A six-station dial-indexing machine is designed to perform four assembly operations at stations 2 through 5 after a base part has been manually loaded at station 1. Station 6 is the unload station. At each of the four assembly stations, a hopper-feeder is used to deliver components to a selector device that separates components that are improperly oriented and drops them back into the hopper. The system was designed with the operating parameters for stations 2 through 5 as given in the table below. It takes 2 sec to index the dial from one station to the next. When a component jams, it takes an average of 2 min to release the jam and restart the system. The line manager says the production system was designed to produce at a certain hourly rate, which considers the jams resulting from defective components. However, the actual delivery of finished assemblies is far below that designed production rate.
