Question:

A hard aerospace aluminum alloy is to be ground. A depth of 0.003 in. is to be removed from a cylindrical section 8 in. long and with a 3-in. diameter. If each part is to be ground in not more than one minute, what is the approximate power requirement for the grinder? What if the material is changed to a hard titanium alloy?
