In machining, what does the term kerf describe?

• A. The width of material removed by a cut
• B. The type of alloy used
• C. The speed of cut
• D. The feed rate

Answer: (A)

Kerf describes the width of material removed by a cut. It’s the gap carved out as the cutting tool moves through the workpiece. This matters for dimensions and yield: the finished width will be the stock width minus the kerf. The kerf is mainly determined by the cutting tool’s width (blade thickness or cutter diameter) and can be affected by blade wear or how the tool travels, but it isn’t about the metal type, cutting speed, or feed rate. So the key idea is that kerf is simply the width of material removed in the cut.
