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 __________.

Correct Answer: Option C — increase the height of the tool cutting edge

If a cutoff tool is set too high, the rake angle becomes ineffective, causing the tool to ride up on the work rather than cutting into it. Lowering the tool height to the centerline of the workpiece ensures the cutting edge engages properly, preventing the tool from climbing and potentially breaking.
