Abstract
Dual cutting milling tools for removing material from a workpiece include two cutting portions, with one cutting portion being configured for ruled milling, and the other cutting portion being configured for hemstitch milling. In this manner, the number of tool changes for a given manufacturing process may be reduced. Dual cutting milling tools include a first cutting portion and a second cutting portion both formed in a shank, with the first cutting portion being configured to perform hemstitch milling on the workpiece, and the second cutting portion being configured to perform ruled milling on the workpiece. Methods of removing material from a workpiece may include both hemstitch milling the workpiece with the first cutting portion of the dual cutting milling tool and performing ruled milling of the workpiece with the second cutting portion of the dual cutting milling tool, without changing tools in the milling machine.
