Q

If you are cutting off a piece of stock in a lathe and the work piece tends to climb over the top of the cutoff tool, you should __________.

🔍 Key Concepts

• Lathe cutoff (parting) operations and how forces act on the tool and work piece • Effect of tool height (above, at, or below centerline) on cutting forces and tendency to climb • Conditions that actually cause the work piece to move in the chuck vs. conditions that change cutting action

💭 Think About

• Think about what happens to the cutting force if the tool is set too high or too low relative to the centerline of the work. • Ask yourself which action directly changes the cutting geometry at the point of contact, rather than just changing speed or general setup. • Consider which choice would reduce the tendency of the work to ride up over the tool, instead of just treating symptoms like slipping or friction.

✅ Before You Answer

• Verify which adjustment affects vertical cutting force direction at the tool tip (upward vs. downward). • Check which options require you to stop the lathe and whether that alone would change the climbing tendency. • Confirm whether increasing spindle speed would make the work piece more or less likely to climb over the tool.
