225 Questions are like sweet potatoes in the field
When Polu stood in front of the blackboard and explained the cylinder to everyone, Trika was still a little disapproving when she faced the round frame with a complex deep pit structure under the ground. She thought to herself:
"It's just such a round frame tube with a pit in the ground. What's so difficult about it? To put it so carefully, what is the most difficult large-scale machinery so far? As for it? Such large cargo ships, mining machines and tractors have all been built.
, what’s so difficult about such a framework?”
She kept her opinion in her heart and quietly looked at the several principles Bolu was emphasizing.
"The most important point is not only how to draw this thing, but it is not enough to be able to operate it theoretically. You must also consider how this thing will be implemented! For example, what materials should be used for this data, what shape can be realized, and how to leave enough
The design margin, the actual damage strength must be 50% greater than the design strength! At least! Then how to produce, how to install, how to maintain, can it be simpler!"
Polu stressed desperately, trying to strangle the castles in the air and the German-style design ideas of greed for bigness and perfection in his mind.
"Everything should at least have a rough idea or step, just write it down on the drawing!"
Caroline circulated the numbered sketches along the way. She came to Trika and handed her a piece of scratch paper with a circle drawn on it and several data scrawled on the side.
Trika took the sketch and just glanced at it, the corners of her eyes twitched involuntarily!
"This, this data!"
Only then did she realize that her voice was too loud and she became the focus of the audience in the quiet space. She suddenly panicked and was about to apologize when she heard Polu ask her: "Is there something wrong?"
Trika felt bitter in her heart - no matter what, pointing out her boss's mistakes in public might lead to tragedy in the future, but under the gaze of so many people, her mind went blank and she really couldn't think of a perfunctory reason.
She had no choice but to ask: "Judging from this data, this thing is as big as a three-story building?"
"Yes, this thing is that big."
"So this surrounding rack is also that big?"
"That's right."
Bolu's decisive answer made her feel like she was hit head-on by a high-speed flying brick.
She regretted it so much now that she almost cried. How to draw this thing and how to realize it? She thought in her heart: "How is this thing simple? I don't even know how to draw so many teeth on the drawing.
Know how to arrange it!”
She lowered her head and looked at the text on the draft paper: "Guaranteed perfect roundness? No tooth loss is allowed during operation? Why is the fracture strength of each tooth so exaggerated?"
At this point, no matter how strong her heart was, she could only lower her head silently: "This part may be a bit too difficult for me. I admit that I may not be able to do it well."
But Polu was not going to give in: "It doesn't matter, you do it first. If there are any problems, we will solve them together during the review. Don't worry about making mistakes. I never ask for the design to be done in one step. The same goes for you, although I have been emphasizing
It’s enforceable, but you can first innovate boldly, and then recycle it step by step! Okay, let’s start each other. I’m always here. If you have any questions, you can ask me.”
Trika sat in front of her experimental table with a straight face. She felt that she was under too much pressure. She didn't know how to determine the number of teeth on the gear, and she didn't know whether to use horizontal teeth or helical teeth, let alone
Knowing how deep and wide the groove should be, she didn't even know how to make such a large hollow steel ring for such a large gear.
"It seems so simple, but why is it so difficult when it comes to manufacturing?"
Her eyes couldn't help but turn a little red.
"Trika, what's wrong with you?"
Alfonso's voice sounded beside her, and she took a breath quickly, turned her head and forced a smile: "I don't know how to make this gear. These requirements...make me don't know how to do it."
"It doesn't matter, let's design one first, and then calculate the torque of the gear. Don't worry, I am the power part that matches your gear, and I will help you."
He smiled gently.
"I first divide the gears into 360 equal parts through the center point. Under this circle diameter, the width of the bottom of each gear is..."
Polu squatted a few steps behind them, secretly listening to the conversation between the two. The young apprentices next to him were holding back their laughter and watching his sneaky movements.
"So considering the tip width of each tooth, we can first assume a center width of 0.5 degrees. As for the involute..."
At this point, Alfonso raised his head and suddenly found that the person opposite him was looking behind him and suppressing a smile. He realized something was wrong, so he quickly turned around and saw the boss and teacher who was crouching behind him and eavesdropping.
A panicked expression suddenly appeared on his face, and he stood up quickly: "I...I was just telling her how to calculate."
At this time Trika also stood up, and she stepped forward bravely with a decisive expression: "I asked him to explain this problem to me. It is all my fault. Please be sure to punish only me."
"Punishment? Why should I punish you?"
On the contrary, Bolu was stunned. He had no idea where this punishment came from.
Trika was also stunned. She once lived in an environment related to mages, and mages were much stricter in their management of apprentices. During the apprenticeship period, only the teacher could impart knowledge. If there was a private exchange of knowledge, there might be consequences.
A range of severe punishments - from confinement to torture and even deprivation of the right to cast spells.
Seeing Trika's nervous look, Polu couldn't help but want to laugh. He waved his hand: "It doesn't matter. I encourage you to discuss and communicate with each other. You will not be punished."
"Really not?"
Trika rubbed her hands and asked cautiously.
"If I say no in front of so many people, can I still be lying? I think his calculation ideas are very clear. It will be no problem to build a scaled-down model first and try it out. Do you have any other questions?"
"Yes, we don't know how to produce this thing."
"Don't you know?"
Polu raised his head and asked the young apprentices around him: "Does any of you know? How to process this thing?"
There was silence.
Polu sighed: "Forget it, stop what you are doing first, let's go to the factory. If you can't figure out how to process it, this design will really not go forward. It just so happens that we have similar work today.
It's going on, let's go take a look."
The first stop was the foundry. Bolu took the young apprentices to a special observation platform. Geola was pouring the thick brackets used by the gantry crane. He waved here from a distance, and Bolu waved his hand.
He went to work by himself, and then explained to the young apprentices: "What is done here is casting... Trikka, your rotor cantilever will be manufactured here."
He turned to the crowd: "And your frame, your shell, your spindle, etc. A lot of our processing starts with casting. Some things with complex shapes will be processed here first. After that, there are
There are finishing processes, heat treatment, inspection and other processes. I can’t finish it at the moment. I will tell you more about how to process it in the future, at least to let you know how a part can be manufactured."
…
During this afternoon, the young apprentices saw the flying steel flowers during pouring, how a large steam hammer kneaded a ball of steel like dough, and how a stamping machine punched out complex-shaped iron products on a production line.
.
Steam! Sparks! Noise! Oil!
The impact of hearing about it and watching it up close were completely different. All this completely shocked these young apprentices who almost only worked peacefully in the precision laboratory. Until they returned to the workshop, they were still immersed in the excitement and excitement
In the scene of the roar of steel, I was still thinking about how to combine the craftsmanship I saw with my own design.
That night, the lights in the workshop of the Precision Institute were on very late.
