🔍 Key Concepts

• Lathe tool functions: turning, forming, parting/cutting off, and profiling • How the cutting edge is shaped compared to the final shape you want on the workpiece • The tool’s width and orientation to the workpiece axis

💭 Think About

• Look closely at tool M’s shape: is it narrow and straight, or does it copy a specific contour? • Ask what operation this tool would perform on the rotating work: remove material along the length, cut a groove, separate a piece, or create a curved profile? • Compare tool M to the tools labeled along the rest of the shaft—how is its job different from those doing general turning or shaping shoulders?

✅ Before You Answer

• Verify where tool M is positioned relative to the end of the workpiece and chuck jaws • Check whether tool M’s cutting edge is designed to produce a specific profile in one pass or simply to slice straight into the work • Confirm if the tool’s blade is narrow and used radially (straight in toward the center) rather than fed along the length of the shaft
