The total cycle time of an automatied fiber placement (AFP)operation (sheet lamination), used to manufacture a section of theairplane fuselage, is 8 hours and 40 minutes. The setup time beforethe start of the operation is 10 minutes. After each layer is putdown, an inspection stage is performed for 5 minutes. The AFP headrequires cleaning cycle of 3 minutes every 7 layers.
a. If the part is made of 20 layers, what is the time required(in minutes) to lay down 1 layer?
b. What is the percentage of down time for this operation?
c. What is the total cycle time (in minutes) for making thispart, if the lay down speed was doubled?
