Advanced integrated machine control for fast tool assisted ultra precision machining

The mechanical integration of additional highly dynamic axes such as Fast Tools into ultra precision lathes can be regarded as state of the art to achieve the objectives of advanced optical components. In contrast to that, neither advanced control strategies for ultra precision machines nor the control integration of additional Fast Tool systems have been sufficiently developed yet. Considering a complex machine setup as a mechatronic system, it becomes obvious that enhancements to further increase the achievable accuracy and at the same time decrease cycle times and error sensitivity can only be accomplished by advanced, integrated control systems. Additionally, the major drawback of a discontinuous safety concept has to be inhibited to enable efficient and safe machining. At the Fraunhofer IPT a novel, fully integrated control approach has been developed to overcome the drawbacks of state- of-the-art machine controls for ultra precision processes
