Update:

101.1..

A hole is being drilled in a block of the Mg-Al alloy with a 10mm drill bit,at a feed of 0.2mm/rev,and with the spindle running N=800rpm and an average unit power of 0.5 W.s/mm^3 ,respectively.Calculate the material-removal rate and the torque on the drill.

Update 2:

101.2..

What differenees are the gravity permanent mold casting, high pressure die casting, and low pressure die casting, respectively?

Update 3:

99.1.

Explain the difference between recovery and recrystallization.

99.2

List and briefly explain the three mechanisms by which metals shrink during casting.
