Introduction of AFM
Precision and Ultra finishing process represents a critical and expensive phase of the overall production process. Manufacturing of precision parts consists a stage of final finishing operation. It is mostly uncontrollable, labour intensive and frequently involves a reasonable part of the total manufacturing cost. The functional properties such as wear resistance and power loss due to friction are influenced by surface roughness of the matching parts [1, 3].
To counter the problems such as high direct labour cost and to produce finished precision parts with specific features for finishing inaccessible areas, abrasive finishing techniques are developed. Abrasive finishing process is carried with large number of cutting edges which have indefinite orientation and geometry. Abrasive fine process are commonly employed due to their capacity of finishing various geometries of form (i.e. Flat, round etc.) with desired dimensional accuracies and surface finish [1, 6].
1.1 OVERVIEW OF TRADITIONAL FINISHING PROCESS:
Before discussing advanced finishing process, it is beneficial to understand the material removal mechanism commonly adapted in

AFM can be regarded as a process of generating a self –formingly tool that correctly removes the workpiece material and finishes those areas which are restricted to the medium flow. AFM technique is used for deburring, edge contouring and surface finishing. It is capable of finishing regions which are difficult to reach by flowing abrasive by mixing with polymer of special rheological properties. AFM produces uniform, repeatable and predictable results on a notable range of finishing operation. Normally the properties of carrier in AFM process play an important role. They should be visco-elastic and non-sticky in nature. Aluminium Oxide, Silicon Carbide, Boron Carbide and Diamond are commonly used abrasive grains in AFM process
Unknown 6- Isopropyl Alcohol We found that unknown 6 was Isopropyl alcohol. Its chemical name is isopropanol and the chemical formula C₃H₈O but is typically called isopropyl alcohol. Isopropyl alcohol is today used as a primary ingredient in rubbing alcohol. Is smells very unpleasant and is used for disinfecting pads used by medical professionals for tasks such as sanitizing small instruments, wiping down surfaces, and cleaning a patient’s skin before an injection.
These days technology is such a big party of daily life that people often take their devices with them as they go about their day. If you have to stay in touch with work, or family, it may become necessary to charge these devices while you in the car. A 3 amp 12 volt car USB port makes this possible. Amazon has a variety of charging ports for your car or truck. Choose one to help you stay connected no matter where you are.
Unit 1 Process Based Essay “The Tell-Tale Heart” by Edgar Allen Poe The characteristics of insanity is shown through one's actions, such as them saying things they shouldn't or doing things that sane people wouldn't. This is a story about an insane man who is trying to convey the audience that he is not insane. In “The Tell-Tale Heart”, Edgar Allen Poe utilize symbolism and point of view to reveal that one's insanity can be characterized by their intellect and erratic actions.
Perfectionism has been in my blood since I was a young kid always lining up my toy tractors against the wall in order of size or color. I have always had this burning passion in me that I need to do more; achieve more. Looking at the long list of activities and causes I dedicate my time to has been an eye opener. I am the busiest person I know but it doesn’t always appear that way to me.
In my Avid class we have been doing the quizzes that determine what we understand, find confusing, and our personality. By doing this we have found what we are good at and how we will succeed. Since this is my first year of high school, I can apply my strengths into my systems to have a postitive result. I have three systems: school (#1), home (#2), and sports (#3).
Unbroken is a biography by Laura Hillenbrand about Louie Zamperini’s entire life. Louie Zamperini is a son of Italian Immigrants that moved to Torrance, California. He starts out as a problem child that would steal, drink and smoke, but he eventually straightens out through sports and became an Olympian later in life. After he went to the Olympics, he gets drafted into World War 2.
Jack Ma once said, “The world needs new leadership, but the new leadership is about working together.” This could not be more true at Boston University through its Kilachand Honors College. I believe it is because their approach of interdisciplinary problem-solving, is about expanding students’ world-views. In this program you are learning with different individuals who have different interest and fields of study. According to Pew Research Center, “Political polarization is the defining feature of early 21st century American politics...”.
• CG 4.1 How do you ensure that families are kept aware of what 's happening in their child 's daily/weekly life in your program? I make sure that families are kept aware of their child’s life on a daily and weekly basis by providing them with the information from their child’s day on a daily report. I also make sure that I communicate with them both positive and negative things are their child’s day. I want to keep a healthy relationship between myself and the child’s parents and to do so I need to communicate with them about their child’s day.
Writing process is difficult to realize since it requires a lot of skills and knowledge. Definitely, not many of us can start writhing right away without having any problems such as grammar, vocabulary or organization. However, a person can become a better writer if he or she will practice writing every day and will pay attention to his writing problems. To become a good writer, I have to improve my grammar, follow specific steps in writing process, and avoid using similar transitional words. Grammar is the number one problem in the writing process and causes me a lot of issues.
I am competitive; I look for the chance to run the extra mile. My competitive nature has aided in everything I commit myself to. Regardless if I am participating in a sporting event, competing for a solo in a musical production, or preparing for a final, I will indubitably devote my time and efforts to perform as well as possible. I take every opportunity that is presented to me and attempted to better not only myself but my community as well. I am confident that the Honors College at the College of Charleston will enable me to devote my attention to my studies, become actively involved within campus activities and academic assemblies, and offer my time and abilities to charitable events and organizations.
Every student has their own writing process. Writing process ways is the student's way to have the best writing assignments and make who ever read it understand their main idea. In this essay I am going to explain my own writing process for various type. In chapter 4 by Keith Hjortshoj “How Good Writing Gets Written” which talks about how should develops their writing skills and gives them some tips that they should use in their writing process.
There are people in this world who always seem to strive for perfection. A perfectionist is basically a person who who has extremely high standards, a person who believes that there is no room for mistakes, that everything must be flawless. So anything that is less than perfect is absolutely unacceptable. Are you a perfectionist? Here are a couple of signs of perfectionism you should know.
In school, things can get pretty rough. There is a bunch of homework, tests, and lots of other things that can stress a student out. A student needs to find some sort of process that works for them. They need to be organized, so everything is laid out in front of them. Getting organized, and preparing yourself is a great way to get great grades in school.
It is not an uncommon occurrence for a parent to approach me to ask me about the methods I use to get good grades. They always seem to assume I dedicate countless hours to formulating study guides and reviewing material. They believe the only way to reach “my level” is to sacrifice sufficient sleep and a social life. This, however, cannot be further from the truth. I earn my good grades without sacrificing other important aspects of my life by planning ahead, collaborating, and using efficient study methods.
In the first year of my graduation, the subject of workshop technology was offered which helped me to understand the basics of manufacturing. It involved study and working on machines like Lathe, Milling, Universal Grinding Machine, and other specific machinery. In later stage of my graduate programme, I
