In a quick measurement module provided by the present invention, a first distance sensing unit and a second distance sensing unit are provided individually on a movable seat, so that when the movable seat is displaced along a linear shifting axis, the first distance sensing unit senses the distance from the first reference plane, and meanwhile, the second distance sensing unit senses the distance from the second reference plane, so as to sense the linearity accuracy in movement of the movable seat with respect to the first reference plane and the second reference plane. The first reference plane and the second reference plane are spaced apart by an angle other than a right angle, so that the linearity accuracy in movement in the two different planes, such as the horizontal linearity accuracy and vertical linearity accuracy, of the movable seat can be obtained through sensing.

A method for optimizing the execution of automated drilling systems controlled by a numerical control, NC, machine, wherein the NC machine performs the following steps: (i) identifying each drill executed by an automated drilling tool at first drilling event (t); storing a theoretical position of each executed drill at the event (t); (iii) calculating a learned position using a machine learning model and based on the stored theoretical position at the event (t); (iv) estimating an intermediate position by applying a tendency statistical function, and (v), if the difference between the intermediate position and the learned position is less than a pre-configured threshold, using the intermediate position for the drilling tool to position a next drill and execute it at a subsequent event (t+1).

An error measurement method for a machine tool measures an error in a machine tool that includes two or more translational axes, a table, and a spindle head. The error measurement method includes installing a masterwork having a plurality of targets on the table and detecting a position of each of the targets using a sensor mounted to the spindle head to acquire a measured value regarding the position of each of the targets and to acquire an error value regarding the position of each of the targets using each of the acquired measured values and a preliminarily acquired calibration value regarding the position of each of the targets. The error measurement method further includes calculating at least one disturbance index value indicative of a degree of disturbance in the measurement for each of the targets, and determining whether the disturbance index value exceeds a preliminarily set threshold.
