Concept explainers
(a)
Suggest one or more nontraditional machining processes that might be used and present arguments to support your choice for a matrix with holes 0.1 mm (0.004 in) in diameter in a plate of hardened tool steel 3.2 mm (0.125 in) thick.
(b)
Suggest one or more nontraditional machining processes that might be used and present arguments to support your choice for an engraved aluminum printing plate to be used in an offset printing press to make 275 by 350 mm (11 by 14 in) posters of Abraham Lincoln’s Gettysburg Address.
(c)
Suggest one or more nontraditional machining processes that might be used and present arguments to support your choice a through-hole in the shape of the letter L in a plate of glass 12.5 mm (0.5 in) thick. The size of the “L” is 25 by 15 mm (1.0 by 0.6 in) and the width of the hole is 3 mm (1/8 in).
(d)
Suggest one or more nontraditional machining processes that might be used and present arguments to support your choice for a blind hole in the shape of the letter G in a 50-mm (2.0-in) cube of steel. The overall size of the “G” is 25 by 19 mm (1.0 by 0.75 in), the depth of the hole is 3.8 mm (0.15 in), and its width is 3 mm (1/8 in).
