——It's not that Yang Weiping's psychological quality is not good, but that he will be fixed at a historic moment and forever in the history of the development of Huaxia machine tool industry!

CNC machine tools, especially multi-axis CNC machine tools, the core technology is CNC program.

The five-axis linkage CNC machine tool has the characteristics of high efficiency and high precision, and the workpiece can be clamped once to complete the processing of pentahedron. If it is equipped with a high-end CNC system with five-axis linkage, it can also carry out high-precision machining of complex space surfaces, and can be more suitable for the processing of modern molds such as auto parts and aircraft structural parts.

The hardware of the machine tool, many countries can copy it. But the program software can't be copied anymore.

Since the ASCII code was invented by the Americans, the numerical control program of the single-chip microcomputer is based on this British universal code table for various programming.

Now, Pan Yaotian has ingenuity to propose the use of Yongzi eight methods, with the assistance of Wu Hook and the strong support of Yang Weiping, he has created the GB1978 Chinese character universal code table, which marks the future development of the world computer will no longer be dominated by the Americans.

Whether the numerical control program programmed with GB1978 code can be practical, now, as long as Yang Weiping gently presses the index finger of his right hand, it will be revealed.

"Director, Director Yang, I have full confidence in the program we have made up!" Wu Hook clenched his fist with his right hand on the side, cheering Yang Weiping up.

Yang Weiping took a deep breath, his gums clenched tightly, and he gently pressed the green power start button.

"Hum", the motor rotates, and the sound is directed in response.

Now everyone was silent at this moment, and their eyes were locked on the display screen of the program control page.

0，10%，30%，…… 100%, the number does not move the beat, and the program self-test is completed.

X-axis motor drive: normal!Servo module working: normal!

Y-axis motor drive: normal!Servo module working: normal!

Z-axis motor drive: normal!Servo module working: normal!

The A axis rotates around the X axis +90~-90, and the minimum score is 0.001: normal!

The C-axis rotates 360 around the Z-axis, and the minimum score is 0.001: Normal!

Residual Regulation: Seven. Normal!

This is a gantry milling machine that relies on the rotation of the vertical spindle head. The front end of the spindle is a rotary head, which can surround the Z-axis 360 by itself and become the C-axis, and there is also a A-axis on the rotary head that can rotate around the X-axis, which can generally reach more than ±90, to achieve the same function as above.

The advantage of this setup is that the spindle machining is very flexible. The workbench can also be designed to be very large. The huge fuselage of the propeller and the huge engine casing can be machined on this type of machining center.

This design also has a big advantage: when using the spherical milling cutter to process the curved surface, when the tool center line is perpendicular to the machining surface, because the vertex linear velocity of the spherical milling cutter is zero, the surface quality of the workpiece cut out by the vertex will be very poor, the design of the spindle rotation is adopted, the spindle is rotated at an angle relative to the workpiece, the spherical milling cutter is made to avoid the vertex cutting, and a certain linear speed is guaranteed, and the surface processing quality can be improved.

Everything is running normally with the empty aircraft. Yang Weiping's right hand bent his elbow and clenched his fist, holding back the excitement in his heart and not shouting.

This proves that the newly written set of Chinese character coding numerical control programs, software and hardware have been compatible.

Next, it depends on whether there will be any unknowable faults in the actual machining process.

In order to verify the high finishing capacity of this imitation and improvement, the tentative model number of the five-axis linkage CNC machine is SK1978-5-7. Yang Weiping deliberately chose a cambered cam for the machined parts.

Its parameters are center distance, fraction 8, dynamic and static ratio 135°/225°, left-handed, groove depth 48mm, roll diameter 90mm, snail arc radius. The cam is wide.

The cam is processed on a special five-coordinate machine tool, because the cam center distance is, greater than the maximum adjustable range of the machine tool 40~, so it can not be directly processed.

Other than that. When the center distance of the machine tool is adjusted to be greater than, due to the characteristics of the structure, the length of the tool to the end face of the spindle will be greater, and the length of the spindle overhang will be greater, and the machine tool spindle will be significantly worse, and the machining vibration will be too large, which is very unfavorable to the machining.

However, this is for general CNC programs.

Now, through the application of this more than seven numerical control programs, Yang Weiping has re-selected a new calculation formula, set up a special automatic programming program for cam machining, and added compensation margins to the X-axis and Z-axis.

The conversion of coordinates can be automatically realized, and the transformation does not affect the functions of tool support algorithm, eccentric algorithm, feed rate correction, cam surface modification and calculation error control in the original program system.

