MAE 272 EXAM 1 AND EXAM 2 Questions
and Answers 100% Solved
fine vs conventional blanking fine blanking requires more precise and expensive tooling
and it produces a smooth shear surface albeit burr
spring back in sheet metal forming is a function of E modulus, yield strength, sheet
thickness, and bending used
hot forming of metals is carried out at t/tm>0.06
flat rolling can be used to produce coils for aluminum cans
hot tears in castings are called difference in cooling rates due to a
difference in surface volume ratios
astm b211 making on the a606-1 in hex rod indicates precision extruded profiles
, climb milling is preferred for slender parts due to the downward forces
connecting rods in internal combustion engines are designed to convert a linear motion
into an angular one
not required for electrical cars
angles such as chamfers can be measured by using none of the above
annealing is a thermal process applied to a cold-worked metal to restore its properties and
grain structures
the letter t in aa6061-t6511 means strain hardened crystal structures
when measuring the dimensions and/or form deviations of an extremely accurate part
temperature ,must be controlled for tools, workpieces, and surroundings
on a turret lathe, the following parts can be produced with a single set up male and female
threads
