Question
Chapter 21, Problem 73SDP
To determine
Experiments have shown that it is possible to produce thin, wide chips, such as 0.08-mm (0.003-in.) thick and 10-mm (4-in.) wide, which would be similar to the dimensions of a rolled sheet. Materials have been aluminum, magnesium, and stainless steel. A typical setup would be similar to orthogonal cutting, by machining the periphery of a solid round bar with a straight tool moving radially inward. Describe your thoughts regarding producing thin metal sheets by this method, taking into account the metal’s surface characteristics and properties.
