ISE 370 MANUFACTURING Introduction Numerical Control (NC) is the basis for many manufacturing processes in today’s industry. NC is the operation of machine tools and other processing machines by a series of coded instructions. CNC or computer numerical control systems include a built-in computer to support the machine and process. The main objective of this project was to simulate how a CNC machine is used in industry to facilitate a process and fabricate a designed part. In this course the importance, uses, and limitations of CNC machines when applied to the industrial world have all been learned. This assignment offered the opportunity to experience and evaluate the effects of a CNC machine on a process and vice versa. This is most important in the fast paced, changing world of industry we now live in. The goals of this project were to design a part, write a code for the Fadal CNC machine, learn how to enter the code and operate the machine, and effectively fabricate the object from a block of wax. A University of Georgia â€Å"G† was to be the designed (Figure 1). The most difficult aspect of this project was determining how to make the CNC draw an ellipse. Because of this problem, the team wasn’t sure if they would be able to draw the appropriate design. There was discussion of making changes, in order to simplify the program. The adversity was met head on, however, and the original design was ultimately kept. Experiment/Method The first step after determining what was to be cut by the CNC was to design the part using a CAD program. Due to the familiarity of the team with AutoCAD, this was the program of choice to draw the â€Å"G†. It became immediately apparent upon drawing the object, that this could be a very challenging design due to the inclusion of ellipses. The CNC codes supplied as reference material included how to draw arcs, but there was no information on drawing an ellipse. The team attempted to use I and J coordinates to create an ellipse. This proved to be an incorrect approach. When the program was entered into the machine the picture drawn on the machine did not at all resemble a â€Å"G†. The team went back to the drawing board with another idea at hand. It is also possible to draw arcs using RF coordinates, which required finding radii.

Marquette University Essay

Marquette is ranked No. 63 by high school and private independent school guidance counselors in 2012. It’s located in Milwaukee, Wisconsin. Marquette is known for its outstanding academics, and varying majors. Additionally, Marquette is a Catholic Jesuit college, which means there are a lot of spiritual bases in finding God in everything that is done. This means in education we can find some inspiration to do better and be better, no matter what is one’s faith or traditions; the common ground for almost everything is education and its importance. With a degree from Marquette comes a lot of bragging rights, and is highly looked upon. When applying for a job Marquette stands out on a resume over most universities and colleges. Marquette is one the best universities offered in Wisconsin besides UW Madison. I believe I would like to further my first class education with Marquette because of great programs offered and the greater spiritual background received with a degree. Marquette is a top notch school and attracts a lot of perspective students, but turns them away with $40,000+ tuition a year, including room and board. To help with tuition Marquette offer a lot of scholarships to the most deserving students, and also have a great program for work grant for working for paying for college as in the cafeteria. The Free Application for Federal Student Aid (known as the FAFSA) is a form that can be prepared annually by current and prospective college students (undergraduate and graduate) in the United States to determine their eligibility for student financial aid (including the Pell Grant, Federal student loans and Federal Work-Study). Also, student loans are very reasonable and sometimes money is taken off by volunteering and community participation. Marquette and Madison are two of the best universities Wisconsin has to offer. While this is very high, this should not turn away perspective students away because they are so many scholarships that can be claimed. The ball is in the court of the student, and how proactive they are towards having reduced tuition. There is always a way around high costing tuition as in grants, scholarships, and work study/grant. Also, with the admissions into Marquette the range for ACT score is from 24-29, class rank top %33 – %8, and %25 high or lower also are admitted. Marquette offers over 115 different majors and minors in which each student has the opportunity to hone their skills. The most popular majors at Marquette University include: Business, Management, Marketing, and Related Support Services; Communication, Journalism, and Related Programs; Engineering; Health Professions and Related Programs; and