Abstract
A method and apparatus for quickly changing CNC machine tools is presented. Tool changes of 40 seconds or less are possible. A tool repository of linearly spaced apart tool forks translates to a storage position for CNC machining operations. For tool changing, the tool repository translates to a staging location, where an existing tool may be deposited to an empty location in the tool repository, whereupon another tool may be selected and engaged on the CNC machining spindle. The tool repository retracts to a storage position, and CNC machining operations may continue. This design may be used for CNC machines with many additional axes of operation, and appears more compact, less expensive, more robust, and lighter that traditional turret carousel designs. Stacked tools 5 inches high and diameters of 8 inches may be used in one embodiment. In the same space 15 smaller tools of 1.5 inch diameter may be stored.
