A horizonal milling conducted on a mild steel plate of a biomedical device is shown in the right figure. We know that the constant k = 1, cutting speed V=50 ft/min, cutting tool diameter D = 2 in, feed per cutting tool tooth ft = 0.004 in/tooth, number of cutting tool teeth n= 12, cutting length on sample L = 20 in, cutting depth t = 0.5 in, cutting width W= 1 in, please compute the following milling parameters: a) The milling speed N, with unit of rpm. b) The sample feed rate fm. c) The approach length of cutting tool LA. d) The cutting time Teut, please do not ignore LA. e) The material removal rate MRR, please ignore LA.