Social Sciences. Within these programs we find almost all states and 70 countries represented in student population, and the average classroom size is 31 students. There is a program offered called the FFP short for Freshman Frontier Program. The Freshman Frontier Program is designed to expose freshman to college academics in a gradual way that is meaningful to you. The program begins in the summer before a freshman first term at Marquette with a five-week session on campus when freshman take credit and non-credit courses. Marquette offers a very spiritual background in the art of reflection, which is heavily influenced by its Catholic Jesuit ancestry. Faith and spirituality are an important part of life at Marquette. As a Catholic, Jesuit institution, Marquette provides an environment that foster spiritual growth in people of all faiths through religious services, community service, and personal and group retreats. Students, faculty and staff find opportunities to develop spiritually through conversations about things that matter, faith, God, social justice, a search for truth, the desire for peace. â€Å"Faith and spirituality affect the way teaching, learning, research and living take place on campus†. A strong spiritual base is needed in the young women and men of the future, either Catholic, Christian, or others there is always a spiritual connection to something, and with this the Jesuits ties it in with education and everyday life. To sum it up, Marquette continually stays on the top ranked universities in the nation, and will continue to do so if they keep up their great programs and spiritual background. The high tuition can always be subsidized by grants, scholarships, and work grant. FAFSA is a great a way for students to be prepared for the year ahead and to earn some money off of the entire tuition. This should not turn away perspective students, but should attract them for the thrill of working hard for things that are wanted. But with this, a life lesson is learned, nothing in life is free, people must work for what they want and need. That’s why I believe Marquette is a great college for me to continue my spiritual and first class education. Work Cited â€Å"WE ARE A CATHOLIC AND JESUIT UNIVERSITY. † Catholic and Jesuit.

The History of Buenos Aires, Argentina

One of the most important cities in South America, Buenos Aires has a long and interesting history. It has lived under the shadow of the secret police on more than one occasion, has been attacked by foreign powers and has the unfortunate distinction of being one of the only cities in history to be bombed by its own navy. It has been home to ruthless dictators, bright-eyed idealists and some of the most important writers and artists in the history of Latin America. The city has seen economic booms that brought in stunning wealth as well as economic meltdowns that have driven the population into poverty. Foundation of Buenos Aires Buenos Aires was founded twice. A settlement at the present-day site was established briefly in 1536 by conquistador Pedro de Mendoza, but attacks by local indigenous tribes forced the settlers to move to Asuncià ³n, Paraguay in 1539. By 1541 the site had been burned and abandoned. The harrowing story of the attacks and the overland journey to Asuncià ³n was written down by one of the survivors, German mercenary Ulrico Schmidl after he returned to his native land around 1554. In 1580, another settlement was established, and this one lasted. Growth The city was well-located to control all trade in the region containing present-day Argentina, Paraguay, Uruguay and parts of Bolivia, and it thrived. In 1617 the province of Buenos Aires was removed from control by Asuncià ³n, and the city welcomed its first bishop in 1620. As the city grew, it became too powerful for the local indigenous tribes to attack, but became the target of European pirates and privateers. At first, much of the growth of Buenos Aires was in illicit trade, as all official trade with Spain had to go through Lima. Boom Buenos Aires was established on the banks of the Rà ­o de la Plata (Platte River), which translates to River of Silver. It was given this optimistic name by early explorers and settlers, who had gotten some silver trinkets from local Indians. The river didnt produce much in the way of silver, and settlers didnt find the true value of the river until much later. In the eighteenth century, cattle ranching in the vast grasslands around Buenos Aires became very lucrative, and millions of treated leather hides were sent to Europe, where they became leather armor, shoes, clothing and a variety of other products. This economic boom led to the establishment in 1776 of the Viceroyalty of the River Platte, based in Buenos Aires. The British Invasions Using the alliance between Spain and Napoleonic France as an excuse, Britain attacked Buenos Aires twice in 1806 to 1807, attempting to further weaken Spain while at the same time gaining valuable New World