ABSTRACT
Manufacturing processes have and will continue to evolve in the years to come due to the ever-increasing needs of various industrial sectors. These processes can be broadly classified into three major categories, i.e., subtractive, additive, and hybrid. Subtractive methods allow for the manufacture of products by successively removing material from a solid block, whereas additive methods are the exact opposite, and they build products by laying down layers of material on top of each other. Less waste and design flexibility are two of the most important advantages of additive over subtractive. Computer numerically controlled machining is a prominent example of subtractive manufacturing, whereas a number of processes fall under the umbrella term of additive manufacturing. Amid this competition, hybrid methods have joined the race as well to provide effective manufacturing solutions. Hybrid provides a unique combination of a number of different processes such as additive, subtractive, joining, and transformative. This chapter aims to discuss the aforementioned manufacturing processes and associated types pertaining to their suitability for the manufacture of various products.
