With Dynamic Efficiency, HEIDENHAIN combines important functions of TNC contouring controls for heavy machining. They make the machine operator’s work easier, but also make the manufacturing process itself faster, more stable and more predictable—in short, more efficient. It combines effective control functions with intelligent machining strategies in order to increase the metal removal rate and reduce machining time.
The package comprises three options:
Technical Information "Dynamic Efficiency"
Adaptive feed control optimizes the feed rate, taking into consideration the spindle power and other process data. Particularly when cutting conditions change during machining, e.g. through fluctuation cutting depths, tool wear, or changing material hardness, AFC ensures the best possible feed rate.
When cutter teeth engage solid material it can generate disturbing chatter vibrations that leave ugly marks on the workpiece surface. Chatter increases heavy and irregular tool wear. In some situations the tool can even break. The ACC algorithm increases the stability limit of the spindle speed, and therefore increases machine performance.
The TNC cycle trochoidal milling accelerates roughing of slots with any kind of contour It superimposes a circular tool movement over a linear feed movement. The cycle requires an end mill and enables it to remove material over its entire cutting edge.
With trochoidal milling the tool engages the material on a circular path. Wherever there is no contact on the circular path, AFC moves the tool at a much higher feed rate. This bring enormous cost saving over the entire machining process.
