Final answer:
The true statement about manufacturing processes is that 'Subtractive manufacturing is a traditional manufacturing process.'
Step-by-step explanation:
Subtractive manufacturing involves the removal of material to create a final product. Common subtractive processes include cutting, milling, and turning. It is considered one of the traditional manufacturing processes.
In contrast, additive manufacturing, which includes techniques such as 3D printing, is a newer manufacturing process that involves adding material layer by layer to build a product.
Smart manufacturing refers to the use of interconnected technology and advanced analytics to improve the manufacturing process. It is not a traditional process but rather a contemporary approach that combines information, technology, and human ingenuity to bring about a revolutionary change in the manufacturing industry.
