Lathe or CNC lathe is a machine usually used to produce turned parts, shaping different materials into desired shapes. In the CNC turning process, the lathe cutting tool is fed to the rotary workpiece that held in a chuck and removing excess materials from the block.A lathe machine can also perform lots of other operations, including facing, hard turning, parting, …

Constructive solid geometry is a technique of representing parts by adding and subtracting a set of primitive shapes. Automatic tool paths to machine a part with a rotating cutter are generated by taking the constructive solid geometric description of the part and replacing every primitive shape by an offset primitive, larger or smaller than the part by the cutter radius.

The term "machining center" describes almost any CNC milling and drilling machine that includes an automatic toolchanger and a table that clamps the workpiece in place. On a machining center, the tool rotates, but the work does not. The orientation of the spindle is the most fundamental defining characteristic of a CNC machining center.
