Through the method of experiment, the cutting force data of various influencing factors are measured, and the expression reflecting the relationship between various factors and cutting force is obtained by processing, which is called the empirical formula of cutting force calculation

In practice, there are two empirical formulas of cutting force: one is exponential formula, the other is unit cutting force. Exponential formula: FC = KC & # 8226; ap• f=kc• hd• bd kc=Fc/A d=Fc/(a p• f)=F c/(b d• h d)

FP -- back force (n)

Ff -- awesome force (N). p>

extended data:

compared with ordinary machine tools, CNC machine tools have the following characteristics: high machining accuracy and stable machining quality; high precision and stable machining quality; It can carry out multi coordinate linkage, and can process complex parts; When the machining parts are changed, generally only the NC program needs to be changed, which can save the proction preparation time

the machine tool itself has high precision and rigidity, and can choose favorable processing amount, with high proctivity (generally 3 ~ 5 times of that of ordinary machine tool); High degree of automation of machine tools can rece labor intensity; The quality of operators is required to be higher, and the technical requirements of maintenance personnel are higher

7. In go, the outcome is determined by the number of intersections. The intersection is the result of the intersection of 19 horizontal lines and 19 vertical lines in the chessboard × 19 = 361 points. In technical terms, these points are called "Mu" or "Zi". The last side with more mesh or sub number wins. But generally speaking, the black side should first paste 7.5 mesh to the white side to balance the advantages of the first hand, that is to say, the white side should add 7.5 mesh to compare with the black side. Note that the meanings of "Mu" and "Zi" are different from those mentioned above. Here, "Mu" and "Zi" refer to two different methods of calculating the outcome. Either method can be used, and the meaning is the same

let's first talk about the calculation method of "item": the difference between the number of items on both sides, such as 180.5 items on the black side and 180.5 items on the white side, is that the white side wins 7.5 items, because the black side has to post 7.5 items first

let's talk about the calculation method of "sub": half of the intersection point is 180.5 + 3 + 3 / 4 (half of 7.5 mesh). If one party wins by more than this number, the number of sub winning is the difference between the number of sub winning party and 180.5 + 3 + 3 / 4, which is the same as the above example, that is, white party wins 3 + 3 / 4.

8. There are many digital currency wallets. Here are some wallets
anmao wallet
anmao wallet is a light wallet developed by Hangzhou anmao blockchain Technology Co., Ltd., which saves storage space compared with full node wallet.

9. Xiaobian introces a usdt wallet with high security factor. The reason why the security factor is very high is that in the decentralized mode, the file or private key of usdt wallet can be stored off the network, for example, it can be backed up in the mobile phone, hard disk, U disk, network disk, or even written on paper with a pen

we often hear that users usually store most of their digital assets in cold wallets, mainly for the sake of security, while a small amount of digital assets are stored in hot wallets of exchanges to facilitate trading. Now most usdt wallets are centralized wallets, and users' digital currencies are stored in exchanges. In other words, they are very insecure, Because you don't know your usdt wallet file and private key, the exchange is attacked by hackers or closed by yourself, you can't do anything but watch your money at his disposal

you can master your usdt wallet file and private key, and your currency will never be lost. When you need to trade, you can import it into the decentralized wallet website or the official PC wallet, and then transfer it to the exchange for trading. This is the safest way to ensure that your currency will not be lost

Xiaobian recommends that you use the ethmm wallet, which is a decentralized wallet. Only when you master the usdt wallet file or private key can you enter the wallet for receiving and sending

ethmm wallet can log in from a variety of platforms, such as Android, iPhone and windows

official website of ethmm Wallet: https://www.ethmm.com/

any of the three unlocking modes of cold wallet is the safest and most reliable
[keystore file]: wallet file + password, which can be received or sent by importing the website supporting decentralized wallet or official PC wallet
[mnemonics]: mnemonics are random words that can be used to unlock your wallet directly. It is suggested to make more copies on paper
[private key]: a private key is a random unique string that can be directly unlocked for receiving or sending. You can write it on paper with a pen<

say important things three times:
remember to save more copies of your usdt wallet file and private key, such as the backup USB flash disk, mobile phone, computer, and the private key written on paper with a pen
remember to save more copies of your usdt wallet file and private key, for example, in the backup USB flash drive, mobile phone and computer, and write the private key on paper with a pen
remember to save more copies of your usdt wallet file and private key, for example, in the backup USB flash drive, mobile phone and computer, and write the private key on paper with a pen< br />


Xiaobian sincerely pushes you to use the cold wallet, so that your coin will always be your own. I repeat, as long as your wallet file and private key are not lost, your coin will never be lost

usdt wallet, usdt cold wallet, usdt official wallet, usdt online wallet, usdt wallet management, usdt wallet security, usdt wallet in charge, usdt wallet setting

eth1 fragmentation design assumes communication with data fragmentation through beacon chain. If the second phase (phase 2) with multiple execution slices is introced later, then this method will be meaningful. Since the current focus is mainly on the rollup centric roadmap, putting Ethereum 1.0 on a dedicated slice (that is, independent of beacon chain) brings unnecessary complexity to the consensus layer, and increases the delay between publishing data on the slice and accessing them in eth1

we propose to eliminate this complexity by embedding eth1 data (transaction, status root, etc.) into beacon blocks and forcing beacon chain proposer to generate executable eth1 data. This would make eth1 implementation and effectiveness a first-class citizen of consensus.
