🔍 Key Concepts

• Function of the dead center on a lathe and how it supports the work piece • Standard machining preparation of a shaft end before mounting between centers • Difference between boring, tapering, drilling, and shaping (convexing) the end of a work piece

💭 Think About

• Which choice prepares a small, accurate locating feature exactly on the axis of the work piece? • Which operations mainly change the outside shape, and which create an internal locating point or hole? • What does the dead center actually contact on the work piece when it is supporting it in the lathe?

✅ Before You Answer

• Make sure you know that a dead center supports the work on its axis in the headstock or tailstock • Identify which process makes a conical seat or recess for the lathe center to fit into • Eliminate any option that mainly changes the outside profile instead of providing an internal locating seat for the center
