摘要： A device for compensating a torque produced on a movable axle in a machine tool or production machine by a gyrostatic effect includes a rotating useful machine system attached to the movable axle and producing a useful angular momentum, and a rotating machine counter-system attached to the axle and producing a counter angular momentum. The magnitude of the counter angular momentum is substantially identical to the magnitude of the useful angular momentum. The useful torque produced by a movement of the rotating useful machine system through a temporal change of the useful angular momentum is at least partially compensated by a counter-torque produced by a temporal change of the counter angular momentum. This arrangement represents a simple device for compensating a torque produced by the gyrostatic effect on a movable axle of machine tolls and production machines.

摘要： A system for guiding movement of a movable machine element of a machine, such as a machine tool, production machine and robot, receives user input data relating to a travel movement of machine element and an optimization criterion selected from a robust travel movement, where a smallest number of natural frequencies of the movable machine element is excited, and a time-optimized travel movement, where from the natural frequencies of the movable machine element only those natural frequencies are excited that do not include a main natural frequency. The system then determines from the movement profile coefficients of polynomial functions and a position setpoint variable based on the coefficients. The travel movement of the machine element is executed in response to the determined position setpoint variable.

摘要： The excitation of an oscillation in a mechanical system, such as a machine element, subjected to a jerk can be suppressed or at least attenuated by rounding a corresponding jerk curve and/or by tuning the stop band of a bandstop filter to the characteristic frequencies of the mechanical system or machine element. In combination, both measures can improve the positioning accuracy while at the same time minimizing excitation of oscillations.

摘要： Parallel kinematics with rod guidance are nowadays used in machine tools, production machines and robotics. Changes in rod length caused by the special position of the moving work platform (P), by its acceleration and other force impact, can lead to positional errors. Such errors are eliminated by means of piezo-actuators (PA1–PA6) which are integrated into the rods (S1 to S6).
