Manufacturing process decisions. How do we choose the specific manufacturing processes How do the selected materials influence the choice of manufacturing processes Would product function or performance issues influence our choice of processes What criteria should we use to select processes Which criteria are more importantWho will make the final decisions Parts undergo sequence of processes.
