When will I have a long tassel?

"But, do you need a copy milling machine?"

Xiao Wenjun looked at Tang Zifeng and asked.

Tang Zifeng was stunned for a moment and then came to his senses. An important prerequisite for copy milling machine processing is to first create a sample or master. In terms of key matching, you must first have an old key before you can copy a new key.

The profiling machine tools used in factories are mainly used to manufacture workpieces with complex shapes. People can first make a model out of wood, which is the so-called prototype. Wood is easy to carve, so it is easy to use wood to make models. The machine tool can then carve on the metal according to the shape of the wooden model to complete the processing of complex curved surfaces.

But what Tang Zifeng wants to do now is wood carving machine tools. If a copy milling machine is used, it means that the craftsman needs to carve a wooden board first, and then use the machine tool to imitate the pattern on this wooden board to carve another wooden board. Isn't this unnecessary? ?

Of course, if someone wants to open a carving factory, they can first make a mold by hand and then use machine tools to make hundreds or thousands of identical products. But how many carving factories can there be in the country? Besides, there are also people in the industry who specialize in woodworking machine tools. It is estimated that this kind of profiling machine tools for carving have been around for a long time. It is not worth the effort for Linyi Machine to develop this market.

Xiao Wenjun saw Tang Zifeng's eyebrows furrowed for a moment and then knew that he understood what he meant, so he continued: "You said that day that you were inspired by the carpenters' carvings when your family was building a house, and then you thought of developing such a Machine tools. I think that carpenters in the countryside must not be the same when carving. If the carvings in every household are the same, everyone will definitely feel uncomfortable.

"When carving for each house, the carpenter should use several combinations of patterns to make the carved board patterns of each house look different. In this way, the idea of ​​copying milling machines is no longer feasible, and another approach must be found."

"Cow!" Tang Zifeng gave Xiao Wenjun a thumbs up and praised sincerely.

What is a top scholar? People like Zhao Yuntao and Liu Xiaohan who only know how to program but are forced to make a living by installing machines for others are not worthy of being called top academics at all. Only people like Xiao Wenjun who can not only design machines but also think deeper than customers can be called true academics.

If it were Tang Zifeng, he would of course be able to think of this problem. But it's a pity that he doesn't understand mechanics, and even the concept of copy milling machine is new, so naturally he didn't expect to go so in-depth. It would have been a joke if Xiao Wenjun hadn't been smart enough to see this problem and stupidly went back to let Linyi Machinery trial-produce a woodworking profiling machine tool.

"So, I think what you want is a machine tool that can carve according to the drawings. As long as you input the drawings, you can carve any pattern you want. With such a machine, the skills of those rural carpenters will be Jumping up to the next level, not only will the builders of houses ask them to carve flowers, but they can also carve furniture, signs, and even handicrafts." Xiao Wenjun said.

"Yes, that's right." Tang Zifeng said, "For example, you can set up a stall on the street to carve portraits for people, just like some people draw sketches for people on the street. What we do is a three-dimensional sketch, a carving board. It won’t be a problem to collect a hundred and eighty yuan.”

"I really didn't think so far ahead." Xiao Wenjun said, her eyes began to become blurred, and she may have begun to think about the technique of carving portraits.

"Don't worry, sister!" Tang Zifeng quickly pulled Xiao Wenjun back from his thoughts and asked: "So, you mean, you have solved this problem?"

Xiao Wenjun nodded, shook his head and said, "I actually only solved part of the problem. Using ready-made drawings for engraving is simpler in principle than a profiling machine tool. The profiling machine tool needs to convert the displacement signal of the contact into an electrical signal. And if there are drawings, electrical signals can be generated directly, and the profiling part can be omitted."

"Yes! Wouldn't that be simpler?" Tang Zifeng woke up again, and the feeling of distress came up again. Why did I promise a reward of 10,000 yuan? It would be great to save this money. I have a sister and a niece to support, one is 18, the other is 15... Hey, maybe I have been walking around too much with Han Weichang and contracted his nagging habit.

Xiao Wenjun rolled his eyes at Tang Zifeng and continued: "If the patterns to be carved are all right-angled edges, then there is really no problem. But when carving, the transition of the petals should be arc-shaped, right? How does this arc look on the drawing? Performance, how to convert it into the feed trajectory of the milling head, and what kind of feed strategy to adopt when the milling depth is different, all need to be designed. In the past three days, I have not slept for a total of 10 When I was young, I skipped several classes just to solve these problems.”

"That's it." Tang Zifeng half-understood what he heard, but at least he understood that these things are very complicated. If you are not a professional, you would never think of it being so deep. "So you've solved the problem," he asked.

Xiao Wenjun said: "This problem has been solved. I designed a set of drawing specifications myself, stipulating the marking methods of various transition surfaces, and then based on this specification, I designed the tool feeding strategy of the milling head. As long as I follow my According to the drawings generated according to the specifications, the engraving machine can perfectly carve out the pattern, with the shortest processing time and the least wear and tear on the milling head."

