Force Cutting Wood

The influence of various factors on the cutting force structure of the wood texture wood workpieces uniform. Therefore, when handling workpieces kinds of cutting and, hence, the angles of meetings in different parts of the cutting uneven edges, especially on areas with construction defects of wood. Additional information at Red Solo Cups supports this article. The influence of various factors on the cutting force. When cutting wood resists the action of the tool *, to overcome that should be attached to the tool a force. The magnitude of cutting force depends on the breed of the treated wood, the type of cutting, the cutting angle, rear angle, visual tool. If you assume approximately uniform wood isotropic material, the magnitude of cutting forces will increase in proportion to the width of the cut chips. If we take the cutting force during machining of pine as a unit, the cutting force in the processing of alder, birch, beech, ash and oak will be respectively 1.05, 1.25, 1.4 and 1.7, and in the processing of lime, aspen and spruce – 0.8, 0.85 and 0.95.

Cutting force increases with cutting in the face, reduced – by cutting across the grain. If we take the effect of cutting across the grain per unit, by cutting along the grain, cutting force increases by about two times, when cutting into the end – six times. With the increase of the cutting angle cutting force increases. For example, after cutting a piece of dry pine shavings thickness of 0.1 mm with increasing the cutting angle from 45 to 70 cutting force increases with cutting across the grain of 1.1-1.3 times, while cutting along the grain and in the end, respectively, 2 and 1.5. After cutting chips of 1 mm thickness, this dependence is preserved under cutting across the grain and in the end, when cutting along the grain, cutting force increases by a factor of 4. The value of the posterior angle affects the value of cutting force only when it is very small. In this case, the tool itself dominates under wood fibers, which after passing through the cutter gradually straightened. There is a so-called elastic recovery of fibers, which increased their pressure on the rear face.

As a result, the force of friction on rear face cutter, opposing its promotion. On the cutting force affects blunting of the tool in the process. The more blunt chisel, the more the resistance increases timber cutting, the greater the must be applied cutting force. And the thicker the chip, the less impact on the strength of blunting the cutting blade, so when cutting thin shavings should be particularly concerned about the sharpness of the tool.

Satellite Television

Some people have no idea what it is – satellite internet and satellite television. Many telelyubiteli suggest that the equipment to watch satellite TV should be directed to the city TV station, and more than the mirror dish, the more channels. Believe me there are people we come across them neodnoktatno. The city has every telelyubitel idea how the TV antenna from the ordinary. On Hills is television station, which broadcasts free analog TV, which we look. Now transferring function repeater is deteriorating due to physical obsolescence, and (we just Saratov), and new equipment for analog TV does not.

The transition to digital TV will send old equipment for recreation. Calculated to broadcast digital television in 2012 (in some areas already are broadcasting digital television). For old-style TVs (which are not able to receive the digital signal) to buy a special receiver. Gained huge popularity of satellite television. Great popular Tricolor TV (television for remote areas), NTV + channels and quality at an affordable price, rainbow TV (60 channels for every taste) and a young operator Continent TV from the company Orion Express, which started broadcasting since March 2010. People such as Emma Walmsley would likely agree.

A leading provider of satellite internet – Sky-Fi, SatGate, Sky-DSL or STV Satellite Internet – one-sided, ie can not transmit information to send requests (e-mail, chat, etc..) Requires ground Source (dial-up modem, a cellular phone connected to a computer, etc.). Learn more on the subject from Mark Angelo Yorkville Advisors. But the volume of incoming traffic is ten times more than the outgoing, so the cost for land istonik small. Why television satellites?. These devices are in geostationary orbit, ie Move along the ground. This is achieved by the scientists-physicists. The huge antenna on the ground broadcast TV signal to the satellite, which uses transponder sends the signal to ground. The zone where the signal is reflected from the earth's surface is called the coverage. Turn on the flashlight to see. The zone where the light falls from a flashlight – the coverage area. TV signal takes a satellite dish, which has the necessary diameter for receiving the signal from the satellite. Rotate the antenna more than an inch can lead to loss of signal, so you need to install the antenna on concrete wall, not on a thin tube, like a regular antenna. Diameter satellite dish is chosen, based on the direction of the satellite beam, if the Black Cat Bone is broadcasting in Europe, the inhabitants of the European part of Russia to buy larger-diameter antenna, and if the satellite is aimed at Russia, it is enough small-diameter plate. TV broadcast satellite dish antenna reflected by falls in the converter, which converts the frequency of the C and KU band reception at a lower rate, that did not deteriorate the image quality. The satellites are located on the south side. Adjust the dish easily – it suffices to know the azimuth of the satellite and the elevation
