3 Basic Motion Types in a CNC Machine (part 2 of 2)

2.)Straight Line Motion

This type of motion would allow the programmer of the machine to command perfectly straight line movements within the machine. Unlike the rapid motion type, the straight line motion would allow the programmer to vary the rate of the motion or feed rate to be used during the movement. Examples of using straight line motion would be turning a straight diameter, taper, when milling straight surfaces, and when drilling for this is because these examples require straight cutting movement.

The common word to specify a straight line motion into a machine would be G01, for within this command the programmer will include the preferred end point within each of the axes.

3.)Circular Motion

This motion type would cause the machine to move in the direction of a circular path and is used to generate the radii in machining. When talking about points on circular motion feed rate, it is equal to that of straight line motion.

Other than that of straight line motion and rapid motion, there are two G codes that are commonly used when programming a circular motion into a machine. These are G02 and G03. G02 is used when the programmer desires a clockwise motion into the machine while G03 is used to make an anti-clockwise motion. To know which of the commands to use, the programmer must view the movement with the same perspective as to what the motion of the machine will be, may it be clockwise or anti-clockwise.

Another requirement that would be programmed into a machine that would be using circular motion is that the programmer must specify the radius of the arc that is to be generated. With brand new technological advances in CNC, an “R” word is now used to specify the radius.

For older controls in CNC machinery, an “I”, “J”, and “K” are used to specify location of the center point of the arc.

A Computer Numerical Controlled (CNC) machine may have more than one motion type that it uses, but there are three most common motion types that are easy to remember. These are the Rapid Motion, the Straight Line Motion, and the Circular Motion.

All of these motion types may seem different but they share two things in common, which would be that they are all modal and the endpoint of each motion is specified in motion command. By being modal it means that the motion type would be in effect until changed otherwise.

3 common motion types:

1.)Rapid Motion Type

Rapid motion type is also called Positioning. The way this motion type is used is through utilizing the fastest rate possible of the command motion of the machine. Example uses of rapid motion are moving to clear obstructions, placing cutting tools to and from the desired position, and any program that provides non-cutting in their schemes.

The command that is usually programmed to a CNC machine is G00 because in this command, the end point for the rapid motion would be specified.

The CNC machine, with most controls given, will be able to move as fast as possible in all commanded axes. In the case of rapid motion, one axis may be able to reach its end point before other axes. Straight line movement will not occur with type of rapid command function and the programmer of the machine must take into account that there are no obstructions to avoid. Straight line motion will happen even during rapid motion commands when done with other controls.

What is an Economic Recession (part 2 of 2)

http://www.bromotravelindo.com

Despite the fact that the country has endured this time and again for over 50 years, there is still no way to predict when it will happen.

Some use the stock market as an indicator. Others use the inverted yield curve which uses yields on a 10 year and three month Treasury securities and the Fed’s overnight fund’s rate. The unemployment rate is also another which happens to be one of the things that make up the index of leading indicators.

There are people in the Bush administration who do want to call it an economic recession because this will make people panic but there are others who are brave enough to admit that it is here. Since it is going to be some time before the economy recovers again, everyone is advised to stay calm, save up and look for long term investments worth going into.

Apart from the war in Iraq, the economy is going to be one of the critical issues that both candidates have to address as they are campaigning for the highest post in the land. Whoever wins, they have to find a way to reduce the unemployment rate, help people save their homes and a lot of other things that affect the average American household.

An economic recession lasts months at a time. If it should continue for a much longer period, then this is called a depression which is something that the world and not only the US experienced at the end of the First World War. This lasted for up to 4 years that many hope will never happen again.

What is an Economic Recession (part 1 of 2)

http://www.bromotravelindo.com

What is an economic recession? This occurs when there is a significant decline in the economy which usually lasts for months. This is visible in terms of consumer spending, employment, industrial production, real income and wholesale trade. A technical indicator of this is 2 consecutive quarters of negative growth which is measured by the country’s GDP or gross domestic product.

Experts say that an economic recession is normal because it is part of the business cycle and things usually improve within 16 to 18 months.

