What does the term "chip" refer to in machining?

The term "chip" in machining specifically refers to the small pieces of material that are removed from the workpiece during the cutting process. When a cutting tool interacts with the material, it displaces some of the workpiece material, which then shears off in the form of chips. This removal of material is essential for shaping the workpiece into the desired form and dimensions.

In machining, the size, shape, and type of chips produced can give valuable information about the machining process, such as the effectiveness of the cutting tool, the type of material being machined, and the conditions under which the machining is taking place. Understanding chip formation helps machinists optimize cutting parameters, tool selection, and workpiece materials for improved efficiency and quality in the machining process.
