Hey there, Thank you for introducing me to a new subject as well. Lathe operators are the one, who basically operates machines, which are generally used to give shape to steel or titanium kind of metals. They initially study a blueprint of the specific design required and as such initially it was manually set by the operator to get a design, but now are done through the computers They are the skilled labour kind of job available as a course generally in the ITI category. These are courses that are job oriented, after one finishes his class 10th. Hope this was helpful. Wish you good luck
