The Different CNC Machines (part 2 of 2)

Electrical discharge machine

An electrical discharge machine (EDM) creates cavities in metals by emitting electric sparks. This process requires an electrode, coolant, a power source, and a tank. The cycle is accomplished by connecting the workpiece to one side of the power supply and then placing it in the tank. An electrode (made in the shape of the cavity required) is then connected to the other side of the power supply.

The tanks is then filled with coolant and the electrode is lowered until a spark jumps between the work and the electrode. As the coolant is a dielectric substance (resists electric currents), it requires a smaller difference in distance in order for a spark to jump through. This means that when the spark appears, the dielectric property has been overcome. The spark then dislodges material thereby creating a cavity in the shape of the electrode.

CNC systems

CNC systems are complex machines that transfer and store data regarding the operation mechanism of the machines. Motion programs include point to point control, straight cut control, and contouring control.

Point to point control means the control of the tools from one point to another in the coordinate plane. This method of control is commonly used in drilling and boring operations.

Straight cut control is the method by which a tool is moved in all axes of the machine. The tool also has the ability to move in a 45 degree angle.

Contouring control is the means to create a toolpath. It moves the tools by interpolating points or coordinates that make up the path for the tool to follow.

CNC has different applications depending on the machines that operate on it. So if you're a budding operator, you should know the most common machines that can operate on CNC.

Milling

Milling machines are common CNC machines. These devices are used in the shaping of metal and other solid materials. It is basically a rotating cutter and a table. Milling machines are capable of complex toolpaths as the cutter is not limited to a sideways movement but allows for an “in and out” motion. This movement is precisely controlled by moving the table and the cutter relative to each other. Cutting fluid is then pumped in to lubricate and cool the cut and to remove any swarth that is generated by the cut.

Lathes

Lathes are machines that perform different operations such as sanding, cutting, knurling, deformation, or even drilling. These machines work by spinning various solid objects and then using tools that are symmetric to the axis of rotation. A lathe machine has a single tool in which the workpiece is worked against the tool. The tool is then worked alongside or into the workpiece in order to generate the feed.

Lathes can be used for different operations.

Machining Centers

These are more complex CNC machines that combine milling and turning. As milling was described earlier, turning will be the focus of this section.

Turning is the process by which a central lathe is used in conjunction with the rotation of the material to be turned. The cutting tool is then moved along the two axes of motions to produce accurate dimensions.

Combining turning and milling can produce extremely precise components. And that is what these machines are used for. However, due to the complexity of these machines, operators have to be specialists in order to be able to operate with maximum efficiency.

2. Save with your consumption

Another way to do this is to make sure that you will be spending less for the household. You can do this by cutting expenses that are not necessary like in luxury items such as clothes, entertainment, trips. If you don't need it, don't buy it. Only purchase the items that you know you will be using.

You should also save with your consumption of electricity, gas and water as these are areas that you may not notice you are overbudgeting but usually you are. For instance, ironing clothes piece by piece and not by bulk consumes more electricity. The same goes with leaving the door open when the airconditioning unit is turned on. Always make sure that you turn off the TV after watching it or to be sure, purchase a unit that has a programmable on and off button that you can use. There are also airconditioning models and heaters that you can buy that have this feature.

3. Don’t panic

Economic recession as mentioned to you is a cycle and usually it will have an end. There is no need to feel panicky and feel that all hope is already lost. The more that you feel the panic, the more problems you will have because panic can make you do things without thinking about it or make you so nervous you will be mentally blocked out. So just ride the waves and go with the flow. You'll never even feel that it's there.

Economic recession may be a new term in your ears but in essence, it is actually a common economic term used to refer to the slowing down of economy. You see, a country's economy follows a natural cycle. Sometimes it's up and sometimes it's down. You just don't realize that it's happening because it has not gone this bad since the wall street crash decades before. Now, United States is feeling the heat once again with the rising costs of living and transportation as well as the crash of the real estate industry and just recently the crash of the top banks in the US.

During these times, all you can do is to hope and pray that you will still be able to keep your job and survive the recession until everything is ok again. To do this, you need to save up and make sure that you are ready for every eventuality. Here are some tips on how to deal with every American's concern right now.

1. Be prepared

What you know cannot kill you. There is nothing wrong and being prepared for potential problems. Even if right now, you don't have any problems financially, it pays to get ready for the coming challenges. You can do this by saving up some money and putting them in the bank. That way, you can use something for the rainy day.

Think of other ways that you can be prepared and plan around it. Look at your expenses every month and check where you can cut off the extras. With them side by side, you will know just where you are overbudgeting. This is also an excellent way to plan and save for future expenses like for instance, your children's tuition fees.

Straighten up and clean all rooms you have used in the entire duration of the vacation. You should consider that the homeowner would also come tired after the travel, so be considerate in maintaining the homeliness and coziness of the house. You should understand that a messy house would just add to the weariness and tiredness of the incoming exchange partner.
It is a good gesture if you buy and leave a gift for the homeowner.

If you run out of good gift ideas, try a coffee-table book, scented candles, a basket of fresh fruits, souvenir items, or wine. It would be sweet if you attach a small note to the gift. It would also be nice if you would send thank you notes to the exchange partner’s neighbors who have welcomed you cordially and warmly during your short stay.

Replenish the goods you have consumed from the fridge. It is a nice and standard practice to leave perishable products like bread, fruits, cheese, bottles of drinking water, soda cans, and probably wine. Do this as a sign of courtesy to the exchange partner and his family who would surely appreciate the gesture after they arrive from hours of travel.

