Immediately decoding the concept of 'NC': Numerical Control Software. CNC is the different types of machines (milling and engraving, drilling, milling, laser, cutting, and many others), oborudovannnye system program management. Automation system for production machines was held, tentatively, in two stages. At the initial stage of automatic processing machines were equipped with type NC. Technological process control machine was carried out thanks to the program specified by the connectors and switches. Kept this program on punch cards and magnetic tapes. The next stage – the introduction of microprocessors and operating systems memory.

At this stage, it became possible to download the program, for example, for milling machines with removable media – floppy disks, 'Sticks'. In addition, increased automation – equipment connects to the communication system of the enterprise. The main programming language document describes CNC ISO 6983 International Standards Committee. In some cases, program management can be a text file format data (for simple). CNC machines have a number of advantages. First, the most obvious advantage – it is actually very automation. Ie people do not go and does not follow the process and does not produce adjustment.

In addition there is one of the causes of errors in the production – the so-called human factor. Next: as milling machines or any other managed program, the possibility of error is eliminated. Various errors in processing occur only in the event of errors in programming or configuration. CNC machines are faster than manually operated. Thus the volume of production increases are not at the expense of quality. Taking into account all the above material, we can conclude that the machines – 'this is good'. CNC machines allow you to increase the effectiveness of any proceeding, whether metal or construction of billboards.

Writing tutorials and video lessons noble occupation. Nowadays, digital video tutorials, or "video tutorials" are popular with many. We can say that almost every family has computers, and many appeared fairly fast Internet connection. And thanks to a demand for educational materials in a standard hard copy and digital. However, if in the big cities the necessary books or CDs can be buy something in the depths of a just and no more will not be long. That is why there was such a movement from private individuals. I am sure that this is only the beginning and it may soon be training videos will be very much in network.

That's why now booming video training online. And everything just want to make a video of their lessons. But in this form of earnings there are many pitfalls. One of the largest stone is undeveloped payment systems to pay for onlay. Of course if you live in a big city, you will not be easy to transfer money into the system WebMoney and make for yourself a virtual wallet. But here are your potential customers may not always boast of such a possibility.

The second of at least a small caveat is that your customers still do not believe in the purity of your intentions and suspect that this is another internet scam. The Internet is certainly very much every kind of deception and novice Internet users still can not distinguish between fraud. To gain the confidence of the customers need to periodically record the free training video tutorials. Customers see it and appreciate the quality of your free lessons and if they want to buy a video course, then they will have a general idea of your lessons. In other words, buyers will not buy a pig in a poke. In my opinion any qualitative Training material may not be free, since it is still a certain author's work, which perhaps is not done in one day. And as you know – all work must be paid. At this point in the network laid out a lot of video Lessons on various topics. This video graphic arts and learning to play the guitar and even recipes on the video record and sell. But what of the quality of these products is very difficult to determine. To determine the quality can be a search. For example, typing in any search engine 'reviews of video course' of course you need to write the name of the video course. Usually on a specific topic forums discuss these or other classes and courses. After determining the product quality or, rather, the analysis of feedback, you can once again look closely at free lessons by this author. And I'm sure you will get a proper impression of the author and his product. But it may be advisable for authors make a few quality free videos and add these lessons to various websites. In a network to promote its product has special sites where anyone can register and add your material for publication. Visitors to these sites looking or reading your lesson can always go to the website of the author and get acquainted with your other lessons. And finally, wished him success in learning and mastering new programs.

Principles Transmission

Modern cars have become so complex, and automatic transmissions are so reliable that the automatic transmission performs the most popular, or even the base version korobkm gear on many models. Over 85% modern cars are equipped with different brands of automatic transmissions. All that is required from the driver – is start the engine, select and operate the gas and brake. Maybe it's not so fun, how to change gears manually, but it is much more effective if you carry heavy loads or pulling a trailer. At the same time, there is a lot of garages that serve them, so that the repair of automatic transmissions in St.

Petersburg, for example, is not a problem. Automatic transmission involves possible engine and includes the transfer, depending on various input data (frequency of rotation the crankshaft speed, throttle position, etc.) to support effective application of torque. Actions normally performed by clutch and manual transmission are performed automatically, using a torque converter, which allows small, controlled slippage between the engine and transmission car. Small hydraulic valves control the inclusion of different gear ratios on the driver's commands (throttle position), or the terms 'hard-wired' response to the current condition of the engine and speed. How does the automatic transmission. Automatic transmission transmits the torque and engine power to the drive wheels in a narrow range of engine speed. Automatic transmission allows the engine to rotate at sufficient speed to generate enough power and torque when the vehicle travels at very slow speeds.

A high speed car automatic transmission keeps the engine rotation reasonable values for it. Automatic transmission fluid is used as the medium for transmission of torque wheels. This gear oil also sends commands to the hydraulic control circuit and acts as a lubricant. Because the transmission fluid performs all three functions, the problems in the box machine can easily spread from one unit to another, making it difficult to repair automatic transmissions. Automatic transmission works on the principle that fluid can not be compressed, and that any body placed in a moving fluid also begins to move under its influence. To realize this law fluids, imagine two ventilyatoroa placed opposite each other. If the first fan is turned on, it begins to rotate the fan blades standing naprotiv.Etot principle is used in the fluid coupling and torque converter with the help of master and slave rotors instead of fans. Each automatic transmission consists of two sections. The front part is a fluid coupling or torque converter and provides an analog clutch, activated by the driver. The rear section avtomaticheskok box contains a block valves and planetary sleeve with hydraulic control, which take the place of a manual transmission. The system locks the brake pedal. For security purposes, a number of cars automatic transmission will not allow the driver to move Automatic transmission lever position 'Drive' or have a car until he presses the brake pedal. This system is usually controlled by the cable from the brake pedal to the automatic transmission or a computer and sensor box machine. On some vehicles You can hear when you click – the sound of the sensor. Very often, this feature protects and repairs of automatic transmissions.
