A lathe part is metal part made by a machine tool that rotates a workpiece such as cutting, sanding, knurling, drilling, deformation, facing, and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis. CNC stands for computer numerical control, is operated with precise design instructions to machine parts to precise specifications. The material part is held in place and rotated by the spindle as the cutting tool that works on the material is mounted and moved on various axes.
