1、Largent est le nerf de la guerreFilomeno MartinaScope To compare the cost of a part made by WAAM vs traditional machined from solid To assess the sensitivity of cost to changes in key cost drivers / process parameters: Deposition rate Buy to fly ratio Material cost Machine cost Capacity utilisation
2、Material removal rateMachining from solid Cost model terms: Mass of initial forging or billet cost of initial forging Buy to fly ratio material to be removed Material removal rate machining timeWAAM Cost model terms: Mass of substrate cost of substrate Buy to fly ratio material to be deposited, and
3、to be removed Deposition rate + Starts if If WAAM machine cost 250k SS = 1.5 to include rolling Plate /kg = Billet /kg Only 1 type of machining operationSpecific costs / performances Unless specified differently: Cost of machine: 180k Depreciation: 5 years Utilisation: 80% Labour cost: 45/h WAAM hou
4、rly rate = 82/h Cost of wire: 130/kg Cost of forging: 60/kg Deposition rate: 1 kg/h Material removal rate: 8 kg/h (accounts for complexity) Machining hourly rate: 60/h Cost of inspection: 1000 To transfer to other materials, change: Deposition rate, cost of raw materials, material removal rateRESULTSPart costf(BTF, mass)Part costf(BTF, mass)Part costf(BTF, mass)
