"But do you need a copy mill?"

Xiao Wenjun looked at Tang Zifeng and asked.

Tang Zifeng was stunned for a moment and then reacted. An important premise of copy milling machine processing is to manufacture a model or mold first. In the case of a key, you must have an old key before you can make a new one.

The profiling machine used in the factory is mainly used to make workpieces with complex shapes, and people can first make a model out of wood, which is called molding. Wood is easy to carve, so it is easy to make a model out of wood, and the machine tool can then carve on the metal according to the shape of the wood mold, and the complex curved surface can be processed.

But now Tang Zifeng wants to do a wood carving machine tool, if you use a copy milling machine, it means that the craftsman needs to carve a wooden board first, and then use the machine tool to carve another wooden board according to the pattern on this wooden board, isn't this an extra move?

Of course, if someone wants to open a carving factory, first make a mold by hand, and then use a machine tool to make hundreds or thousands of the same product, it is natural to do this. But how many carving factories can there be in the country? Besides, there are also special woodworking machine tools in the industry, and it is estimated that this kind of profiling machine tool for carving has long been available, and it is not worth it to bother to open up this market.

Xiao Wenjun looked at Tang Zifeng's eyebrows and furrowed for a moment before they opened, and knew that he had understood what he meant, so he continued: "You said that you were inspired by the carpenter's carving when your family built the house, so you thought of developing such a machine tool. I think that the carpenter carving in the countryside must not be the same, and if the carvings are the same in every household, everyone will definitely feel uncomfortable.

"When a carpenter carves flowers for each family, he should use several patterns to combine them to make the carved plate patterns look different. In this way, the idea of copy milling machine is not feasible and must be found in another way. ”

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

Like Zhao Yuntao and Liu Xiaohan, who only know how to program, but have to rely on machines to make a living, they are not worthy of being called a scholar at all. Only like Xiao Wenjun, who can not only design machines, but also think more deeply than customers, is called a real scholar.

Replaced by Tang Zifeng, of course, he can also think of this problem. But it's a pity that he doesn't understand machinery, and even the concept of copy milling machine is just in contact, so he naturally can't think of such a deep depth. If it weren't for Xiao Wenjun's wit, seeing this problem, he stupidly went back and let Linyi machine try to make a woodworking profiling machine tool, it would be a joke.

"So, I think what you want is a machine tool that can engrave according to the drawings, just enter the drawings and carve any pattern you want. With such a machine, the skills of the country carpenters will be taken to the next level, and not only will the house builders 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 and help people carve portraits, just like some people draw sketches on the street, we are engaged in three-dimensional sketches, and it is not a problem to collect 180 yuan for a carved plate." ”

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

"Don't worry, sister!" Tang Zifeng hurriedly dragged Xiao Wenjun's thoughts back, and he asked, "So, you mean that you have solved this problem?"

Xiao Wenjun nodded, shook his head again, and said, "I actually only solved part of it. Engraving with ready-made drawings is in principle simpler than profiling a machine. The profiling machine tool needs to convert the displacement signal of the contact into an electrical signal, and if there is a drawing, the electrical signal can be generated directly, and the part of the profiling can be omitted. ”

"yes, isn't that simpler?" Tang Zifeng woke up again, and the feeling of distress came up again. Why did you promise a reward of 10,000 yuan, how good it is to save this money. I have a younger sister and a niece to raise, one is 18 and the other is 15...... , hey, did he move around too much with Han Weichang and contracted his nagging.

Xiao Wenjun glanced at Tang Zifeng and continued: "If the patterns to be carved are all right-angled edges, then there is indeed no problem. How to represent this arc on the drawing, how to convert it into the feed trajectory of the milling head, and what kind of feed strategy to adopt in the case of different milling depths all need to be designed. In the past three days, I didn't get a full 10 hours of sleep and skipped several classes just to solve these problems. ”

"I see. Tang Zifeng listened to it and half understood, but at least he understood that these things were very complicated, and if he was not a professional, he would definitely not have thought of it so deeply. He asked, "So, you've got the problem out." ”

Xiao Wenjun said: "This problem has been solved. I designed a set of drawing specifications myself, stipulating the annotation methods of various transition surfaces, and then on the basis of this specification, I designed the passing strategy of the milling head. As long as the drawings are generated according to my specifications, the engraving machine will be able to carve out the pattern perfectly, with the shortest processing time and the least wear and tear on the milling head. ”

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

"Yes. ”

"No one has done it before?"

