A method for determining a dynamic response of a machine having at least one axis, including performing a measurement run for each axis of the machine over an entire work area of each respective axis, capturing and recording data associated with each measurement run, determining a time-frequency representation of recorded data using a data processing unit, and analyzing the time-frequency representation or a related representation using an image processing algorithm.

Method and system for determining the dynamic response of a machine

In a method for determining a deviation of a spatial orientation of a beam axis (S) of a beam processing machine from a spatial nominal orientation (S) of the beam axis (S), contour sections (KA, KB) are cut with a processing beam into a test workpiece from two sides of the workpiece. The contour sections (KA, KB) extend parallel to a nominal orientation of a rotation axis (B, C), where the rotation axis is to be calibrated. The contour sections (KA, KA) are probed from one side of the test workpiece by a measuring device for determining the spatial position of the contour sections (KA, KB). Deviation of the spatial orientation of the beam axis (S) of the beam processing machine from the spatial nominal orientation (S) is determined based on the spatial positions of the contour sections (KA, KB).

Axis calibration of beam processing machines

Methods, machines, and computer-readable mediums for determining distance correction values of a desired distance between a laser processing nozzle on a laser processing head and a workpiece during laser processing of the workpiece are provided. In some implementations, the workpiece is scanned along a desired path of a surface of the workpiece separately by the laser processing nozzle and a measurement head arranged in place of the laser processing nozzle on the laser processing head, with a capacitively measured distance identical to the desired distance. The measurement head has a lower lateral sensitivity of a capacitance measurement than the laser processing nozzle. Respective scanned movement paths of the laser processing nozzle and the measurement head are determined. The distance correction values for the desired distance of the laser processing nozzle are then determined from the scanned movement paths determined with the laser processing nozzle and the measurement head.
