What determines the distance traveled by a lead screw with one complete rotation?

The diameter of the screw
The pitch of the screw
The material composition of the screw
The type of motor used

The correct answer is: The pitch of the screw

The distance traveled by a lead screw with one complete rotation is determined by the pitch of the screw. The pitch is defined as the distance between adjacent threads. Thus, when the screw makes a full rotation, it moves linearly along its axis by a distance equal to its pitch. This relationship is crucial for applications involving linear motion in CNC machinery, as it directly affects the precision and accuracy of the movement achieved by the lead screw. The diameter of the screw does not affect the distance traveled per rotation; it influences the strength and stability of the screw but is not a factor in how far the lead screw moves with one complete turn. The material composition can affect the durability and performance of the screw, including how well it can handle loads or resist wear, but it does not play a role in the distance moved per rotation. Likewise, the type of motor used may affect the speed or force applied to the screw, but it does not determine the linear distance moved during one complete turn.