colonies to replace the ones it had so recently lost in the American Revolution. The first attack, led by Colonel William Carr Beresford, succeeded in capturing Buenos Aires, although Spanish forces out of Montevideo were able to re-take it about two months later. A second British force arrived in 1807 under the command of Lieutenant-General John Whitelocke. The British took Montevideo but were unable to capture Buenos Aires, which was ably defended by urban guerilla militants. The British were forced to retreat. Independence The British invasions had a secondary effect on the city. During the invasions, Spain had essentially left the city to its fate, and it had been the citizens of Buenos Aires who had taken up arms and defended their city. When Spain was invaded by Napoleon Bonaparte in 1808, the people of Buenos Aires decided they had seen enough of Spanish rule, and in 1810 they established an independent government, although formal Independence would not come until 1816. The fight for Argentine Independence, led by Josà © de San Martà ­n, was largely fought elsewhere and Buenos Aires did not suffer terribly during the conflict. Unitarians and Federalists When the charismatic San Martà ­n went into self-imposed exile in Europe, there was a power vacuum in the new nation of Argentina. Before long, a bloody conflict hit the streets of Buenos Aires. The country was divided between Unitarians, who favored a strong central government in Buenos Aires, and Federalists, who preferred near-autonomy for the provinces. Predictably, the Unitarians were mostly from Buenos Aires, and the Federalists were from the provinces. In 1829, Federalist strongman Juan Manuel de Rosas seized power, and those Unitarians who did not flee were persecuted by Latin Americas first secret police, the Mazorca. Rosas was removed from power in 1852, and Argentinas first constitution was ratified in 1853. The 19th Century The newly independent country was forced to continue to fight for its existence. England and France both tried to take Buenos Aires in the mid-1800s  but failed. Buenos Aires continued to thrive as a trade port, and the sale of leather continued to boom, especially after railroads were built connecting the port to the interior of the country where the cattle ranches were. Towards the turn of the century, the young city developed a taste for European high culture, and in 1908 the Colà ³n Theater opened its doors. Immigration in the Early 20th Century As the city industrialized in the early 20th century, it opened its doors to immigrants, mostly from Europe. Large numbers of Spanish and Italians came, and their influence is still strong in the city. There were also Welsh, British, Germans, and Jews, many of whom passed through Buenos Aires on their way to establish settlements in the interior. Many more Spanish arrived during and shortly after the  Spanish Civil War  (1936 to 1939). The Perà ³n regime (1946 to 1955) allowed  Nazi war criminals  to migrate to Argentina, including the infamous Dr. Mengele, although they did not come in large enough numbers to significantly change the nations demographics. Recently, Argentina has seen migration from Korea, China, Eastern Europe and other parts of Latin America. Argentina has celebrated Immigrants Day on September 4 since 1949. The Perà ³n Years Juan Perà ³n  and his famous wife  Evita  came to power in the early 1940s, and he reached the presidency in 1946. Perà ³n was a very strong leader, blurring the lines between elected president and dictator. Unlike many strongmen, however, Perà ³n was a liberal who strengthened unions (but kept them under control) and improved education. The working class adored him and Evita, who opened schools and clinics and gave state money away to the poor. Even after he was deposed in 1955 and forced into exile, he remained a powerful force in Argentine politics. He even triumphantly returned to stand for the 1973 elections, which he won, although he died of a heart attack after about a year in power. The Bombing of the Plaza de Mayo On June 16, 1955, Buenos Aires saw one of its darkest days. Anti-Perà ³n forces in the military, seeking to dislodge him from power, ordered the Argentine Navy to bombard the Plaza de Mayo, the citys central square. It was believed that this act would precede a general coup dà ©tat. Navy aircraft bombed and strafed the square for hours, killing 364 people and injuring hundreds more. The Plaza had been targeted because it was a gathering place for pro-Perà ³n citizens. The army and air force did not join in the attack, and the coup attempt failed. Perà ³n was removed from power about three months later by another revolt which included all of the armed forces. Ideological conflict in the 1970s During the early 1970s, communist rebels taking their cue from  Fidel Castros  takeover of Cuba attempted to stir up revolts in several Latin American nations, including Argentina. They were countered by right-wing groups who were