Chapter 441: new course

Ding Wenjiang Ding Gong sits in front of a 19-inch crt monitor and feels uncomfortable. He looked down at the keyboard and mouse in front of him, and then looked at the vertical case under the table, his heart filled with absurdity.
Equally absurd are the twenty or so students at Tianyang Yeyuan 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?
The teachers and students were very shy.
The video classroom is newly built, and the cad course is newly opened.
Dozens of computers in the classroom were picked up from the 'garbage dump' the day before yesterday. Many cases are ragged, and nothing looks like high-end goods worth tens of thousands of yuan.
In the 1990s, the West already used CAD software extensively in the industrial field, and Zhou Qingfeng directly used pirated software. Even the textbooks were purchased temporarily from hk.
Tianyang Printing Factory ignored the copyright, and in two days it took hundreds of photocopy plates and sent them to the college. None of the textbooks were translated, which was taught in English.
Ding Gong was the foundry engineer Xiao Jinlang accidentally met on the train.
The domestic scientific research field has long been in the state of 'paying close attention to international advanced technology and striving to fill domestic gaps'.
Ding Gong is doing this. He focuses on the new technology of the foreign foundry industry, and currently focuses on the application of computer cad technology in the industrial field.
The 60-year-old man spent his whole life in a state-owned enterprise in Wuhan. When he was about to retire, he gave up his work to his children.
For now, state-owned enterprises allow their sons to inherit their father's business. In a few years, state-owned enterprises closed down on a large scale, and they would no longer be able to inherit their father's business.
In the 1990s, there was a word called "Zou Xing", just like the traffic artist who performed commercials everywhere in 30 years. But now there are no agents in ‘walking the hole’, and they are capable people running privately.
Mr. Ding retired. He also counted as 'walking holes' in the past two years, mainly helping small local factories to solve casting problems and earn some labor costs.
Casting took place 3,000 years ago, and it is the oldest manufacturing process of mankind. The fine bronzes of ancient times were basically cast.
Compared with machining, casting is cheaper, faster, and larger in quantity, but less accurate.
The use of CAD technology in the field of machinery manufacturing is a huge progress. For example, when designing a mold, an intuitive three-dimensional structure is given, and the drawing is quick, which greatly saves costs and time.
The West began to study CAD in the 1970s. Cooperating with numerical control technology, this makes their industrial products more fine, good quality, low cost and high profit.
The casing of a 50cc gasoline engine made by "Shengguang Machinery" is also cast. However, the accuracy of the mold is poor, and it needs to be processed several times in machining.
However, as long as the number of machining operations is large, this cost cannot be reduced to a certain degree. Especially now that CNC machine tools are not popular, it is more expensive to rely on labor.
When Ding Gong said on the phone that he was studying the application of cad in the foundry field, Zhou Qingfeng was very happy. He immediately clapped a monthly salary of 1,000 to give this baby to Tianyang.
Mr. Ding was very satisfied when he arrived in Tianyang. It was delicious, good to drink and live, much more comfortable than ordinary local small factories.
He also ate the health supplements dispensed by the company. His migraine and old stomach disease for many years did not occur. He was even more energetic and his sleep quality was greatly improved.
Life is good, but is this work?
Ordinary local factories have poor technical strength, and Father Ding will not talk about cad when he goes, mainly to help solve some common casting mold problems.
But Zhou Qingfeng has no shortage of ordinary molds. He knows the potential of computer technology. The backward industrial system will be overthrown, which will greatly reduce product costs.
Since the 1990s, China's casting output has continuously exceeded 10 million tons. Two thousand years later it surpassed the United States to become the number one in the world.
But it would not make a few more money to cast some iron golems. After the country fights for output, the problem of being big but not strong is always inevitable.
Father Ding engaged in cad in his original unit, but the effect was not high. The reason is very simple. The technology for castings in China is backward, the quality of employees is low, and the supporting equipment is vacant.
Even Ding Wenjiang has done several cad PRs in order to write a dissertation, complete tasks assigned by some ministries and commissions.
After it was done, everyone had a meeting, presented the awards, wrote several summary reports, and the results were shelved. As for the actual production, it still uses backward old technology.
I did not expect to arrive in Tianyang, Zhou Qingfeng was really here. The president wants to engage in large-scale computer-aided design and manufacturing, as well as cultivate a group of professionals.
Mr. Ding has a very big head. He has never done this job.
But now the money is taken and the food is eaten, I can only bite the bullet.
This is equivalent to going through all the mechanical processes from the beginning. The original equipment and personnel cannot be used all the way, which is very difficult.
Fortunately, Zhou Qingfeng was not just a slogan leader who did not give enough money to the leadership of the rice bucket. He would not just approve 50,000 R & D expenses as if it were fatal. He also urged scientific researchers to save money.
Zhou Qingfeng didn't interfere in technology, but he knew what was the trend of technology. Dozens of 486s in this classroom alone made Mr. Ding's speech inspiring and shocking.
The feeling of wealth is so cool!
Zhou Qingfeng will not send a group of workers with junior high school culture to R & D for Father Ding, all of them are authentic college students. Although these students are all inexperienced, they have strong learning ability!
CAD technology completely abandons manual drawing. Its essence is the combination of computer and machinery, designing accurate digital models, and then creating accurate parts accordingly.
This places higher requirements on production lines, production equipment, and production workers. Further 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, the state-owned factory can only complete some political projects that fill the gaps in the country, and there is no way to apply them in large quantities.
"It's amazing, it's amazing!"
Touching the mouse in his hand, Mr. Ding laughed joyfully. He visited abroad and saw factories in Japan and Germany.
Workers abroad are well-groomed, sitting in spacious and bright offices. The domestic workers are black like beggars.
Looking at the restless students in the classroom, the old man asked with a smile: "Why don't you seem very happy? Today, this class has caught up with the trend of the times."
A student asked bitterly: "Ms. Ding, shall we learn this casting, and then we will be assigned to the factory as workers?"
Oh ... the symptoms are here.
The old man laughed, "If this kind of worker doesn't need to be exhausted, he just needs to sit in a beautiful office and work with a computer. He can earn seven or eight hundred a month. Can you do it?"
Hahaha ..., a group of students immediately laughed.
Casting workers are all working at high temperatures, doing manual work and harsh working conditions, but they do not have high academic qualifications. The average factory's wages for this kind of job do not attract good practitioners at all.
Mr. Ding was very clear about the students' thoughts. He grabbed the photocopy of the textbook in his hand. "The domestic mechanical drawing is still largely manual, but computers have been used abroad.
I also don't have much experience to teach you. Now we can only figure it out by ourselves and see how European and American countries do it?
I know that the metallurgical institute has begun to use computers to replace manual drawing, and the efficiency improvement is extremely obvious. This is a lifelong skill that can be used after learning.
You are luckier than me because I am old. I only have past experience and you will have the future
As long as "Sacred Light" can continue to invest in this industry, the domestic voice in this industry will probably be in the hands of some of you.
Work hard, classmates. Look forward to the future! "
