In some aspects, material processing head can include a body; an antenna disposed within the body; a first tag, associated with a first consumable component, disposed within a flux communication zone of the body at a first distance from the antenna, the first tag having a first resonant frequency; and a second tag, associated with a second consumable component, disposed within the flux communication zone of the body at a second distance from the antenna, the second tag having a second resonant frequency that is different than the first resonant frequency, where the first and second resonant frequencies are tuned based upon at least one of: i) a difference between the first distance and the second distance; or ii) a characteristic (e.g., shape) of the flux communication zone in which the first tag and/or the second tag is disposed.

A moveable head of a computer numerically controlled machine may deliver electromagnetic energy sufficient to cause a first change in a material at least partially contained within an interior space of the CNC machine. A feature of the material may be imaged using at least one camera present inside the interior space to update a position of the material, and the moveable head may be aligned to deliver electromagnetic energy sufficient to cause a second change in the material such that the second change is positioned on the material consistent with the first change and with an intended final appearance of the material. Methods, systems, and article of manufacture are described.

Various embodiments may be generally directed to a welding system that monitors an output of the welding system to determine if an output arc should be extinguished or maintained. The welding system can compare an arc voltage output to a voltage threshold and a temporal threshold. When the arc voltage output exceeds the voltage threshold in an uninterrupted manner for the duration of the temporal threshold, an output weld current can be stopped. In turn, the output arc can be broken or extinguished. After a predetermined amount of time, the power source can be re-engaged to prepare for re-ignition of another arc. By tracking the amount of time the arc voltage output exceeds the predetermined threshold, a probability of unwanted arc outs can be reduced or minimized while still providing quick and reliable arc breaking when desired.

A method for designing an additively-manufactured object includes: a slicing step of slicing a shape of the additively-manufactured object into weld bead layers each having a height corresponding to one bead layer using data of the shape of the additively-manufactured object, thereby generating a plurality of virtual bead layers; a reference direction setting step of setting, as a reference direction, a direction in which the sliced layer of the additively-manufactured object is continuously provided and extended in an intermediate layer disposed at a deposition-direction center of the plurality of virtual bead layers; and a bead adjusting step of adjusting a bead size of the weld bead to be formed in the plurality of virtual bead layers depending on a bead shape in a section perpendicular to the reference direction.

A beam machining head (10; 100; 200) for beam cutting of a workpiece is provided, having an interface (12) for an energy beam source (14; 14, 201) for generating a focused machining energy beam (15; 206) selected from a particle beam source, a fuel fluid beam source, a plasma beam source and/or a source for electromagnetic radiation; an exit opening (16) for the machining energy beam bounded by an opening edge (18); an optical detector unit (19) for recording at least one image of an electromagnetic radiation (17) emitted from the workpiece (11) through the exit opening into the beam machining head (10; 100; 200) and induced in the workpiece by the machining energy beam; and a monitoring unit (30) connected in a data-transmitting manner to the optical detector unit for monitoring a positional relationship between a centre of the emitted electromagnetic radiation and the exit opening, wherein the monitoring unit (30) has: a first determination module for determining at least one position (180; 182) of the exit opening in the at least one image; a second determination module for determining at least one position (170) of the centre of the emitted electromagnetic radiation in the at least one image; and a third determination module for determining the positional relationship between the at least one position (170) of the centre of the emitted electromagnetic radiation and the at least one position (180; 182) of the exit opening (16). A beam machining device and a method for beam cutting are further disclosed.

A plasma torch moves to a piercing position. The plasma torch generates a plasma arc and starts a piercing step at the piercing position. Whether the piercing step is completed is determined based on the arc voltage. The plasma torch is held at the piercing position in the horizontal direction from the start of the piercing step until the completion of the piercing step. The plasma torch is moved in a predetermined direction including at least the horizontal direction after the piercing step is completed.

In a method for severing a solid body, a defined contour is stored in a control unit configured to detect contour breaches and to avoid contour breaches. A high-energy beam is moved along a contour on a surface of the solid body, with the surface of the solid body facing the high-energy beam, to produce with the high-energy beam a cutting gap. The contour on the surface is compared with the defined contour stored in the control unit, and avoidance of the contour breach is automatically deactivated when the contour on the surface of the solid body matches the defined contour and a contour breach is detected. Otherwise, the contour is omitted. Advantageously, the high-energy beam travels along the contour with an averaged line movement.

A computer numerically controlled machine may include a movable head configured to deliver electromagnetic energy to a part of a working area in which the movable head may be commanded to cause delivery of the electromagnetic energy. The interior space may be defined by a housing and may include an openable barrier that attenuates transmission of light between the interior space and an exterior of the computer numerically controlled machine when the openable barrier is in a closed position. The computer numerically controlled machine may include an interlock that prevents emission of the electromagnetic energy when detecting that the openable barrier is not in the closed position. The commanding may result in the computer numerically controlled machine executing operations of a motion plan for causing movement of the movable head to deliver the electromagnetic energy to effect a change in a material at least partially contained within the interior space.

An execution plan segment of an execution plan can be received at a control unit of a computer numerically controlled machine from a general purpose computer. The execution plan segment can define operations for causing movement of a moveable head of the computer numerically controlled machine to deliver electromagnetic energy to effect a change in a material within an interior space of the computer numerically controlled machine. The execution plan segment can include a predefined safe pausing point from which the execution plan can be restarted while minimizing a difference in appearance of a finished work-product relative to if a pause and restart are not necessary. Operations of the computer numerically controlled machine can be commenced only after determining that the execution plan segment has been received up to and including the predefined safe pausing point by the computer numerically controlled machine.
