Exercise 16, application In the problem15, suppose that a double gripper is used instead of a single gripper as indicated in that problem. The activities in the cycle would be changed as follows: Seg. Activity Time 1 Robot reaches and picks raw part from incoming conveyor 3.3 sec. in one gripper and awaits completion of machining cycle. This activity is performed simultaneously with machining cycle. 2 At completion of previous machining cycle, robot reaches 5.0 sec. in, retrieves finished part from machine, loads raw part into fixture, and moves a safe distance from machine. Machining cycle (automatic). 33.0 sec. Robot moves to outgoing conveyor and deposits part. This 3.0 sec. activity is performed simultaneously with machining cycle. Robot moves back to pickup position. This activity is 1.7 sec. performed simultaneously with machining cycle. Exercise 16 (cont.) Steps 1, 4, and 5 are performed simultaneously with the automatic machining cycle. Steps 2 and 3 must be performed sequentially. The same tool change statistics and uptime efficiencies are applicable. Determine the hourly production rate when the double gripper is used, taking into account the lost time due to tool changes and the uptime efficiency.