During the business cycle, there is a period of recovery, expansion, slowdown and then recession. During recovery, the GDP of a country starts to move up. When the GDP grows robustly, this is the time that it expands. When consumers are not buying that much, this is when you have a slowdown. Because there is weaker demand, you have a recession.

The last economic recession occurred in 2000 and 2001 which featured three quarters of negative growth followed by three positive quarters then five more quarters of sub par growth. Experts say that the same trend will happen right now.

One solution that the government usually does is lower interest rates to help stimulate the economy. Just last year, the Federal government slashed interest rates three times towards the end of the third and fourth quarter year so that overnight loans between banks could be borrowed at 4.25% which happens to be its lowest in the past 2 years.

What makes the economic recession different from what occurred after the Second World War is that this one is caused by falling home values and a crisis of confidence among fixed income investors.

The Relationship Between Human Population And Deforestation (part 2 of 2)

The Historical Trends

Presently, deforestation research and studies show a few conclusions that can be made. At minimal population mass, it is achievable to preserve intact forests with vast land areas. Instead of the population being sustained primarily through agricultural land transformations, they can easily be fed with only small harvests with no particular need for land cultivation.

However, even in lightly inhabited locations, outside forces such as stipulation for cattle and lumber in other parts of the world can result to deforestation that is not directly associated to the confined population. This has proven to be one of the leads to deforestation in huge forests such that of the Amazon. They produce not for their own sustenance, but for the neighboring needs of other growing countries.

As the population increases, the demand to clear more forests also increase; likewise, the need for indispensable consumption drives people towards nature since there are no other viable forms of human survival. It is only a basic instinct to man that he feeds himself for the issue of continued existence. However, there can be methods to preserve the forest and yet still benefit from it. Usually, greed and power result to the damaging effects of deforestation. If it is controlled in rate, then the possibility of not harming the nature is a likely thing to happen.

What Man Can Do

Clearly, human population and deforestation are inseparable terms. Where there is a call for food, the need for land also arises; and the demand of logging and agricultural cultivation happens widely all over the planet. The means of not harming the earth while still surviving is very attainable. In bringing this to reality, we need men who are honored and dignified enough to protect the earth and its resources. The humans need to safeguard their treasures which they can benefit from all the time.

Nature finds its way back at us when we know how to nurture and nourish it. What man can do is simply about what man is willing to do.

The Relationship Between Human Population And Deforestation (part 1 of 2)

The term human population and deforestation have been used interchangeably through the thickness of time. Could this mean that the growing crowd of humans be the leading cause of our forest depletion today? Well, possibly that could really be the case.

After all, humans are responsible for everything that's happening in the planet, from the cutting of trees to the widening of roads and to the construction of infrastructures. They say that humans build for a better world, but is that really their purpose? Are humans actually building for the world or are they fostering for themselves?

It is unrealistic to emphasize the magnitude of destruction of humankind's wiping out of the forests. The conversion of forested lands by human deeds denotes one of the greatest threats in global environmental variation and one of the eminent drivers to biodiversity death. The influence and bearing of the people has been and carries on to be extremely overpowering.

Our vast resources are cleared, corrupted and disintegrated by lumber garner, transformation to crop growing, road construction, man made fires, and in countless further ways. The attempt to utilize and mollify the forest has been an invariable premise in the revolution of the earth, in various communities, and in many countries.  Deforestation and human growth has indeed brought a heap of implications in our planet.

The Healing Benefits of Fish oil (part 2 of 2)

http://www.bromotravelindo.com

Fish oil has been adopted as a good treatment for internal diseases for over a thousand years now and traces its roots back to ancient Japanese and Chinese natural healing methods.

Currently, thousands of cardio vascular sufferers have benefited from the healing powers of fish oil, and many of these consistent testimonials are that it significantly relieves stress and anxiety, strengthens the body's natural self-healing ability, balances the functions of the human organs and glandular systems, promotes a positive spiritual and emotional well-being, enhances relaxation including sleep, relieves pain, removes toxins from the body and strengthens the body's immune system.

