Which manufacturing process is characterized by forming parts without creating chips?

The process that is characterized by forming parts without creating chips is known as forming. This manufacturing technique involves altering the shape of materials through processes such as bending, stamping, forging, and extrusion. These methods manipulate the material's structure without removing any of it, thus avoiding the production of chips or waste typically associated with machining processes.

In contrast, machining processes, such as milling, involve the removal of material to achieve the desired shape and size, resulting in chips as a byproduct. Finishing processes typically follow machining to enhance surface quality or other characteristics, but they also often involve additional material removal. Therefore, forming stands out as a method that focuses exclusively on shaping material without chip generation, highlighting its efficiency in certain manufacturing applications.
