The Xbox 360 –a gamer’s dream machine.
The Xbox 360 –a gamer’s dream machine.
The Xbox360 is a video game console that is visionary. It competes with the Sony Play Station 3 and Nintendo Revolution. A gamers’ dream machine, the Xbox 360 is sold in two versions a premium edition that has a hard drive, a wireless controller, headset, Ethernet cable, a HD AV cable, and an Xbox live silver subscription and a core system.
Powerful and futuristic the Xbox360 includes HD gaming, perfect sound, and sensational graphics. The system offers high-end gaming with several exciting possibilities. It revolutionizes video game consoles and is, in actuality, a computer dedicated to gaming. It is not just a gaming machine it is a media center that allows you to play games, network with other gamers around 360 of them, rip, stream, and download high definition movies, music, digital pictures, games, music, and play DVDs and CDs. It is what makes dreams into realities.
The Xbox360 has around 18 titles in the US including games like Call of Duty 2, Dead or Alive 4, Every Party, FIFA 06, NBA live, Kameo, Perfect Dark Zero, and Project Gotham Racing 3. Technically, it has advanced graphics and a 115 GFLOPS theoretical peak performance. All games support a six channel Dolby Digital Sound with no voice echo.
Apart from video and DVD playing the X box 360 live market place allows the user to connect to Xbox live even if offline. Users can view messages and game invites sent by other Xbox live members. The live market place allows download of avatars, trailers, as well as game demos.
With the Xbox360 a person can view a complete record of games played, play games downloaded from marketplace, play game demos, watch movie as well as game trailers, listen to music customized for the user, view pictures as well as videos stored on a camera or any other portable device, and activate the media center extender.
The Xbox 360 has backward compatibility and so, users can play games originally developed for the earlier versions of the box. Wireless connectivity and wireless controllers offer great freedom and connectivity at large distances. And, you can download and play arcade style games using the Xbox Live Arcade. Game demos and trailers are offered free but full versions of games have to be purchased using Xbox Live Marketplace using Microsoft points which can be bought through Live or via game cards sold retail.
Technically a few small glitches have been reported. There is what is known as the Xbox360 screen or death which is an error screen. This stops the console and the user is requested to contact technical support. Another problem is that of the Xbox 360 freezing due to overheating. To solve this, users are requested to ensure proper airflow and a cooler environment. If the Xbox is moved from its vertical to its horizontal position while reading a disc, the movement causes the pickup assembly to brush against the disc resulting in radial scratches. Often the Xbox displays red lights instead of a green ring of light to indicate errors.
The X box360 transforms gaming experience into something futuristic and exciting.
CNC Machine Setup and Operation
CNC Machine Setup and Operation
Computer Numerical Control Machines are sophisticated instruments that only trained CNC operators should operate them. There are certain rules and guidelines to consider if you are planning to use a CNC machine by yourself.
CNC checklist before startup
Before starting up the Computer Numerical Control Machine, there are safety rules that must be considered first. First important aspect before starting up the CNC machine is to ensure your own safety, therefore wearing protective gear, such as eye glasses and short sleeved shirts is an important dress code during CNC operation. You should also be careful whenever you are handling tools and sharp edged work pieces to avoid any accidents. You must also ensure that the cutting tools are fastened in the machine spindle to avoid any movement during the cutting operation.
Actual Startup, Operation and Machine Setup of the CNC
The Computer Numerical Machine startup procedure varies depending with the type of machine being used but usually there is a main power switch or a circuit breaker to turn it on. Some machines also require hydraulics or air pressure before it starts up.
When the Computer Numerical Machine starts up, the machine usually starts at its Machine Home Position. The Machine Home Position allows the control and the machine to have a preset starting position for all its axes. After startup, the CNC machine must be sent to this position before the work begins. This position will later be changed to an appropriate location whenever you are machining a particular part of a product.
The Tool Length Offset Value or TLO is the distance from the tip of the tool from the spindle in the Home Position. The TLO must be set for each tool in the current job. The TLO can be set using a height gage, fixture location, as well as the reference tool. When these values are determined, they are stored in the Controller to be used during the program operation.
After setting the Tool Length Offset Value it is time to setup a part origin of a CNC machine. Setting up the part origin on a CNC machine is the same as setting up a conventional machine. It usually involves positioning the axes to a point where the plan designates as its origin. There are many ways to locate the position on the reference point, it is by using edge finders, wigglers or magnifying glasses.
After setting up the whole system for the Computer Numerical Control, it is time to Load the program to the machine. Program loading is different for each machine. Some machines have tape readers to input the program into the Computer Numerical Control Machine’s memory. Newer machines have internal or external floppy devices to input the program to the machine. After the program is loaded to the machine, the CNC machine is now ready to use.
There are certain instances when you have to change the tools in the Computer Numerical Control manually during machine operations. When a certain machining operation is complete, the program will move the aces to the tool change position and display the next tool needed. It is now the job of the Machine operator to remove and replace it with the next tool.
Extra Care must be taken whenever you are starting operations with the CNC machine, any mistake taken during the part of the operation may lead to serious injuries from the machine operator.
