Chapter 290 Upgrading the Machine Tool Again
"That's right. You tortured me to death last night, but now you refuse to admit it. Isn't this abusing me?"
"That's right! A man cannot default on his debts after marrying a wife. Besides, you guys are already doing that, so you can't be irresponsible!"
Yi Zhonghai became increasingly nervous when he saw the situation getting more and more serious.
If you continue like this, you will definitely be accused of "seducing and abandoning someone".
In desperation, Yi Zhonghai could only make up his mind and said to Jia Zhang: "Okay! Today I will let you see who is the real man! Let's go to the street office now!"
After saying this, he grabbed Jia Zhang without saying anything and dragged her out without looking back.
Jia Zhang was stunned at first, then she smiled triumphantly.
She turned around and waved at the crowd, shouting arrogantly: "Wait! When Auntie comes back, I'll treat you to a wedding banquet!"
Just like that, the man and the pig left angrily, leaving the crowd looking at each other and talking about it.
Alas, these days are really different every day.
……
At the same time, in an experimental field not far from the courtyard, Li Yangzheng and Sun Delin, the head of the affiliated farm, were standing next to the rice fields, looking out at the endless green ocean.
Although it has only been over a month since the seeds were sown, the rows of rice have already grown lush and green, and the fields are full of greenery and vitality.
"Mr. Li, look at how well the rice seedlings are growing!" Sun Delin pointed to the field excitedly, his face filled with a happy smile, "In just one month, they are already half a head taller than ordinary rice seedlings!"
"Yes, it's really pleasing." Li Yang nodded, and looked at the lush and tall rice seedlings, and couldn't help revealing a look of satisfaction.
As a time traveler, he is well aware of the importance of food production to a country.
Especially in this era, having enough food to eat is still a problem.
Therefore, we choose the highest quality varieties in the small world.
Just in one month, the trial hybrid rice showed amazing growth potential.
The seedlings were all green and tall, with well-developed root systems, thick leaves and sturdy stems, without any signs of disease or insect pests.
"Mr. Li, I really don't know how to thank you." Sun Delin's eyes were red, and he held Li Yang's hand tightly.
"Not only did you send us seeds, you also taught us how to improve the soil and plant scientifically. I'm sure we'll be able to have a good harvest in no time from this acre of land."
Li Yang smiled and patted his shoulder, comforting him: "Uncle Sun, our farm is what it is today thanks to your decades of hard work. My little help is nothing."
"No way!" Sun Delin waved his hands, "We will never forget the great contributions you have made to our farm!"
He suddenly remembered something, took out a cloth bag from his pocket and handed it to Li Yang attentively.
"By the way, Mr. Li, I kept some of the wheat seeds you sent me last time to sow in my own plot.
The growth has been good in the past two months. I estimate that in another month, we will be able to see full ears of wheat.
I have a few pounds of seeds here, would you like to take them back and try them?"
Li Yang smiled knowingly, took the seeds from Sun Delin, and nodded, "Okay, I was just worried about where to try planting. With these, I will find a piece of land and plant them myself, and think about it carefully."
The two chatted for a while, and Li Yang asked Sun Delin to record the growth of rice and wheat in detail and organize the data regularly for future reference by the Academy of Agricultural Sciences.
Sun Delin agreed one by one and thanked him repeatedly.
After seeing Sun Delin off, Li Yang strolled along the ridge of the field, gazing at the green ocean for a long time, and was somewhat absent-minded for a moment.
He recalled the era before he traveled through time, when hybrid rice and wheat were already very common, and not at all as exciting and thrilling as they are now.
Farmers at that time no longer had to worry about having enough to eat. They only had to work hard and they would get a good harvest every year.
The advancement of science and technology has not only changed the yield of crops, but also changed the fate of millions of farmers.
And now, when Li Yang stands on this green field and looks at the changes that have taken place because of him, he feels a sense of mission and responsibility.
……
After returning to the United Technology Center, Li Yang went straight to the office and immediately plunged into a new round of research and development work.
At this moment, he was extremely excited.
With the birth of "Dongfang No. 1", a new plan is gradually taking shape in his mind - machine tool upgrade project.
That’s right. If the birth of the first generation of CNC machine tools brought epoch-making progress to mechanical manufacturing, then the second generation of intelligent machine tools supported by integrated circuit technology will lead the industry into a new era!
You should know that current CNC machining still mainly relies on punched paper tape, which has cumbersome programming, poor reliability, and is difficult to adapt to the flexible manufacturing needs of complex workpieces.
But if the third generation of computer chips are used, the situation will be very different.
