Non-Traditional Machining

The quiz will be graded for accuracy, so take time to seek the correct answers for this study guide before you attempt the quiz. Once you start the quiz, do not exit the quiz until the entire quiz is completed. Exiting out of the quiz before it is complete may result in a zero

Part I. Each question is worth 3 points. For multiple choice questions, use highlight or bold to mark your answers.

Points:  5 questions at 40 points each for 200 points for 25% of your grade (all will be sliding scale).

Section A: Answer all questions. Total 42 points – each question in this section carries 3.5 points. Write the responses to ALL questions in your answer sheet.

Note: The following six questions are weighted equally; each will count as one-sixth of your overall test grade.

Type the letter that represents the best answer to each of the multiple choice questions. Answer all questions in this section. Each question is worth 1 point.

Question #1 is worth 5 points – all others are worth 1 point each. Either type your answers directly onto THIS sheet OR create a new file and number your answers 1, 2, 3, etc.

There are 15 questions – Questions 1-9 are worth 3 pts; questions 9-14 are worth 4 pts and Question 15 is worth 5 points.

After I had taken the quiz, my results came out that I had answered 6 correct and 14 incorrect; receiving a total score of 30%.

Please complete these questions in groups of 2, to hand in. The grade is calculated as part of your participation grade, so participation, as with the last case, can improve your score substantially, even if your calculations aren’t all perfect!

NC Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools. Tools that can be controlled in this manner include lathes, mills, routers and grinders. The CNC in CNC Machining stands for Computer Numerical Control. On the surface, it may look like a normal PC controls the machines, but the computer's unique software and control console are what really sets the system apart for use in CNC machining. Under CNC Machining, machine tools function through numerical control. A computer program is customized for an object and the machines are programmed with CNC machining language (called G-code) that essentially controls all features like feed rate, coordination, location

Abrasive Jet Machining (AJM) is the removal of material from a work piece by the application of a high speed stream of abrasive particles carried in gas medium from a nozzle. The AJM process is different from conventional sand blasting by the way that the abrasive is much finer and the process parameters and cutting action are both carefully regulated. The process is used chiefly to cut intricate shapes in hard and brittle materials which are sensitive to heat and have a tendency to chip easily. The process is also used for drilling, de-burring and cleaning operations. AJM is fundamentally free from chatter and vibration problems due to absence of physical tool. The cutting action is cool because the carrier gas itself serves as a coolant and takes away the heat.

Today I will be talking about the research I did on quick change methodology. This is a very fascinating and important topic for the machining process in all plants across the world. The topics that will be covered in this paper are as follows defining quick change methodology and tooling for machining with an overview history and recent advancements, SMED overview history and recent advancements, then a compare and contrast of quick change methodology and SMED, and to wrap up the paper I will illustrate how I can use this information to improve a manufacturing process I am familiar with. These were great research topics and I learned a ton of great valuable information that would be very useful in future endeavors.