"Probably not. ”

"So, have you considered applying for a patent?"

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

"It's so needed!" Tang Zifeng said, "I heard you say this just now, and I am now very optimistic about the prospects of this engraving machine." I estimate that there is no problem with selling 2,000 units a year, and this is not counting exports, but if exports are counted, there is hope for 10,000 units a year. If such a product does not apply for a patent for the core technology, it is just a matter of letting others copy it. In case someone has bad intentions and preemptively registers a patent, we have to pay him the patent fee when we go back, then we will be wronged. ”

"You're saying that if you have a patent, you can charge royalties?"

"Of course you can!" Tang Zifeng said, "With a patent, if our factory wants to produce this kind of machine tool, we have to obtain your authorization." Let's assume that the patent license fee is calculated at 10 yuan per unit, how much is it a year?"

"20,000?" Xiao Wenjun was a little surprised, she calculated according to what Tang Zifeng said about 2,000 units a year, as for the overseas market or something, she felt that it was still a little far away.

"Uh......" Tang Zifeng was a little disappointed, thought about it, and changed his words again: "How can 10 yuan for one unit be enough, how can you get 100 yuan for one! 1 million patent fees a year is the minimum." ”

"Why do I think you're trying to lie to me again?" Xiao Wenjun said vigilantly.

"What do you mean, when did I lie to you in the past?" Tang Zifeng said 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 yuan for me, so that I can scrape together enough money to buy a notebook, I will be content." ”

"Laptops are not a problem. Tang Zifeng said, "That's it, I'll find someone to handle the patent application, and you can write an authorization document to me later." After the patent application is applied for in the future, I will also be responsible for finding someone to handle the patent authorization, and I will get a 20% commission on the patent fee, what do you think? Also, don't you want 10,000 yuan, I will pay you first, and the patent authorization fee will be deducted from it in the future. If the patent is not licensed, the money will be kindly sponsored by me. ”

"This ......" Xiao Wenjun hesitated a little. Tang Zifeng said that the conditions were too good, which made it a little difficult for her to refuse. In particular, Tang Zifeng promised to give her 10,000 yuan to buy a laptop first, which was very attractive to her.

However, it seemed a little too big for her imagination. When she went out in the morning, she was still a female college student who was saving money to buy a notebook, and in a blink of an eye, someone told her that she might earn a million a year, and no matter how she thought about it, it smelled unreliable.

But if you want to say that this Senior Brother Tang in front of you is unreliable, it doesn't seem to be. She had heard Bao Nana talk about Tang Zifeng's company in the past, and now sitting in Tang Zifeng's company office, the visual impact of those dozens of computers was very strong, which made her have to believe in Tang Zifeng's ability.

Perhaps, he can really do this? 1 million a year, 20% to Senior Brother Tang, and he still has 800,000 left, so he can buy 30 notebooks, using IBM on the 1st, Compaq on the 2nd, and 3rd every month......

"Senior Brother Tang, listen to me, there is still a big problem with this equipment, and I can't solve it at present. ”

Xiao Wenjun only fantasized for a few seconds, and then returned to reality, she said:

"As I said, it has to work, but only if you have drawings that are designed to the specifications that I have defined. But if you think about it, a carpenter in the countryside, will he draw in CAD?

"I'm currently thinking of a compromise method, that is, your factory is looking for someone to design some patterns and make them into a model library. These carpenters just need to learn to extract ready-made models from the model library to produce. You can also update this library in the future, so that the machine has the ability to process different patterns. ”

"Are you saying that if you want to design your own patterns, you have to learn CAD?" Tang Zifeng asked.

Xiao Wenjun nodded: "Yes, but I don't think it's realistic." ”

"Why?" Tang Zifeng asked confidently.

"Why? Using CAD also requires technology!" Xiao Wenjun retorted dissatisfiedly, "At the level of those engineers in your Linyi Technology Department, it is difficult to learn CAD, how can you let some country carpenters learn it?"

Tang Zifeng said with a smile: "It's very simple, let's change the CAD to a fool's style, as long as you need simple training, you can learn it." You're waiting......"

Speaking of this, he took out his mobile phone, dialed a number, and then said to the other party domineeringly: "Senior Sister Li, there is a great opportunity now, if you want to seize this opportunity, take your two 'Ou' and rush to the teaching building of Liulangzhuang Primary School within half an hour, and it will not be outdated!"
