Shaping process differ from a surfce processing operation?

Shaping processes involve the removal of material from a workpiece to create specific geometric forms, typically using cutting tools, whereas surface processing operations focus on enhancing the surface characteristics of a material, such as texture, finish, or hardness. Shaping can produce complex shapes and profiles, while surface processing aims to improve attributes like corrosion resistance or aesthetic appeal. Essentially, shaping alters the overall geometry, while surface processing modifies the surface quality without significantly changing the underlying shape.
