Transfer Automated Production Lines
Automated Production Lines multiple workstations linked by work handling system transferring parts between stations (in cycles-same to manual), conditions for automated line, high product demand--quantities stable product design--frequent design changes long product life >1 year multiple operations on product benefits, low: direct labor content product cost because cost of fixed equipment (spreaded over units) Minimize: production lead times, WIP, factory floor space high: production rates Palletized vs. Free transfer line- avoid cos t Pallet Fixtures ->accurate workholding device ->fixtures part in a location to be moved ->clamped in position at successive workstations by transfer system Work Flow system configurations 1. in-line : a sequence of stations in a straight line machining big work pieces 2. segmented in-line : >1 straight line transfer sections, segments perpendicular to each other , allows reorientation of work piece for dif
