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 _______________.
AI Explanation
The correct answer is C) increase the height of the tool cutting edge.
When a workpiece tends to climb over the top of the cutoff tool, it indicates that the tool cutting edge is positioned too low relative to the centerline of the workpiece. Raising the height of the tool cutting edge will provide more clearance and prevent the workpiece from climbing over the top of the tool. This adjustment helps maintain proper tool geometry and cutting conditions for a clean, controlled cutoff operation.
The other options are incorrect because: A) stopping the lathe and tightening the chuck does not address the issue of the tool position, B) increasing the spindle speed may not resolve the climbing issue, and D) stopping the lathe and lubricating the dead center is unrelated to the problem at hand.
