Abstract: A method for synchronous control of a gantry mechanism with online inertia matching is applicable to a machine tool equipped with a gantry mechanism.

This method includes the steps of: obtaining gantry-mechanism information; detecting position information of the saddle on the crossbeam; evaluating the position information and the gantry-mechanism information to derive load-inertia variety information; and, evaluating the load-inertia variety information to adjust torque-output information of the drive motor corresponding to the respective driving apparatus.

Abstract: A method of determining an optimal operational parameter setting of a metrology system is described. Free-form substrate shape measurements are performed. A model is applied, transforming the measured warp to modeled warp scaling values. Substrates are clamped to a chuck, causing substrate deformation. Alignment marks of the substrates are measured using an alignment system with four alignment measurement colors. Scaling values thus obtained are corrected with the modeled warp scaling values to determine corrected scaling values. An optimal alignment measurement color is determined, based on the corrected scaling values. Optionally, scaling values are selected that were measured using the optimal alignment measurement color and a substrate grid is determined using the selected scaling values. A substrate may be exposed using the determined substrate grid to correct exposure of the substrate.

Abstract: A controller includes a determination circuit, a setting circuit, and a control circuit. The determination circuit is configured to determine whether a chatter vibration is occurring while a spindle is rotating and a workpiece is being cut.

The control circuit is configured to determine the change amount randomly from a range between the upper limit and the lower limit and configured to rotate the spindle at a second rotational speed obtained by changing a first rotational speed by the change amount that has been determined if the chatter vibration is determined as occurring while the control circuit controls the rotational speed of the spindle at the first rotational speed.

Abstract: Embodiments of the present disclosure include a data processing and control augmentation system capable of identifying overloading of one or more wind turbine assemblies and providing information to a wind farm controller to reduce a power output of each overloaded turbine. The augmentation system thus reduces the power output of each overloaded turbine and, in turn, reduces loads applied to the wind turbine assembly, such as for a period of time until conditions favorably change. A described analysis of the present disclosure is able to utilize several incoming data streams from sensors so arranged to measure wind effects on blades to calculate and compare cyclic loads to threshold limits to o keep the loads within design limits. The control strategy reduces premature failure of components within the wind turbine assembly, and can be applied across an entire wind farm, even with only a subset of wind turbine assemblies being retrofitted.
