Abstract
A method of machining a workpiece uses a complex tool having a number of inserts. The tool is installed on a tool holder of a machine tool and used for a turning machining operation on a workpiece, including rotating the workpiece, and selectively using one or more of the inserts on the complex tool, with the complex tool being fixed and held. A milling machining operation is performed on a workpiece using one or more of the inserts, with the complex tool being rotated and driven. Both turning machining and milling machining operations can be performed without changing tools. Extremely efficient machining is possible.