The actual cutting results show that this set of numerical control programs expands the original processing range of the machine tool, so that the center distance parameter range of the original design of the machine tool is expanded from 40 ~ to almost unrestricted and only related to the motion interference of the machine tool.

Through the flexible application of numerical control programs, the machining parameters can also be adjusted to improve the rigidity and machining efficiency of the machine tool.

In the machining of this calibrated cam, the spindle overhang was shortened by 80 mm due to the selection of a different center distance of the machine, resulting in a reduction in machining time of nearly 30 percent and a one-level improvement in the machined surface quality. As a result, the functions of the machine can be expanded and the use is more flexible.

The old eighth-level technicians who watched at the scene witnessed the camber cam being automatically processed from the blank, and the whole process basically did not require manual operation.

In particular, there was an old technician who personally used a tool microscope to inspect and announced that the arc surface processing was fine, and these old eighth-level technicians could no longer hold back the shock in their hearts.

"It's a trick!"

"It's amazing! The five-axis machine is amazing!"

"I've seen it for a long time! I've seen it for a long time! I've really lived to be old!"

Without Director Yang, there would be no five-axis linkage CNC machine tool, let alone a Chinese character coding CNC program that belongs to our unique Huaxia!"

"It's a success! Director Yang, we've succeeded!" Pan Yaotian held the incomparably smooth cam in both hands, and held it in front of Yang Weiping, who was standing there in a daze, shaking again and again.

"Quack, quack, quack, I know that the program I wrote will definitely pass the test in one go!" Wu Gou laughed excitedly.

"It's done, it's really done, and the essence is up to standard?" Yang Weiping obviously didn't believe the facts in front of him, he stared at the curved cam Cheng in Pan Yaotian's hand with his eyes, and asked in a trembling voice.

"It's done!" Pan Yaotian nodded vigorously and replied happily: "It's perfect, more powerful and more advanced than SK1968! The operation is easier than Toshiba Machine's MF4522, and it's fine!"

Yang Weiping's eyes became fanatical, and he shouted loudly: "We Chinese people can also formulate new standards for us in the CNC machine tool industry! The blockade and monopoly of European and American countries to control CNC technology will be gone forever! The diligence and wisdom of the great Chinese nation are invincible!"

"Long live the great Chinese nation!" Wu Gou shouted feverishly.

"Long live the great Chinese nation!"

"Long live the great Chinese nation!"

"Long live the great Chinese nation!"

Everyone at the scene, regardless of gender, old and young, all raised their arms and shouted excitedly!

Yang Weiping also couldn't help but cheer with the crowd, compared with nickel-based single crystal alloys, the high-end CNC programs independently developed by Huaxia people undoubtedly made him ecstatic and excited. This means that Huaxia's basic industry will enter a new level from now on!

Single-crystal alloy is only the material that solves the advanced aero engine, while multi-axis CNC technology can cover all basic industrial manufacturing and processing fields.

You can imagine that when all industrial enterprises in China have used precision CNC machine tools, with the professional quality of more than 100 million industrial workers in China, the huge production capacity of China's industrial system will definitely make the entire world be shocked!

All the high-tech and advanced equipment in the world today can be copied and improved in China! The so-called Batumi embargo clause has since become a piece of waste paper!

The machine tool industry is the foundation of all industries in a country, even if it is the best material, precision machining is not good, and it still cannot play the excellent performance of this material.

Now, Yang Weiping has not only made the first five-axis linkage CNC large-scale gantry milling machine in China, but more importantly, this is a set of more than seven high-end CNC programs coded in Chinese characters. The overcoming of this problem means that all the worries in Yang Weiping's heart no longer exist, and he no longer worries about what tricks and tricks the United States and the Soviet Union are playing behind his back!

With the GB1978 Chinese character code, which can replace the ASCII code, Huaxia can use the wisdom of the Chinese people to design a variety of unique computer programs.

The future world will be the computer network information age. Whether it is computer software or various hardware chips, it is inseparable from programming.

Although the current set of CNC programs developed is only the simplest eight-digit binary, with this foundation, octal, decimal, and hexadecimal conversion is no longer a problem at all.

And more importantly, through this CNC programming, it is confirmed that the GB1978 code can be compiled into a computer language for use. The significance and benefit of this for the popularization of computer education in China in the future cannot be measured by monetary value.

The use of the computer language of the Chinese people by the Chinese people is also of immeasurable significance to the expansion of the influence of the Chinese people on a global scale. ______________________
