The dial indexing machine of Problem 18.2 experiences a breakdown frequency of F = 0.06. The average downtime per breakdown is 3.5 min. Determine (a) average production rate in pieces per hour and (b) line efficiency.
Problem 18.2
A Geneva with six slots is used to operate the worktable of a dial indexing machine. The slowest workstation on the dial indexing machine has an operation time of 2.5 sec, so the table must he in a dwell position for this length of time. (a) At what rotational speed must the driven member of the Geneva mechanism be turned to provide this dwell time? (b) What .s the indexing time each cycle?
