During soft‐turning of rings, both, deviation of the wall thickness and the shape occur. Additionally, further changes of shape result from the subsequent heat treatment. To ensure desired geometric tolerances, a high stock allowance for finishing is necessary. Geometric deviations of machined rings originate mainly from workpiece clamping during the machining process due to elastic deformation. Therefore, several special clamping devices are applied in industry to reduce workpiece deformation. But the choice of chucks is always a trade‐off between high flexibility and low part distortion. To ensure minimal part distortion in spite of using flexible clamping devices, clamping strategies and novel dynamical turning processes have been developed. Dynamical adapting of the depth of cut based on the measurement of geometric errors, is realized by using a tool actuator combined with an in‐process ultrasonic measurement system. This paper discusses the compensation potential of developed methods to reduce part distortion.
