Resumen
The sevocontrol level in machine tools manages the axes based on requirements of velocity, position, and acceleration. The success of modeling and control techniques applied to this level settle the basis for production of parts with high quality as well as cycle time reduction. First, an introduction is presented for the three mayor control levels: adaptive control, interpolation, and servocontrol level. The drives and transmission components for traditional machine tools as well as for precision machines are discussed; including comparison between systems, such as linear versus rotational electric actuators. Later, relevant control techniques, such as Zero Phase Error Tracking Control (ZPETC) and Cross Coupling Control (CCC), are presented with experimental results. After that, modern control strategies to mitigate the effect of nonlinearities, model uncertainties, and perturbations are studied. Furthermore, the problem of High Speed Machining (HSM) is also reviewed. In addition, precision control for precision machining is examined. Finally, the future tendency of Open Architecture Systems (OAS) that allows the implementation of any control strategy in machine tools is presented. At the end, it is included a summary on: electric and mechanical components, control strategies, precision machining, high speed machining, and a discussion on why new control techniques are not available in commercially machine tools.
