Tooling assemblies for lathe machines, CNC threading lathes, and methods of milling threads in tubular workpieces

A computer numerical control (CNC) threading lathe, comprising:

• a base with a plurality of z-rails;
• a work beam slideably disposed along the z-rails and having a plurality of x-rails;
• a tooling assembly having a tool platform slideably disposed along the x-rails and movable between a turning position and a thread milling position, a milling tool holder workable to releasably secure a single thread milling tool at a time therein and fixedly secured to the tool platform, a milling tool drive operatively connected to the milling tool holder and operable to rotate the milling tool holder relative to a work holder, and a rotationally-fixed static tool holder workable to releasably secure a single static tool at a time therein and fixedly secured to the tool platform at a location offset by a fixed distance from the milling tool holder;
• and
• a controller operably connected to the work beam and the tool platform, the controller including a processor coupled to a non-transitory machine readable memory, the non-transitory machine readable memory having program modules recorded thereon, at least one of the program modules, when read by the processor, causes the processor to execute operations that cause the tool platform to move between the turning position and the thread milling position, and to operate the work beam and the tool platform to remove material from a workpiece in a turning operation that uses the static tool, and mill threads on the workpiece in a thread milling operation that uses the thread milling tool, wherein the thread milling operation is performed while the workpiece is being rotated.
