IND 115 Final Exam Fall 2022 Name _Maleek Goodman___________________ Professor Pruden 1. Name the four (4) methods in which a work part can be held in an engine lathe. Between centers, chuck, face plate, and collet 2. Identify three desirable properties of a cutting-tool material. Toughness, hot hardness, and wear resistance. 3. Abrasives commonly found in nature include all of following except: A. Emery B. Garnet *typo maybe? all are natural. C. Quartz D. Garnet 4. The following are finishing operations except: A. Honing B. Superfinishing C. Lapping D. Barreling 5. Name the two (2) reasons for using cutting fluid in a machining operation. To flush away chip pieces from cutting zone and for lubrication 6. Define machinability. Machinability is the ease with which a given material may be worked with a cutting tool. 7. What does the heat treatment of metals process involve? the use of heating or chilling, normally to extreme temperatures, to achieve the desired result such as hardening or softening of a material. 8. Name the five (5) joint types in joining two metal plates or wooden boards. Butt, corner, T, lap, and edge joints.

9. Electrode coating functions include all of these except: A. To Provide Deoxidizers & Scavengers B. To Increase Deposit Rates C. To Minimize Gases D. To Produce a Slag Covering E. To Provide Mechanical and Physical Properties 10. Describe the submerged-arc welding (SMAW) process. Submerged arc welding is an arc welding process in which metals are joined using an electrical arc established between a continuous fed bar metal consumable electrode or electrodes and the work. 11. List five (5) methods of mechanical assembly that allow for easy disassembly. Threaded fasteners such as nuts, bolts, and screws, anchors, and rivets. 12. Identify five (5) advantages of adhesive bonding compared to alternative joining methods. 1. Process is applicable to a wide variety of material, 2. Parts of different sizes and cross sections be joined,3. Bonding occurs over the welding, 4. Some adhesives are flexible after bonding and are thus tolerant of cuclical loading and differences in thermal expansions, 5. Low temp curing avoids damage to parts being joined 13.The soldering process shown here

Can be described how? 2 different metals are welded with soldering 13. Material handling in manufacturing operations is usually associated with activities that occur inside a facility and not with transportation between facilities involving rail, truck, air, or waterway delivery of goods: TRUE FALSE 14. Automated 100% inspection can be integrated with the manufacturing process to accomplish which TWO of the following. (CIRCLE) (a) better design of products (b) feedback of data to adjust the process (c) 100% perfect quality (d) sortation of good parts from defects 15. Which one of the following is an example of contact inspection? (CIRCLE) (a) coordinate measuring systems (b) machine vision c) radiation techniques (d) scanning laser systems (e) ultrasonic techniques 16. Statistical Process Control (SPC) involves using various statistical methods to assess and analyze variations in a process. One tool is a control chart. What does a control chart show? show how a process performs over a period of time 17. What is Six Sigma in relation to quality assurance? Six Sigma is a quality management methodology used to help businesses improve current processes, products, or services by discovering and eliminating defects.

18. Review the Stress-Strain diagram below. Identify the point on the diagram that engineers use as a maximum anticipated load on a structure’s components. (CIRCLE) Ultimate strength 19. What five (5) advantages of cold working have over hot working? (1) better accuracy, (2) better surface finish, (3) increased strength due to work hardening, (4) possible directional properties due to grain flow, and (5) no heating of work required. 20. How is hardness rating determined in metals? The rockwell test 21. Anything over 10 secs is good for transitioning from Austinite to Pearlite T/F

22. Gussets, Islands, shelfs and ceilings are all support structures for rapid prototyping? T/F true 23. Anodizing is an electrolytic treatment that produces an oxide layer on a metallic surface. Applications include: A. Zinc B. Titanium C. Magnesium D. All of the above E. None of the above 24. Define nanotechnology. Nanotechnology is a field of research and innovation concerned with building 'things' - generally, materials and devices - on the scale of atoms and molecules.

25. What is a polymer? a long molecule consisting of many similar or identical building blocks linked by a dehydration reactions. 26. What Circuitization Method is shown below? 27. What is unique about a thermoplastic polymer? They can be melted and reformed multiple times before they start to lose their strength and integrity. 28. What percentage of iron must be in iron ore for it to be profitable to mine? 60% 29. Identify the process used to produce aluminum. Smelting Hall-Heroult process 30. Define tolerance in relation to dimensions and surface flatness of work pieces. A tolerance is an acceptable amount of dimensional variation that will still allow an object to function correctly. 31. How are nongraduated measuring devices used in determining the dimensions of a work piece? Non-graduated measuring devices are used to make comparisons between dimensions or to transfer a dimension for measurement by a graduated device.

41. A quality assurance program guarantees that all products made will be 100% perfect and without flaws. TRUE FALSE 42. Quality of products sold or distributed is a manufacturing “holy grail” that will make future sales more plausible and possible. TRUE FALSE 43. Describe the true value on the pictures below a,b,c in terms of accuracy and precision. a. the true value is accurate but not precise. That’s why the true value is in the middle if the curve. so large number of values fall in the accurate region. but since the variance is large the precision is less. b. The values are more precise but not accurate. We can see the true value falls in large distance from the mean. so, it shows the value measured is not accurate but more precise due to small variance. c. the values are more precise and accurate. since mean coincide with the values are more accurate and the variance is very low, so the values are more precise.
