PRIME ELEMENTS MACHINE DESIGN II

1. Heating above the transformation range, usually 1300oF to 1350oF, and cooling slowly to soften the metal and increase in machining A. annealing B. hardening C. normalizing D. tempering 2. Heating above the transformation temperature and quenching usually in oil, for the purpose of increasing the hardness A. annealing B. hardening C. normalizing D. tempering 3. Reheating to temperature below the transformation range, followed by any desired rate of cooling to attain the desired properties of the metal. A. annealing B. hardening C. normalizing D. stress relieving 4. Heating to subcritical temperature, about 1100oF to 1300oF and holding at that temperature for a suitable time for the purpose of reducing internal residual stresses. A. annealing B. hardening C. normalizing D. stress relieving 5. Heating some 100oF above the transformation range with subsequent cooling to below that range in still air at room temperature to produce uniform structure of the metal. A. annealing B. hardening C. normalizing D. tempering 6. A machine tool used for producing holes in metal by the use of cutting tool called drill.

A. drilling machine B. boring machine C. milling machine D. broaching machine 7. A machine tool use to form metal parts by removing metal from a work piece By the use of a revolving cutter with many teeth each tooths having a cutting edge which removes its share of the stock. A. drilling machine B. boring machine C. milling machine D. broaching machine 8. A machine tool used to sharpen or shape tools by using an abrasive wheel. A. tool grinder B. shaper C. planer D. power saw 9. A machine tool used to enlarge a hole by means of an adjustable cutting tool with only one cutting edge. A. drilling machine B. boring machine C. milling machine D. broaching machine 10. A machine tool used to cut metal by parts of light, medium, and large sections using a reciprocating hacksaw blade. A. tool grinder B. shaper C. planer D. power saw 11. A machine tool used to machine flat or plane surfaces with a single point cutting tool. A. tool grinder B. shaper C. planer D. power saw 12.
