What is typically the last step in a lathe operation?

In lathe operations, the last step is typically the cutoff. This process involves severing the workpiece from the remaining stock or material that is held by the chuck or spindle. Once the primary machining operations have been completed—such as turning, threading, or drilling—the cutoff ensures that the finished part is separated cleanly and precisely, leaving a finished edge.

Choosing cutoff as the last step is integral to achieving a complete and usable part. This final operation not only helps in completing the manufacturing process but also minimizes potential damage to the finished surface of the part which could occur if subsequent operations were performed afterward. By executing the cutoff at the end, a machinist ensures that they have a fully finished part ready for inspection or use.
