The process described involves transforming raw rolled stock into discrete products-bearings-by stamping them at Station A.
This is characteristic of a discrete process (D), where distinct, countable items are produced (bearings), typically involving individual units or assemblies.
Batch processes (C) involve processing material in defined lots or batches, but the emphasis here is on individual item production.
Continuous processes (B) run nonstop with materials continuously flowing, common in chemical plants but not in stamping.
Distributed (A) refers to control architecture rather than process type.
GICSP defines discrete manufacturing processes as producing distinct items, requiring specific cybersecurity considerations around control logic and equipment.
