Abstract: Aircraft components are produced using precision manufacturing processes like turning, milling, drilling, jig boring, grinding, polishing, etc. in multiple setups. Increase in tolerance stackup, large in-process inventory, requirements of several jigs and fixtures and large cycle time are the problems encountered in the aircraft component manufacture. Multi-tasking machines offer a convenient solution for this problem by limiting all the operations to a single multitasking machine. This study has been carried out to quantify techno-economic benefits of multi-tasking machines. Some typical general system components like cover, housing, valves, etc. have been taken for investigation. Alternate machining strategy using multi-tasking machines have been proposed. An attempt has been made to compare between the multi-machines and multi-tasking machines in terms of time, cost, number of setups involved, etc. for the manufacture of aircraft components.
