"Don't worry about the mine temperature for now, there is another matter." Tao Decai said to Duan Zhu.
Duan Zhu said: "What else can you do?"
Tao Decai said: "We need to speed up the construction. See if you can come up with any solution."
Duan Zhu said that he would talk to his two friends.
Duan Zhu said: "Now we can no longer use gravity stones to process parts, we have to use the original technology."
Sun Shiji said: "Original technology? Our current technical level is not high, how can we develop new technologies?"
Wu Tian said: "What technologies can speed up manufacturing?"
Duan Zhu said: "For example, using multi-degree-of-freedom machine tools and using multiple sets of tools."
"The machining factory is willing to assist us. They can provide equipment for manufacturing CNC machine tools. However, the CNC machine tools originally used have been used for a long time and are relatively reliable, so they have not developed new equipment. If needed for the construction of the new city, some can be designed and manufactured."
Wu Tian said: "What about the CNC systems we originally designed? Can they be used? That means using computers to replace computer CNC devices, and programming on the computer to convert them into CNC language."
Duan Zhu said: "Okay, let's give it a try. Let's go to the machining factory."
Tao Decai saw them coming and went out to greet them. "Nice to meet you. Come here. Do you have any new ideas?"
Duan Zhu said: "We plan to design a multi-angle processing equipment. We need you to provide some materials."
Tao Decai said: "How about the multi-angle method?"
Duan Zhu said: "It is to use multiple cutting tools and multiple robotic arms to perform multi-process processing from multiple angles at the same time to shorten the time."
Wu Tian said: "Why is it so urgent this time? It takes so little time to build the new city?"
Tao Decai said: "Now it is found that the content of pillar ore is gradually decreasing. It has exceeded the mining speed."
"I heard that the pillar ore in the Licheng mine is mobile. After a while, the pillar ore will flow to other places."
Wu Tian said: "Ah, has this pillar mine become refined? Can it still run?"
Tao Decai said: "It has something to do with the movement of the earth's crust. The upward movement of the earth's crust brings the minerals closer to the ground. The downward movement of the earth's crust brings the minerals to deeper places. The parallel movement of the earth's crust brings the minerals farther away from the city. place."
Wu Tian said: "This movement is too fast."
Tao Decai said: "It may be for other reasons. Now we need to build the urban core first, which includes the raw material handling system, processing system, and construction system. It is used to build other buildings, roads, and bridges. I heard that the company responsible for the construction of the urban core There are internal differences. If it cannot be constructed within a short period of time, the building cannot be delivered for use, and there is no way to make a profit. Some say that construction should be stable, some say that construction should be accelerated, and some say that green construction concepts should be followed."
Duan Zhu said: "In fact, our method of accelerating construction also follows the concept of green construction. It is manufactured in parallel and saves materials."
Tao Decai said: "How to do parallel manufacturing?"
Duan Zhu said: "Blanks 1, 2, and 3 can make multiple parts, instead of making one part from one blank as before. These blanks are planned first, and the shapes of multiple parts are placed in the computer software. A is large in size. , in the volume of BC, the volume of D is small, the volume of blank 1 is relatively large, the volume of blank 2 is smaller, and the volume of blank 3 is the smallest. Then blank 1 is put into the shape of part ABC, blank 2 is put into the shape of part ABD, and blank 3 Put the shape of part BC. Or there are more types of blanks, blank 1 is the largest, and blank 5 is the smallest. Blank 1 is put into the shape of part ABCD, blank 2 is put into the shape of part ABC, blank 3 is put into the shape of part ABD, and blank 4 is put into the shape of part ABCD. Put the shape of the part BCD, and put the blank 5 into the shape of the part BD.”
In short, according to the volume of the existing blanks and the volume of the parts that need to be made, which blanks are used to make which parts.
It's like having the same number of boxes. You can place many parts. If you place them in one way, some boxes will be relatively empty. Then use another way to place it. You can use one less box and put all the parts in the box. At this time, the space of each box is fully utilized.
The same goes for selecting the blank corresponding to the part, that is, you can use a blank early, so that the material of each blank is fully utilized.
Carry out turning processing. The scraps around the cylinder or cuboid can be used.
For milling processing, the leftover materials around the flat plate blank can be used.
When processing three-dimensional parts, the scraps around the cuboid and the scraps inside can also be used to process other parts at the same time.
However, there are many issues to consider when using tools. For example, when turning is performed, the entire blank is rotating. It turns out that for milling and drilling, the entire blank is fixed on the workbench. When milling and drilling at the same time, the two tools cannot touch each other when entering and retracting.
When multiple tools are performing rotational processing, their angular velocities must be basically equal and they must not touch each other front or back.
When processing small parts, other parts must be processed first, and finally separated from the large blank. Otherwise, if you cut it off directly, there will be no way to fix it. Before cutting off, it must be grasped by a robot hand and placed in a fixed position. Large parts can be processed on the original workbench and placed on the workbench after processing.
Wu Tian said: "In the future, there will be a three-dimensional printer, which uses a tool and a laser to scan over it, and the three-dimensional part will come out. It is different from a 3D printer. A 3D printer is a cumulative manufacturing technology, that is, rapid prototyping technology. A machine that is based on a digital model file and uses adhesive materials such as special wax, powdered metal or plastic to create three-dimensional objects by printing layers of adhesive materials. Currently, three-dimensional printers are used To make products. Technology that constructs objects by printing them layer by layer.”
Some 3D printers use the "inkjet" method. A very thin layer of the liquid plastic substance is sprayed onto the mold tray using a printer nozzle. This coating is then exposed to ultraviolet light. Some systems use "fusion deposition molding" technology, where the plastic is melted in a nozzle and then deposited into a thin layer of plastic fibers. Some systems use a technology called "laser sintering" to use powder particles as the printing media. Powder particles are sprayed onto the mold tray to form an extremely thin layer of powder, melted into the desired shape, and then solidified by the sprayed liquid adhesive. In some systems, the electron flow in the vacuum melts powder particles. When encountering complex structures including holes and cantilevers, gelling agents or other substances need to be added to the medium to provide support or occupy space.
Wu Tian said: "The three-dimensional printer I am talking about still uses a variety of cutting tools and lasers to perform rapid scanning processing."
Tao Decai said: "Then how to process the middle part of this part?"
Wu Tian said: "This reminds me of the gravity stone. The light it guides seems to be intermittent. So is it possible to make the laser disappear at a certain point and appear at a later point to cut and process the middle part."
Tao Decai said: "That was a system that was studied a long time ago. At present, we are using this idea to improve the multi-axis CNC system of the processing plant."
They seized the time to improve the CNC system and manufacture the prefabricated building body and a large number of bolts and nuts.
