Before power to a lathe is turned on, it is a good shop practice to first hand feed the carriage to ensure _______________.
AI Explanation
The correct answer is C) all locking devices have been released.
Before turning on power to a lathe, it is a good shop practice to first hand feed the carriage to ensure that all locking devices, such as the carriage lock, compound rest lock, and tailstock lock, have been released. This allows the carriage to move freely and prevents any potential damage to the lathe or work piece when the power is turned on. The other options, while important considerations, do not directly address the need to ensure the locking devices are released before starting the lathe.
