The air set sand casting process involves the preparation of a mixture of sand and a chemical binder. Unlike traditional green sand casting, which uses moisture in the mold, air set sand casting relies on a two-part chemical binder system that hardens when mixed with sand. This mixture is often placed into a mold box, where it is shaped around a pattern that represents the object to be cast. Once the mixture cures, the pattern is removed, creating a mold cavity.

Turning is a machining process where a cutting tool removes material from the outer surface of a rotating workpiece. This is typically performed on a lathe, where the workpiece is held securely while the cutting tool moves linearly or radially. Turning is primarily used to create cylindrical parts, such as shafts, pins, and bolts. Variations of turning, including facing (creating flat surfaces on the ends of parts) and taper turning (producing conical shapes), are also common.
