MAE 272 Exam 1 Questions and Answers
Graded A+
Which are NON-traditional joining processes Laser and EB welding
Draw beads are occasionally used for: In deep drawing to control metal flow and flange
forming
Temperature built up during machining Will shorten tool life
Riser: helps reduce impurities, shrinkage, and porosity in the casting
break even point: useful when comparing different manufacturing and dependent on
ordered quantities
Not required to produce 3 piece can: Punching
, hot tears caused differences in cooling rates due to differences in local surface to volume
ratio
ball bearing balls produced cost effectively by Cross rolling
Return on Investment: Depends on quantity ordered
minimum bend radius: depends on the rolling direction of the metal before bending
In sheet metal fab, anisotropy can: Cause variations of properties in different directions
Risers help: None is correct
SPC means Quality inspection at predetermined but revisable sampling rates and sizes
Threaded base of the light bulb produced cost effectively by: none of the above
Anisotropy in sheet metals: can cause dog-ears and non-uniform wall thickness in deep
drawing
