The paper presents a sensor based supervisory control system for cylindrical grinding processes which ensures reliable process monitoring and control in the presence of process disturbances. The system makes use of different processing techniques and process models to reliably detect incipient and abrupt symptoms of undesired process states and tool wear. As a result the supervisory system manages different actions to keep the process within the optimal working region. The system consists of two levels which act in parallel. The objective of the first optimisation level is to maximize the material removal rate, simultaneously satisfying restrictions on surface roughness, out-of-roundness and waviness errors and on grinding temperature. At the same time the second, geometrical control level is responsible for the removal of the initial shape error by stabilising the motion trajectory of the grinding wheel in relation to the part being ground. The concept of the supervision system was evaluated by a preliminary experiments to prove its effectiveness.
