This article summarizes experimental analyses for the determination of process parameters that can be achieved in an industrial machine tool with parallel kinematics. Focus is on the examination of the machining results' dependency on position and direction. Therefore milling experiments are conducted, testing different positions and directions within the workspace. Surface quality, process forces, acceleration as well as vibration characteristics of the working platform are assessed. Based on measured frequency responses the stability limits are determined at different locations within the workspace. By these examinations it can be confirmed that the dependency of static and dynamic machine properties on position and direction has an influence on machining results. Best results are achieved in central positions of the machine used for most of respective operations. Furthermore it's represented that the machining results are comparable to conventional serial machines though parallel kinematics show a stronger dependency on direction.
