Answer:
Lathe-turning, milling, drilling, sawing, thread-cutting and gear-cutting are some examples of subtractive processes involving metal-cutting that are traditionally carried out in specialized machines.
Explanation:
Subtractive processes involve removing material from a solid block of starting material. Machining, milling, and boring are all subtractive processes that create or modify shapes. ... Solid deformation processes, like all forming operations, involve flow, shape definition, and shape retention.
