A machine handling device for handling a sheet-metal workpiece includes a control device that comprises two sensing elements, and a testing station that includes a testing device configured to test functional capability of the control device. The testing device includes a respective electrically conductive testing-contact body for each of the two sensing elements of the control device. The testing station further includes a testing-evaluation device configured to apply a testing voltage between the respective sensing element and the corresponding testing-contact body. The testing-evaluation device includes a testing-measuring unit and a testing-comparing unit. The testing-measuring unit is configured to measure an actual value of a contact-dependent electrical variable that is dependent on a state of an electrically conducting contact between the sensing element and the testing-contact body. The testing-comparing unit is configured to compare the actual value of the contact-dependent electrical variable with a reference value of the contact-dependent electrical variable.

Methods and systems are implemented for piercing a metal workpiece by means of a laser beam and a process gas The methods and systems form a hole in the workpiece using the laser beam and using an inert gas as the process gas, such that the formed hole extends only partially through the workpiece, widen the upper part of the hole into a trough that surrounds the hole on the top side of the workpiece using the laser beam and using oxygen as the process gas, and fully pierce the hole using the laser beam and using oxygen as the process gas.
