It is the goal of the priority programme to control the surface states of metallic components during end machining operations with mechanical, thermal or chemical main effects, in order to guarantee an enhanced component life and reliability. The realization of dynamic process controls is pursued by the help of in-process soft sensors, which are characterized by a model-based process knowledge. The corresponding scientific questions can only be answered successfully by a joint cooperation of manufacturing, measurement and material technology. This will result in completely new specifications for the actuating variables of the machining processes. The manufacturing technology should in a first step develop a dynamical model of the machining process and the environmental conditions, particularly regarding the effects on the surface states. The task of the material technologies is the material state modelling with regard to the effects of the machining processes. The measurement technique however investigates sensors for the direct and indirect identification of surface states, as well for the identification of input factors which affect the machining process. In a second step the developed material and process models are to be combined with the sensors, which were developed by the measurement technology, in order to realize intelligent soft sensor structures. After the process integration of these soft sensors and the automated control of the machining process actuating variables, the conventionally fixed definition of process parameters can be replaced by a process control, based on the command variables component geometry and required surface state.
