Travel per turn is another way to express the feed in lathe operations.

Explanation:
In turning, feed is how far the cutting tool moves along the workpiece axis with each complete turn of the spindle. Travel per turn means the same idea: the distance the tool advances for one revolution of the work. So, travel per turn is just another way to express the feed per revolution. This distance determines how much material is removed per pass and influences the finish; for example, 0.005 inches per turn means the tool advances that amount every time the work makes a full rotation. If you turn faster or choose a larger travel per turn, more material is removed per revolution and the part progresses faster along its length.
