The Chinese government will not force the implantation of chips

< UL >

the chip has special functions, such as detecting blood conditions, and it will be linked to the hospital and your personal files, so satellite positioning must be indispensable

implantable chips are mainly used in medical treatment

Professor Li Bin of School of electronics and information of South China University of technology has been engaged in the research of implantable chips for many years. She believes that implantable chips are mainly used in medical treatment and may have great value for some diseases“ For paralytic patients, the implantable chip plays a role in replacing the damaged nervous system. It first records the signals sent by the brain, and simulates the generation of nerve signals, so as to stimulate the lower nerves, so that the paralytic patients can control limb activities and stand up again. " Li Bin said that although the implanted chip has not entered clinical trials, it is a major research hotspot and the most significant development direction

in addition to medical treatment, there is still a lot of room for the development of embedded chips. For example, the police can use microchips to track criminals, locate fugitives, witnesses and missing persons. If the alarm function is loaded on the chip, once the monitored object enters the restricted floor, the alarm system will be triggered, and this function can be applied to prevent illegal immigration

in the financial field, once the chip is swiped, payment can be made easily. If personal data, such as passport information, is put in it, travel will become easier

Cam is computer aided manufacturing. Up to now, cam has two concepts: narrow sense and broad sense

The original narrow concept of cam refers to all proction preparation activities from proct design to manufacturing, including CAPP, NC programming, calculation of man hour quota, formulation of proction plan, formulation of resource demand plan, etc

However, today, the narrow concept of cam is even further reced to numerical control technology, that is, the technology of using computer to control the action of machine tools in the form of digital instructions, that is, numerical control programming

Background: the 21st century is a period of rapid development and wide application of information technology, and advanced manufacturing technology has become the guarantee for the development of manufacturing instry. CAM technology originated in the developed countries in the 1960s

Moreover, the development of CAM technology has always been closely linked with CAD technology, because CAM technology directly uses CAD data information to realize NC programming. Now CAM technology has become the core foundation of advanced manufacturing instry, and its development and application has become an important symbol to measure the progress of an enterprise and instrial modernization

extended data

Application of cam:

before the popularization of CAM technology, programmers can only program manually, and then determine whether their own programming is safe and effective through field operation. Programmers need to go through various steps such as part drawing analysis, process plan, numerical calculation, programming sheet to program verification to complete the programming

manual programming can only be used when the shape of the part is simple and the machining program is short. Once the shape of the part is complex, such as the part with non-circular curve, list curve and composite surface, or the part with complex shape and long machining program

at this time, the working efficiency of programmers in the process of manual programming will become lower, and compared with automatic programming, it is easy to make mistakes, and even crash events will occur, resulting in incalculable losses

With the rapid development of modern instry, CAM technology has been widely used in aircraft, automobile, machinery manufacturing, household appliances and electronic procts manufacturing

especially with the increasingly high precision requirements and complex shapes of parts in the automotive and aerospace instries, the traditional design and manufacturing methods can not meet the current requirements, so NC milling becomes more and more important. Before NC milling, the application of CAM technology has become an indispensable link

4. The core of cam (computer
aided
manufacturing) is computer numerical control, which is a process or system that applies computer to manufacturing process
in different instries, the direction may be different. It may be a software, a file or a system.

5. The abbreviation of computer aided manufacturing.

6. Right

7.

Computer aided manufacturing (CAM) is to convert the results of CAD system into the control instructions and data that can be accepted by the processing machinery, and to manufacture the procts

The main functions of cam system are design data conversion, computer-controlled CNC machine tools, computer-aided manufacturing process planning, processing time arrangement, tool design and proction process, automatic mold manufacturing, automatic material processing, automatic assembly and machine management, etc

9. If you go to the confinement center with your own money, you can say that for the sake of your mother-in-law's health, you can spend her old age in peace. When her mother-in-law is old, she will worry less and work less. If you go to the confinement center by yourself, your mother-in-law won't have to work so hard. She will be happy and relaxed to be a grandmother

10. There is no issuing agency for bitcoin, and there is an issuing and operating team for all digital currencies except bitcoin. For example, Ruitai coin, thousand gold card and Yuanbao coin. The information of the development, operation and maintenance teams is open and transparent. Without the issuance team, you can't play with bitcoin, because bitcoin has passed the test of the market.
