🔍 Key Concepts

• Look closely at the orientation of the cutting edge of tool Q in relation to the workpiece and the lathe centers. • Review how a cutting‑off (parting) tool looks compared to facing and turning tools in a standard lathe-tool chart. • Recall the difference between right‑hand and left‑hand turning tools: which direction they are designed to feed along the work (toward the headstock or toward the tailstock).

💭 Think About

• Does tool Q appear narrow and straight for cutting directly into the diameter, or does it have a side-cutting edge meant to travel along the length of the work? • If the carriage were to move in the normal longitudinal feed direction, would tool Q remove metal along the side of the work (turning) or across the end (facing)? • Based on the shape of tool Q, in which direction along the shaft could it advance while keeping the cutting edge leading: from right to left, or from left to right?

✅ Before You Answer

• Verify whether tool Q’s cutting edge is on the side or on the extreme tip; a parting tool mostly uses its tip, while a turning tool uses its side edge. • Check if tool Q is positioned to work on the cylindrical surface (turning) rather than the end face (facing) of the workpiece. • Confirm from a standard lathe-tool diagram which way a right-hand turning tool is fed versus a left-hand side facing tool, then match that to the visible orientation of tool Q.
