Turning: Engine Lathe Tool Post
Since the tool is stationary on a lathe, there is great flexibility for mounting the tool to best advantage. The tool post and carriage of a lathe provide several ways of positioning and feeding the tool. Below is shown the work area of an engine lathe.

The cutting tool is fixtured on the tool post, which sits atop the carriage assembly. The carriage can move the tool post along the axis of part rotation, perpendicular to the axial direction, and on a diagonal.

 



 
The tool post is shown below. The tool post can pivot the tool about a vertical axis and the cutting tool can be moved in and out along its long axis. The cutting tool is held in by the vertical screws, the heads of which can be seen above the cutting tool groove.
