Answer:
Option D: Dog with dog plate
Explanation:
A lathe dog, also known as a lathe carrier, is a device that clamps around the workpiece and allows the rotary motion of the machine's spindle to be transmitted to the workpiece. A carrier is most often used when turning between centers on a lathe, but it may be used on dividing heads or any similar situation.
Answer:
d. Dog with a dogplate
Explanation:
A lathe dog is used when you are working on the live center being the spindle and the dead centre being the tail stock, a lathe dog with a dogplate is mounted to the headstock which tightened the workpieces at one end, and then engages the slot at the other end of the plate to transmit the torque that drives the lathe dog and the workpiece.
Therefore the lathe dog is used to transfer the torque from the spindle to the workpiece.