First of all, the high-speed computing capability of the chip can greatly improve the execution efficiency of CNC instructions and achieve more accurate and faster interpolation control.
Secondly, the chip can also integrate more logical functions to realize the modular design of the CNC system, greatly simplifying the system architecture.
The most important thing is that with chips, CNC machine tools can truly become "intelligent".
For example, advanced functions such as adaptive control, fault diagnosis, and remote monitoring will become possible.
The machine tool is no longer just a cold "lump of iron", but an intelligent "production unit" that can autonomously adjust parameters, optimize processes and improve efficiency according to processing requirements.
This will be a revolutionary breakthrough in the field of machine tools!
When Li Yang thought of this, he couldn't hold back his excitement. Yes, with the support of chips, the machine tool upgrade is just around the corner!
You know, the reason why his previous generation chose relays and contactors as CNC units was to prepare for this day.
Nowadays, you only need to insert the chip into the reserved slot and slightly modify the interface circuit to achieve a comprehensive intelligent upgrade!
Thinking of this, Li Yang couldn't wait to pick up the drawings and pen and started the intensive design work.
He first sketched out a brand new system framework on the drawing: it consists of several major modules such as control unit, servo drive, sensor feedback, etc. Each module is interconnected by a bus to form an organic whole.
Then, Li Yang began to design the core control unit.
He decided to adopt a modular structure and integrate various functional circuits in the form of plug-in cards.
The most critical ones are the operation control card and memory card.
For the computing control card, Li Yang chose his most proud custom chip.
It integrates multiple functions such as 8-bit CPU, dual-port RAM, programmable logic controller, etc., with a computing speed of up to one million instructions per second, and can easily cope with the real-time control requirements of complex workpieces.
The memory card uses an SRAM chip with a capacity of up to 256K, which can store thousands of lines of CNC programs, as well as various compensation parameters and tool library information.
In addition, Li Yang also designed special servo interface cards, sensor interface cards, etc. to achieve motion control and process monitoring.
The drawings were completed quickly. Li Yang looked at the pages of design drafts and felt full of confidence.
With this new "chip brain", is the new generation of intelligent machine tools far away?
Next, the most critical hardware transformation comes.
Li Yang convened the technical center's mechanical experts and electrical engineers to explain the upgrade plan step by step.
Everyone was fascinated by what they heard, and they were all rubbing their hands, eager to try it out.
Soon, under the command of Li Yang, a vigorous intelligent transformation was launched in the workshop.
The technicians put on dust-free suits and carefully removed the machine tool guard plates to reveal the control cabinet inside.
Opening the cabinet door, rows of relays and contactors are clearly visible, black in color and exuding a sense of age.
"Come on, take all of these apart and replace them with new control units." Li Yang commanded.
Everyone nodded and started to dismantle the old components.
The contactors made a crackling sound and the relays fell to the ground with a clanging sound, but were quickly picked up.
Then, the brand new control unit was carefully placed in the cabinet. The workers inserted various function cards one by one, turned on the power, and the system's LED indicator flashed a cheerful green light.
"Wow, it's so exquisite and different!" someone exclaimed.
"Don't be impatient, it's not over yet." Li Yang smiled slightly, opened the electrical schematic, and began to deploy the peripheral circuit transformation.
"Connect the limit switch signal here to port 2 of the IO card, and the A and B phases of the encoder to ports 5 and 6. As for the tool magazine and tool setting instrument, the signal line can be directly connected to the dedicated tool card..."
Under Li Yang's guidance, the renovation work was carried out in an orderly manner. In a blink of an eye, each machine tool was completely renewed, both inside and outside.
Even the outer shell of the machine tool has been repainted with a silver-gray paint that symbolizes the future, shining brightly under the fluorescent light.
Finally, when the last signal line was welded and the last function card was inserted into place, a brand new intelligent CNC machine tool appeared before everyone.
Li Yang couldn't wait to walk to the machine tool and gently pressed the start button.
In an instant, with a "hum" sound, the spindle motor started to turn happily, and the smooth desktop moved in response, starting the first dry run.
Li Yang stared at the display screen hanging on the machine tool and saw the numbers on it jumping rapidly, constantly refreshing the real-time status of the machine tool.
Spindle speed, feed speed, tool number...a series of parameters are clearly displayed on the screen.
Li Yang tried to input a program on the keyboard, and saw that the machine tool immediately began automatic processing. The tip of the tool deftly shuttled back and forth on the workpiece, cutting off a string of spiral metal chips.
Everyone was fascinated by the show. For a moment, the workshop was silent as everyone was concentrating on appreciating this "technological feast".
"Success! We succeeded!" I don't know who was the first to shout, and then the whole workshop was in an uproar.