Today, cardio vascular diseases and fish oil are mutually associated with each other, since a growing number of cardio vascular patients have found fish oil to be a healthy alternative to the treatment of the disease, although it is pointed out that it is not a direct healing medication that will actually 'cure' the disorder, its supplemental properties- when administered accordingly with conventional treatment- hastens the healing process.

The healing benefits of fish oil – especially for those suffering from cardio  vascular  diseases - are not just made popular by lip service or media hype, but more from the results of a healing experience that have eased the suffering and pain of thousands of those with cardio vascular diseases.  

Science and technology has indeed found a way to harness this wealth of the deep for the benefit of mankind and now that we have it at the palm of our hands and what better way to make the most of it is to embrace the healing benefits of fish oil to our day to day living, be it for treatment or even just as a health supplement.

The Healing Benefits of Fish oil (part 1 of 2)

"What are the healing benefits of Fish oil and how can it help someone with cardio  vascular diseases?"

This is one of today's biggest question on one of this century's enigmatic disease called cardio vascular  diseases, which is often associated with one’s lifestyle, diet and even stress and depression.

The primary cause of cardio vascular  diseases is still not known, however, experts agree that emotional or physical trauma are among the factors that develop the disease. Some experts also believe that cardio vascular patients have constant abnormal transmission responses to pain.

Insomnia and other sleep disorders are also common in cardio vascular patients, leading to increased stress levels on the patient and could rapidly spread the disease throughout the human body, while another theory supposes that cardio vascular  diseases is also linked to the metabolical changes in a person's blood flow, leading to symptoms of weakness and chronic fatigue.

A much more simpler theory suggests that cardio  vascular  diseases may be inherited and flows along family lines, still there is also no proof to attest to that claim.

Although there is no established prevention for cardio  vascular  diseases to occur in a person, the management and treatment of the disease has significantly improved and advanced over the years.

Despite the somewhat enigmatic cause of this disease, one treatment method that is popularly adopted by cardio vascular patients is an Asian therapeutic treatment approach is fish oil supplements, since it is a very good source of Omega 3 acids which significantly help in ensuring good oxidation in the body and helps improve blood circulation and muscle strengthening, among them the human heart.

Body Language At Work ( part 1 of 2)

Art of Animation

Make use of your hands to punctuate or emphasize what you are saying. You will appear stiff if your hands will stay on your lap during the entire period of the interview. Hand gestures also signifies that you are honest and indeed knowledgeable of what you are talking about. You can do this while sitting or standing. During a presentation, move around, but walk slowly. The greatest presenters are those who can speak confidently with the right timing of body movements and gestures.

Gestures And Movements To Avoid

The wrong gestures, done consciously or unconsciously, could give the wrong impression to your boss, co-workers, and clients. These may be the reason of you getting fired. Therefore, you must avoid the following acts of body language.

Avoid pointing a finger at somebody, especially your boss. Even when you are angry or trying to emphasize a detail, it is regarded as a rude gesture. In meetings, refrain from showing signs of boredom and lack of interest. These signs include arms crossed over the chest, eyes on objects other than the person talking or the presentation itself, yawning, signing, drumming the fingers on the table, or tapping your foot.

Signs That You Are Not Doing A Good Job

If you are the presenter in a meeting or an applicant in a job interview, you must observe the body language of your audience as well. Reading their actions and movements could aid you to be aware of their reactions and if you are doing well.

You would detect if the other party is getting bored if their focus of attention is not on you. This is evident by the absence of eye contact. Observe their hands as well. Even if their eyes are on you, but if their hand are busy, it may mean they are thinking of something else. See if their fingers are playing with their pen or drumming on the surface of the table. Boredom is also indicated when the person in front of you begin to slouch back into their chair.

Signs of opposition to your ideas and opinions are also determined when the other party crosses their arms, wrinkle their forehead, and tilt their head.

However, the signs above sometimes do not reflect how someone really feels. What is important is that you know how to prepare yourself in critical times at the workplace.

