The TNC 640 mill-turn control has added new cycles and features such as enhanced graphics, interpolation turning, and gear hobbing. Additionally, new manual probing cycles promise to make it easier for operators to setup workpieces. The latest graphics package includes a CAD viewer that opens any *.Step, *.Iges, and *.Dxf files, and allows an operator to evaluate the workpiece at the control. For machine builders, DCM (Dynamic Collision Monitoring) is available via a M3D converter. Through this PC tool, CAD files of components in the machining envelope can be merged, edited, and added to the Collision Monitoring. Other new features include Cycle 880 for gear hobbing of external cylindrical and helical teeth. This machining process is performed through synchronization of the tool and lathe spindles. Furthermore, the cycle positions the rotary axis to the required tilting position and performs the infeed movements to the workpiece in the radial direction, and the milling movements in the axial direction.
