The term used for the material removed from a workpiece during machining is swarf. This term encompasses the shavings, chips, or debris that are produced when a cutting tool interacts with the material being machined. Swarf can vary in form depending on the material being cut and the machining process used, and it is important to manage swarf properly to maintain a clean working environment and ensure the efficiency of the machining operation.

The other terms listed do not refer to the removed material. "Cast" refers to a manufacturing process where liquid material is poured into a mold and allowed to solidify, thus forming a shape. "Fillet" describes a rounded transition between two surfaces in a machining or fabrication context, typically to reduce stress concentrations. "Extrusion" is a manufacturing process where material is pushed through a die to create a specific cross-sectional profile. Understanding these distinctions is crucial for someone working in machining and helps in grasping the broader concepts of manufacturing processes.