just as destructive. They were responsible for several incidents in Buenos Aires, including  the Ezeiza massacre, when 13 people were killed during a pro-Perà ³n rally. In 1976, a military junta overthrew Isabel Perà ³n, Juans wife, who had been vice president when he died in1974. The military soon began a crackdown on dissidents, beginning the period known as La Guerra Sucia (The Dirty War). The Dirty War and Operation Condor The Dirty War is one of the most tragic episodes in all of the History of Latin America. The military government, in power from 1976 to 1983, initiated a ruthless crackdown on suspected dissidents. Thousands of citizens, primarily in Buenos Aires, were brought in for questioning, and many of them disappeared, never to be heard from again. Their basic rights were denied to them, and many families still do not know what happened to their loved ones. Many estimates place the number of executed citizens around 30,000. It was a time of terror  when citizens feared their government more than anything else. The Argentine Dirty War was part of the larger Operation Condor, which was an alliance of the right-wing governments of Argentina, Chile, Bolivia, Uruguay, Paraguay, and Brazil to share information and aid one anothers secret police. The Mothers of the Plaza de Mayo is an organization of mothers and relatives of those who disappeared during this time: their aim is to get answers, locate their loved ones or their remains, and hold accountable the architects of the  Dirty War. Accountability The military dictatorship ended in 1983, and Raà ºl Alfonsà ­n, a lawyer, and publisher, was elected president. Alfonsà ­n surprised the world by quickly turning on the military leaders who had been in power for the past seven years, ordering trials and a fact-finding commission. Investigators soon turned up 9,000 well-documented cases of disappearances and the trials began in 1985. All of the top generals and architects of the dirty war, including a former president, General Jorge Videla, were convicted and sentenced to life imprisonment. They were pardoned by President Carlos Menem in 1990, but the cases are not settled, and the possibility remains that some may return to prison. Recent Years Buenos Aires was given autonomy to elect their own mayor in 1993. Previously, the mayor was appointed by the president. Just as the people of Buenos Aires were putting the horrors of the Dirty War behind them, they fell victim to an economic catastrophe. In 1999, a combination of factors including a falsely inflated exchange rate between the Argentine peso and the US dollar led to a serious recession and people began losing faith in the peso and in Argentine banks. In late 2001 there was a run on the banks and in December 2001 the economy collapsed. Angry protestors in the streets of Buenos Aires forced President Fernando de la Rà ºa to flee the presidential palace in a helicopter. For a while, unemployment reached as high as 25 percent. The economy eventually stabilized, but not before many businesses and citizens went bankrupt. Buenos Aires Today Today, Buenos Aires is once again calm and sophisticated, its political and economic crises hopefully a thing of the past. It is considered very safe  and is once more a center for literature, film, and education. No history of the city would be complete without a mention of its role in the arts: Literature in Buenos Aires Buenos Aires has always been a very important city for literature. Porteà ±os (as the citizens of the city are called) are literate and place great value on books. Many of Latin America’s greatest writers call or called Buenos Aires home, including Josà © Hernà ¡ndez (author of the Martà ­n Fierro epic poem),  Jorge Luà ­s Borges  and Julio Cortà ¡zar (both known for outstanding short stories). Today, the writing and publishing industry in Buenos Aires is alive and thriving. Film in Buenos Aires Buenos Aires has had a film industry since the beginning. There were early pioneers of the medium  making films  as early as 1898, and the world’s first feature-length animated film, El Apà ³stol, was created in1917. Unfortunately, no copies of it exist. By the 1930s, the Argentine film industry was producing approximately 30 films per year, which were exported to all of Latin America. In the early 1930s, tango singer  Carlos Gardel  made several films which helped catapult him to international stardom and made a cult figure of him in Argentina, although his career was cut short when he died in 1935. Although his biggest films were not produced in Argentina, they nevertheless were hugely popular and contributed to the film industry in his home country, as imitations soon popped up. Throughout the latter half of the twentieth century, Argentine cinema has gone through several cycles of booms and busts, as political and economic instability have temporarily shut down studios. Currently, Argentine cinema is undergoing a renaissance and is known for edgy, intense dramas.
