Lathe Operations
Home > Toolmark Identification > Tool Manufacture > Cutting Operations > Lathe Operations
Lathe operations are those in which the exterior of a workpiece rotates against a cutting tool controlled by an operator or by automation.
The main categories of lathe operations are
- turning - rotates the exterior of a workpiece against a single-point cutting tool,
- facing - the cutting tool is used on the surfaces perpendicular to the rotating spindle,
- boring - a single-point cutting tool enlarges a hole beyond the capability of a drill or reamer and works the interior of a piece.