"You mean, you designed this yourself?" Tang Zifeng asked in surprise.

"yes."

"No one has done it before?"

"I think should not be."

"So, have you ever considered filing for a patent?"

"Patent?" Xiao Wenjun was stunned, "Does this also need to be patented?"

"It's so needed!" Tang Zifeng said, "After hearing what you said just now, I am now very optimistic about the prospects of this kind of engraving machine. I estimate that there will be no problem in selling 2,000 units a year. This does not count exports. If it counts There is a hope of exporting 10,000 units a year. If you don’t apply for a patent on the core technology of such a product, it will be fine and let others copy it. If someone has bad intentions and registers the patent, we will still have to pay him the patent fee later. , that would be unjust."

"You mean, if you have a patent, you can charge royalties?"

"Of course!" Tang Zifeng said, "With the patent, if our factory wants to produce this kind of machine tool, it must obtain your authorization. Let's assume that the patent authorization fee is calculated as 10 yuan per machine. How much does it cost per year?"

"20,000?" Xiao Wenjun was a little surprised. She calculated it based on Tang Zifeng's 2,000 units a year. As for overseas markets, she felt it was still a bit far away.

"Uh..." Tang Zifeng was a little disappointed. After thinking about it, he changed his mind and said: "Ten yuan is not enough for one machine, why should it be 100 yuan for one? One million patent fees a year is the minimum."

"Why do I think you are trying to lie to me again?" Xiao Wenjun said warily.

"What do you mean? When have I lied to you in the past?" Tang Zifeng asked angrily.

"Then why did you lie to me this time?"

"Because... I didn't lie to you this time!"

"I don't believe it." Xiao Wenjun shook his head and said, "Besides, I don't want 1 million a year. As long as you can apply for a design fee of 10,000 for me and let me collect enough money to buy a notebook, I will be satisfied."

"The laptop is not a problem." Tang Zifeng said, "Let's see, I will find someone to handle the patent application, and you can write an authorization document to me later. After the patent application is completed in the future, I will also be responsible for finding someone to handle the patent authorization. , I will commission 20% of the patent fee, what do you think? Also, don’t you want 10,000 yuan? I will pay you first and deduct it from the patent licensing fee in the future. If the patent is not authorized, this money will be regarded as my friendship. Sponsored for you.”

"This..." Xiao Wenjun hesitated. The conditions mentioned by Tang Zifeng were so good that it was hard for her to refuse. In particular, Tang Zifeng promised to give her 10,000 yuan to buy a laptop, which was very attractive to her.

However, this matter seemed a bit too big, beyond her imagination. When she went out in the morning, she was still a female college student who was saving money to buy a laptop. In the blink of an eye, someone told her that it was possible to make a million a year. No matter how she thought about it, she felt unreliable. smell.

But if you want to say that Senior Brother Tang in front of you is unreliable, it doesn't seem to be the case. She had heard Bao Nana talk about Tang Zifeng's company in the past. Now sitting in Tang Zifeng's company office, the visual impact of dozens of computers was so strong that she had to believe in Tang Zifeng's ability.

Maybe, he can really do this? 1 million a year, give 20% to Senior Brother Tang, and I have 800,000 left, so I can buy 30 laptops, IBM on the 1st of every month, Compaq on the 2nd, and Compaq on the 3rd...

"Senior Brother Tang, listen to me, there is another big problem with this equipment that I can't solve at the moment."

Xiao Wenjun only fantasized for a few seconds and then returned to reality. She said:

"I just said that for it to work, it must have drawings designed according to the specifications I defined. But think about it, do carpenters in the countryside know how to use CAD to draw?

"I am currently thinking of a compromise method, that is, your factory will hire people to design some patterns and make them into a model library. These carpenters only need to learn to extract ready-made models from the model library for production. You can also update this in the future Model library, so that the equipment has the ability to process different patterns.”

"You mean, if you want to design your own patterns, you must learn CAD?" Tang Zifeng asked.

Xiao Wenjun nodded: "Yes, but I don't think this is realistic."

"Why?" Tang Zifeng asked confidently.

"Why? Using CAD also requires skills!" Xiao Wenjun retorted dissatisfied, "As far as the engineers in your Linyi Machinery Technology Department are at, it is difficult to learn CAD. How can you ask some rural carpenters to learn it?"

Tang Zifeng smiled and said: "It's very simple. Let's change the CAD into a fool-like one. You can learn it with simple training. Just wait..."

At this point, he took out his mobile phone, dialed a number, and then said domineeringly to the other party: "Senior Sister Li, there is an excellent opportunity now. If you want to seize this opportunity, bring your two Europeans with you." ', get to the teaching building of Liulangzhuang Primary School within half an hour, don't wait if you are late!"
