- An articulated robot loads and unloads a CNC machine tool. The cell is scheduled to produce abatch of 300 parts. Setting up the cell for this part style takes 30 min, programming the robot takes75 min, and programming the CNC machine tool takes 55 min. For safety reasons, these threesetup activities must be done sequentially. The programmed machining cycle takes 3.75 min.Cutting tools wear out and must be periodically changed, which takes 6.0 min every 20 cycles andis performed by a human worker. At the end of each machining cycle, the robot reaches into themachine and removes the just-completed part, places it in a parts storage carousel, then reachesfor a starting work part from the same carousel and places it in the machine tool fixture. Thissequence of handling activities takes 45 sec. The storage carousel holds 25 parts. At the beginningof the production run, it is full of raw work parts.
