However, that approach enables a user to achieve only the light version of HDT because it takes a high level of skill to program a machine with G code. Achieving full HDT requires development of new CAD/CAM software to overcome that obstacle and enhance market penetration, and Schleinkofer tentatively expects a developer to introduce the needed software Ceratizit in September at the EMO Hannover trade A demonstration of High Dynamic Turning with a FreeTurnshow in Germany.