If home exchange facilitated a pleasurable vacation experience, you may intend to keep on doing so in the future. It is important that you kept your record clean and untarnished so that your exchange partner would be able to share it to his friends and acquaintances how good and responsible you are as home exchange guests.

As a decent and responsible homeowner, you should treat other homes as your own.

As you have prepared your home for the exchange arrangement, you should also prepare the home of your exchange partner before turning it back. Of course, you are also expecting to go back to a home in clean and good condition. How do you prepare to leave the exchange partner’s home? Here are some tips.

First, wash the linen and sheets you have used and fold them before putting on top of the bed after drying. Likewise, clean kitchen and bathroom towels. You may leave a short note informing the exchange partner that you have done so. Intend to leave the home exactly the way it is when you came over.

Do not forget to sweep the floor before going. It is a good deed that you mop, vacuum carpets, and put dishes (clean) back where they rightfully belong. If you have broken any plate, buy a replacement but make sure the item is exactly the same. Leave a note to inform the homeowner you did some replacement of ruined items.

If you have to build fire, be sure to establish a fire ring, fire pan or mound fire. Since you also need wood, be sure to only use sticks that can be broken by hand. The following morning, make sure all the wood has been burned to ashes and then scatter it around.

When you go camping in the forest, you are entering a domain where wild animal roam. If you seem them from a distance, don’t make any attempt to follow or approach them. Since some camps in France allow you to bring your dog along, make sure it is leashes and their waste disposed of properly.

Chances are you not the only one going camping so if you see other people, be considerate and courteous. This means resting and making camp away from other groups, stepping to the downhill side of a trail when encountering pack stock and avoiding making loud noises.

When you go camping, you can’t help but produce some waste. Before you leave, don’t just leave it there but pack everything up and dispose of this properly. For human waste, dig a hole at least 6 to 8 inches deep and cover it up when finished.

For those that will be washing dishes, carry water 200 feet away from any lakes or streams. Use biodegradable soap and then scatter the strained dishwater.

Now that you know the ethics of camping, practice it. This will make the camping trip in France a memorable for you and your family as well as to whoever goes there in the future.

Camping is a great recreational activity and each experience is always different from the last. In order to preserve the beauty of the place, there are some ethics you have to practice even while camping in France.

When you camping similar to staying in a hotel, remember that you are a guest. So before you get there, plan ahead and prepare everything that you need. You should also abide by the rules and regulations set at the campgrounds as this is for the safety of everyone there.

You can’t help but sometimes get lost when you go camping. Instead of marking where you made a turn by using paint or flagging, bring a compass instead or bring along a device that is more high tech like GPS.

Setting up camp should always be done on durable surfaces specifically dry grass, gravel, rock or snow. If the area has been designated as a campsite, leave it just the way it is since alternation is not necessary. You can do your share of protecting riparian areas by camping at least 200 feet from lakes and streams.

If your group is walking or going on a hike, walk single file when the soil you are stepping on is muddy or wet. If you some interesting things like historic artifacts or historic structure, look but don’t touch. Never bring home or introduce anything new in the area.

Teach Composting to Kids (part 2 of 2)

Track for feedback

Kids can get opinionated about things that they like. Strike their fancy even further by getting feedbacks from them from time to time. Also, ask them and encourage them to ask their questions to you. Removing their inhibitions will help you teach them more concepts than when you are dealing with an uptight bunch,

Entertain all questions and give ample time to answering each question.

Kids can get easily discouraged. So make sure that you are able to reserve judgment and entertain questions, no matter how “stupid” or minor they may seem to you. Remember, you are dealing with children here. If at all possible, have an assistant teacher who is also a kid to help you gain a better perspective of teaching composting to children.

Discuss benefits at the outset so they will know what composting is really for.
If the children are oriented from the outset that what they are doing has great significance, they are more likely to cooperate and do the tasks cheerfully. Ensure that you are fully able to help them understand how composting helps the environment and how it will make a positive difference to a majority of people.

Let them do it, and refuse to interfere if possible.

The main purpose for educating them on composting is to have them equipped with  the skills they need to be able to do composting themselves. So, seeing them do the composting, even on a small pit for beginners, may help you see where potential problems may lie. You can also easily praise them and correct them as necessary.

In any case, encourage them for every form of progress made, no matter how small it is, so as to help build their confidence.

Teach Composting to Kids (part 1 of 2)

Composting education drive is another way to ensure that you are able to pass on the legacy to younger generations. But packaging the teaching method is another aspect that the composting enthusiast must not overlook. There are various ways of teaching composting to adults, but children have different needs and may require more than the expertise of monitoring your heap's temperature.

Here are different techniques for teaching composting methods to children. It can really be fun and rewarding to pass on the baton to younger kids once you have gotten the hang of composting, and it will really help bring about awareness to their parents and other members of the community.

Use Visuals

Nothing beats the boring feeling a kid gets from pure text. Unless the kid is inclined to enjoy pure words, visuals are your best bet into inculcating a love for composting. Make use of pictures, Powerpoint presentations and other technological devices you can use. If you are on an impromptu teaching class, use your words to help the kids visualize the scenario of composting. In any case, encourage the children to imagine the entire process.

Do a complete demo

The demonstration will be able to teach volumes to the children, way more than any discussion can. With a demonstration, you not only show them how it's done, you also show them that you are well capable of doing what you are teaching them. Seeing the actions in real time will also eliminate the need for them to ask questions should their turn for trying it comes since they will be able to present their questions as you do your demo.
