-owned enterprises will go bankrupt on a large scale, and it will be impossible to inherit their father's business.
In the 1990s, there was a word called "acupoint walking", which was just like the popular artists thirty years later who performed commercially everywhere. But now, there are no managers for "acupoint walking", and they are all capable people running around privately.
Mr. Ding has retired and has been doing some "working out" in the past two years. He mainly helps some local small factories solve casting problems and earns some labor fees.
Casting began three thousand years ago and is the oldest manufacturing process of mankind. Most of the exquisite bronzes in ancient times were cast.
Compared with machining, casting is cheaper, faster, and larger in quantity, but the accuracy is lower.
The use of CAD technology in the field of mechanical manufacturing is a huge progress. For example, when designing molds, it provides an intuitive three-dimensional structure and quickly produces drawings, which greatly saves cost and time.
The West began to study CAD in the 1970s. Coupled with CNC technology, this made their industrial products more precise, of better quality, with lower costs and higher profits.
The 50CC displacement gasoline engine casing manufactured by 'Shengguang Machinery' is also cast. However, the mold accuracy is poor and requires multiple machining processes.
But as long as the number of machining operations increases, the cost cannot be reduced to a certain extent. Especially now that CNC machine tools are not yet popular, it is even more expensive to rely on labor.
When Ding Gong said on the phone that he was studying the application of CAD in the casting field, Zhou Qingfeng was extremely happy. He immediately decided to invite this precious old man to Tianyang with a monthly salary of one thousand.
Mr. Ding is very satisfied with his visit to Tianyang. It has good food, drink and good accommodation. It is much more comfortable than ordinary local small factories.
He also took some health supplements distributed by the company, and his migraines and stomach problems that he had suffered for many years have disappeared. He is even more energetic and his sleep quality has also been greatly improved.
Life is good, but is this a job?
Ordinary local small factories have poor technical capabilities. Mr. Ding didn't know much about CAD when he went there. He mainly helped solve some mold problems for ordinary castings.
But Zhou Qingfeng has many people working on ordinary molds, and he is very aware of the potential of computer technology. The backward industrial system will be overturned as a result, and product costs will be greatly reduced.
Since the 1990s, China's casting output has continuously exceeded 10 million tons. Two thousand years later, it surpassed the United States and became the world's largest.
But you can't make much money just by being able to cast some iron lumps. After the country strives for production, the problem of big but not strong cannot be avoided.
Mr. Ding engaged in CAD in his original unit, but the results were not high. The reason is very simple. The technology of domestic castings is backward, the quality of employees is low, and there are a large number of vacancies in supporting equipment.
Even Ding Wenjiang engaged in CAD public relations several times in order to write papers and complete tasks assigned by ministries and commissions.
After the work is completed, everyone holds a meeting, awards awards, writes a few summary reports, and the results are shelved. As for the actual production, we still use outdated and old processes.
Unexpectedly, when they arrived in Tianyang, Zhou Qingfeng was serious. This CEO wanted to engage in large-scale computer-aided design and manufacturing, and also cultivate a group of professional talents.
Mr. Ding has a big head and has never done this job before.
But now that I have money and food, I have no choice but to bite the bullet.
This is equivalent to starting all the mechanical processes from scratch, and all the original equipment and personnel cannot be used, which is very difficult.
Fortunately, Zhou Qingfeng is not a leader who only shouts slogans but does not provide enough funds. He will not approve only 50,000 yuan of research and development expenses as if it is life-threatening, but also urges scientific researchers to save some money.
Zhou Qingfeng does not meddle in technology, but he understands what is a technological trend. Just the dozens of 486s in this classroom made Mr. Ding feel excited and shocked beyond words.
It feels so good to be rich!
Zhou Qingfeng will not send a group of workers with junior high and high school education to Mr. Ding to do research and development. The workers who come are all authentic college students. Although these students have no experience, they have strong learning ability!
CAD technology completely abandons manual drawing. Its essence is the combination of computers and machinery to design accurate digital models and then create precise parts accordingly.
This puts forward higher requirements for production lines, production equipment, and production workers. Extensive management is simply not feasible and requires large-scale technology investment and personnel training.
The key is that many equipment can only be imported. Therefore, state-owned factories can only complete some political projects to fill domestic gaps, and there is no way to apply them in large quantities.
"It's amazing, it's really amazing!"
Touching the mouse in his hand, Mr. Ding laughed happily. He visited foreign countries and saw factories in Japan and Germany.
Foreign workers are all neatly dressed and sitting in spacious and bright offices to work. Domestic workers are as dark as beggars.
Looking at the restless students in the classroom, the old man asked with a smile: "Why don't you seem very happy? Today's class has caught up with the trend of the times."
One student asked with a grimace: "Teacher Ding, if we learn this casting, will we be assigned to be workers in factories in the future?"
Oh..., the symptoms are here.
The old man smiled and said: "If this kind of worker does not need to work hard, but only needs to sit in a beautiful office and work on a computer, and can earn seven to eight hundred a month, can you do it?"
Hahaha..., a group of students laughed immediately.
Foundry workers work at high temperatures, do physical work, and have harsh working conditions, but they do not require high academic qualifications. The wages offered by general factories for such positions simply cannot attract outstanding practitioners.
Mr. Ding knew what the students were thinking very well. He grabbed the photocopied textbook in his hand and said, "Currently, a lot of mechanical drawing in China relies on manual work, but computers have begun to be used abroad.
I don’t have much experience to teach you. Now we can only rely on ourselves to explore and see what European and American countries do?
I know that Yeyuan has begun to use computers to replace manual drawing, and the efficiency has been greatly improved. This is a skill that can be used throughout your life once you learn it.
You are luckier than me because I am old. I only have past experience and you will have the future
As long as 'Holy Light' can continue to invest in this industry, the right to speak in this industry in China in the future is likely to be in the hands of a few of you.
