SPMs are superior to computer numerical control (CNC) machines for producing large quantities of
similar parts; however, most manufacturers still rely on well-known CNCs for large volume production tasks. This is mainly attributable to the fact that both SPMs and CNCs incorporate high capital costs; SPMs are more productive and CNCs are more flexible. When the part in production is no longer in demand due to frequent market changes, SPMs become idle while CNCs can be easily reprogrammed for producing other parts. Yet the concluding statement could be different when modular SPMs are utilized.
