A plasma computer numerically controlled (CNC) cutting machine is controlled by a computer such as a personal computer capable running an operating system and software programs. In an embodiment, the computer executes a CNC program to control movement of a plasma torch to cut parts from a workpiece while a spectrometer determines an emissions spectra of light emitted as the torch cuts the workpiece. The spectrometer cooperates with software running on a computer to analyze the metal as it is being cut by the CNC cutting machine and determine a composition. In embodiments, the composition is compared to an expected composition and saved in a database with identifying information; in a particular embodiment the database is queried to provide identifying information of metal having similar composition to the workpiece.

The invention relates to a method for predicting the tilt inclination of a workpiece part that is being cut free from a remaining workpiece using a machine tool during a machining process, and that rests on one or more supports, said method comprising the following steps: determining one or more possible tilt edges about which the workpiece part being cut free might tilt. For at least one potential tilt edge, particularly for each potential tilt edge, determining tilt moments that act on the workpiece part in different states of the machine tool, and on the basis of the determined tilt moments, determining whether the workpiece part would tilt about a tilt edge.

A fully automated plasma sheet metal cutter that can be integrated into a HVAC coil-line and which increases the precision of cutting, decreases the time it takes to cut a particular component sheet metal part, and offers flexibility in cutting different sized and shaped holes or openings. Further, since the system is fully automated, it eliminates the error or cost attributed to a portion of the cutting process that heretofore has been associated with a manual laborer.

A machine for the deposition of material for the production of pieces, with a structural housing including an inner chamber in which an arc torch operates in order to melt a strand of material with which pieces are formed on a supporting table; the arc torch is mounted on a frame positioned horizontally in the upper part of the chamber, on which the arc torch is mounted with a movement system driven by several actuation devices located on the outside of the structural housing. The supporting table is positioned below the frame in an assembly that can move towards or away from the frame, with a side sub-chamber located facing the supporting table and equipped with a cover that opens outwards, and towards which the supporting table can pivot for the removal of the pieces.

The invention refers to a machine for 3D processing of volumetric metal objects with random shapes and sizes, in particular for thermal and/or laser cutting of holes and random contours in metal cabinets in their assembled state. The machine consist frame /1/, on the horizontally oriented beams /5/ are fixed linear guide ways, on which are placed two vertical oriented carriages /6/, wherein at their upper end the carriages /6/ are connected with a cross beam /7/ oriented toward axis X and perpendicular to axis Y, and on the cross beam /7/ are mounted at least two linear guide ways to which a horizontally oriented carriage /8/ is connected, with the possibility of movement along the axis X, as to the carriage /8/ is mounted a ram /9/, which move in the carriage /8/ with the possibility of movement in the vertical direction along axis Z.

A robotic welding equipment station to detect deviation of a tool center point of a welding torch. The station is provided with pairs of light emitting and detecting devices to emit and detect two separate light beams. The pairs of light emitting devices and detectors are oriented at an angle and spaced apart from each other such that the two light beams are at an angle to one another and the weld wire electrode is able to simultaneously interrupt both light beams when there is no deviation in a tool center point. The spacing prevents the weld wire electrode from interrupting both light beams when an increasing deviation of the tool center point propagates along the length of the weld wire electrode. First and second output signals generated by the first and second light detectors are received by a means for detecting deviation of the tool center point.

A plasma cutting system for measuring or monitoring the voltage between a plasma torch and the material being cut to determine a voltage or voltage signature and comparing that measurement against predetermined values to indicate that an initial pierce of the material is complete, and based on the measurement, moving the torch or the material to a different location for additional cutting. The system further provides a Fix Drawing Tool, which will automatically detect and fix gaps or overlaps in a drawing that are very difficult to find visually. These gaps and overlaps become a problem when trying to make a proper toolpath because a CAM program requires a clean, closed shape. The system also provides a Dynamic Corner Looping system, which automatically adjusts with the feed-rate and accelerations of the toolpath and plasma machine, eliminates unwanted dross, sharpens corners and minimizes material loss. A pendant tethering system is also disclosed for managing control of a CNC machine remotely. Additional disclosed functionality includes a data collection system, a manual hand wheel with 3D simulation and a multiple fabrication head management system.

A laser beam machine includes: a processor to machine a workpiece as the processor moves; a saddle that holds the processor, and moves the processor in a Y direction by moving in the Y direction along a guide extending in the Y direction; a cross rail on which the saddle is placed, the cross rail moving the saddle and the processor in an X direction by moving in the X direction along a guide extending in the X direction; and a bed on which the cross rail is placed via the guide extending in the X direction. The bed includes bases and beams, one of longitudinal end portions of the base is joined to a side surface of the beam, one of longitudinal end portions of the beam is joined to a side surface of the base.

A laser processing apparatus includes a support portion, a laser processing head, a vertical movement mechanism, a horizontal movement mechanism, and a controller. The controller controls starting and stopping of emission of a laser light from the laser processing head based on rotation information in a state where a focusing point is positioned at a position along a circumferential edge of an effective region in a target, while rotating the support portion, to perform a circumferential edge process for forming a modified region along the circumferential edge of the effective region in the target.

A laser processing head includes a tubular main body, and a gas supply part disposed in the main body and allowing an assist gas supplied from outside to flow into an internal space of the main body. The gas supply part includes a first gas supply hole extending along a first axis on a plane orthogonal to an axis of a tube of the main body and opening at an inner circumferential surface of the main body, a second gas supply hole forming a predetermined angle relative to the first axis around the axis extending along a second axis on the plane orthogonal to the axis and opening at the inner circumferential surface, and a flow path forming ring facing the inner circumferential surface with a predetermined interval, and forming a cylindrical space extending along the axis between the flow path forming ring and the inner circumferential surface.
