Home Theater Setup Basics
Time to turn an area of your home into an entertainment area? Tune up your house with a home theater by following these basic steps.
1. Determine where you would like your system set up: in a family room, an entire basement level or only one section, etc. Grab a pencil and some graph (or other) paper and get to work with a blueprint. Don’t leave this to “notions” or things get messed up – and quickly. Pencil in (a) your focal point – usually a television or other huge screen or home theater personal computer (HTPC) (b) seating (c) other main screens – projector and table / speakers and amps / computer / gaming consoles / DVD player, cable box and VCR (d) storage – shelves / remote and guide organizer (e) misc. – do leave some empty space. Cramped quarters are no fun!
2. Next, research your family needs. A home theater can incorporate: video game playing with any of the popular console systems like from Xbox, Nintendo or Playstation; it can feature a computer, DVD player and other recording and playing devices. Plus it can feature fancy audio equipment with multiple speakers. Add seating, lighting and screens into the mix. And plan ahead, too, looking to the future a little to prepare for the unexpected and for growth. For example, add extra outlets (for phone hook ups / computers / power supplies / cell phone, battery and other chargers, etc and leave extra space for the unexpected – extra shelves, equipment add-ons, storage for DVDs, CDs and remotes, etc. Grab your blueprint from above and pencil in your ideas.
3. Then comes set up time! Begin with your focal point and consider that your projector can reach to adjust distance from the screen for maximum effect. Test equipment at this stage before adding everything else into the area to make sure you get the results you like. After visuals, add audio into the mix. Set up your surround sound amp with plenty of video and audio inputs for all your fun systems. Then add the speakers and test again.
4. Then arrange other items (if you have a media center computer, many of these may already be part of the system): VCR, DVD player, gaming console and other equipment. Then round out everything with seating, lighting, shelves, storage organizers, etc.
Party time! Invite your family, friends and neighbors over to enjoy and celebration. Have fun!
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.
