Sculpture is a form of plastic art, a visual art that creates three-dimensional spatial images through the use of material and means. Early sculptures were primarily created using carving (by removing material to shape) and modeling (by adding material to shape), working with materials such as stone, metal, wood, and ceramics. However, modernist sculpture has a high degree of freedom in both materials and creative techniques, allowing for the use of carving, welding, molding, or casting on various different materials.

The designed process specifications should ensure the machining quality of machine parts (or the assembly quality of the machine) and meet all the technical requirements specified in the design drawings.

(2) The process should be highly productive to expedite the product launch into the market.

(3) Efforts to reduce manufacturing costs

(4) Be mindful of reducing the labor intensity for workers.