Body Language At Work (part 1 of 2)

You can always use body language as a key to success in your work. You could give a good impression, convince clients, and please your boss. In communication, only 7% are the words and rest of the 93% is accounted for the nonverbal cues, which includes the aspects of speech and body language.

Appropriate Body Language During An Interview, Meeting Or Presentation

A job interview is usually nerve-wracking. But in order not to be included in the list of rejected applicants, you have to impress your interviewer by being confident. Here are the gestures and body movements you must observe during a job interview.

A firm handshake indicates confidence. Relax on the chair provided for you, but do not slouch. Slouching reflects laziness. Keep your heap up, and lean slightly forward. Place your hands on your lap, and never in your pocket. The hands-in-pocket gesture signifies nervousness, boredom, and dishonesty. As much as possible, do not cross your legs. But if crossing your legs would help calm your nerves, you may do so but point your body towards the direction of the interviewer. During the conversation, make sure you maintain eye contact to show your interest and eagerness to listen.

A Look Back at how Vanessa Hudgens Started in her Acting Career (part 2 of 2)

For the two equally successful “High School Musical” TV movie, Hudgens played the role of Gabriella Montez. She played the love interest of real-life boyfriend, Zac Efron. Their roles had given them the “Best Chemistry” award given by Teen Choice Awards. The first movie also had a hit soundtrack and it brought the group on a concert tour worldwide. A book series was also made out of it.

With all the success she has garnered, Hudgens became the number seven on Forbes magazine’s top earning list of stars who are under 21. She was 18 years old at the time. She has an estimated $2 million of earnings. “High School Musical 3: Senior Year” is set to be released on October 24, 2008.

This talented gal was ranked 62nd of the Most Sexiest Woman on FHM just this year. She was also at number 12 at Maxim’s 100 Hot List. And she was also part of People magazine’s 100 Most Beautiful People.

Life on the Spotlight He career was marked with controversy when provocative pictures of Hudgens proliferated the Internet on September 6, 2007. The photos were passed on through emails, mobile phones and other devices. There were rumors then that she would be pulled out from the High School Musical franchise because she was no longer fit to be called a model for the youth.

But everything was settled. And Hudgens apologized to the fans and her family. After that, all is well again for this young superstar. Just looking back on how did Vanessa Hudgens get started in her acting career will inspire young minds about this craft if they are planning on joining the bandwagon.

A Look Back at how Vanessa Hudgens Started in her Acting Career (part 1 of 2)

How did Vanessa Hudgens get started in her acting career? This girl was born Vanessa Anne Hudgens on December 14, 1988 in Salinas, California. Her looks can be attributed to her parents’ descents. Her dad, Greg Hudgens is an American with the Native American and Irish background. Her mother, Gina, is a Filipino who grew up in Manila with traces of Filipino, Chinese and Spanish blood.

 Career Path Vanessa was inclined on the performing arts since she was a child. After she finished seventh-grade at the Orange County High School of the Arts, Vanessa opted for a home school setup.

When she was eight years old, she began joining musical plays. She was included on the main and supporting casts of plays such as "The Wizard of Oz," "The Music Man," "Damn Yankees," "Evita," "Carousel," The King and I," and "The Music Man.” Everything happened by chance for little Vanessa. Her first gig was a commercial. But it was purely accidental why she landed the part. She went on the audition just because her friend, who was supposed to go there, got sick and asked her to come instead.

In 2003, she debuted in the feature film "Thirteen." This stars Evan Rachel Wood and Holly Hunter. Vanessa also starred in "Thunderbirds," an action-adventure film. But Hudgens hit it big after playing the part of Gabriella in High School Musical, a TV movie made by the Disney Channel that was first released in 2006. That same year, she was able to release her debut album entitled “V.” In July of 2008, her second album entitled “Identified” was released.

After she started on movies, she also played bit roles for television. She guest starred for TV shows such as “The Bothers Garcia,” “Still Standing,” “Quintuplets,” “Drake and Josh” and “The Suite Life of Zack and Cody.
