The movement of a machine element of a machine that can be driven via a shaft with the aid of a motor can be guided by specifying a setpoint guidance variable describing a desired movement process of the machine element for the actuation of the motor and determining an actual pilot variable and/or an actual guidance variable from the setpoint guidance variable by subjecting the setpoint guidance variable to a digital path model which simulates the dynamic behavior of the machine element and the motor. The digital path model is parameterized by the total moment of inertia and the poles and zeros of the transfer function of the mechanical system consisting of motor, shaft and machine element.

Method and device for guiding the movement of a movable machine element of a machine

A control device for a machine, with at least one axis, is configured to accept first parameters and to render a first general technological problem as a first specific technological problem. The control device is configured to determine once in advance, for a sequence of values of a position or a temporal derivation of the position of the axis of the machine, a number of variables assigned to the respective value, to solve the first specific technological problem in an optimum way. The control device is configured to store the assigned variables in a memory and, after the storage of the assigned variables, is configured to accept a first execution command. Based upon the first execution command, it is configured to output the sequence of values to the axis and during output, is configured to activate the machine in accordance with the number of variables assigned to the respective value.

Control device with integrated optimizer

The invention relates to a method () for determining an optimised trajectory for a non-productive movement of a tool () of a machine tool, from a starting position () to an end position (). The non-productive movement is carried out in a spatially restricted travelling area () which is represented by geometric conditions. The method according to the invention is executed with the avoidance of collisions and comprises the step of determining a first trajectory () of the tool () by means of a travel-finding algorithm. In this step, the first trajectory () is optimised for the non-productive movement with respect to at least one selectable target parameter.

Trajectory determination method for non-productive movements

A method of controlling a non-productive movement of a tool from a starting position to an end position in a travel envelope of a machine tool includes the steps of a) providing a collision-free first trajectory for the non-productive movement of the tool, b) determining a second trajectory that is improved over the first trajectory with regard to a selectable target parameter using an algorithm, and c) checking the second trajectory for collisions and, if the second trajectory is free of collisions, providing an instruction corresponding to the second trajectory. The first trajectory in step a) includes plural rectilinear segments and the second trajectory in step b) includes a polynomial segment and, if the second trajectory is not free of collisions in step c), steps b) to c) are repeated so that the algorithm is provided with a modified model of the travel envelope in a repeat of step b).

A method for operating a technical system, an apparatus and method for determining a movement profile, control apparatus and the actual technical system that includes at least one drive to move at least one axis, wherein at least one optimized movement profile of the axis is calculated with the aid of an optimization method that calculates an optimized movement profile with reference to preset points of a movement profile and/or preset regions of the movement profile, where for simplified and particularly understandable use, the optimization method includes physical boundary conditions from the start of the optimization method, where the use and initialization of the technical system by the user is made more understandable, for example, and where the optimized movement profile is used to control the at least one drive of the technical system.
