    Abstract: A method for computer numerically controlled processing may include receiving configurations for a fabrication in which a computer numerically controlled machine processes a material to achieve one or more designs. An analysis may be performed to determine whether a thermal event occurs during the fabrication. The analysis may include performing one or more of a time-variant simulation and a time-invariant simulation of the fabrication. The thermal event may include one or more regions of the material exhibiting an undesirable response to the electromagnetic energy delivered to the material. One or more outputs may be generated based on the result of the thermal verification. The outputs may include a visualization of the quantity of energy exposure across the material, an alert if a thermal event is determined to occur during the fabrication, and corrective actions for resolving potential thermal events.

    Abstract: Disclosed embodiments include laser cutting tools. Some laser cutting tool embodiments include (i) at least one laser source configured to generate at least one laser beam having sufficient power to cut material, (ii) one or more processors, and (iii) tangible, non-transitory computer-readable memory comprising program instructions executable by the one or more processors to cause the laser cutting tool to perform laser cutting tool functions. In some embodiments, the functions include causing a cutting path to be projected onto a surface of a material, and controlling the at least one laser source to apply the at least one laser beam onto the material sufficient to implement a cut along the cutting path projected onto the surface of the material.

    Abstract: A method may include projecting, onto a surface within a computer numerically controlled machine, a structured light having a known property. One or more sensors may generate an image of the structured light projected on the surface within the computer numerically controlled machine. One or more characteristics of the surface may be determined by comparing a property of the structured light shown in the image to the known property of the structured light. Examples of characteristics include a size, a distance to the surface, a height, a thickness, an angle of the surface, edges, surface properties, jigs, fiducial alignment markers, patterns encoding data, and visual designs on the surface of the material that are intended for reproductions. A surface map indicating the characteristics of the surface at various locations may be generated to enable, for example, a calibration, alignment, and/or optimization of the computer numerically controlled machine.

    Abstract: A method for computer numerically controlled processing may include generating a user interface to enable the configuration of an edge treatment. The user interface may also be generated to enable the configuration of a design corresponding to a combination of the first object and the second object generated by applying one of a plurality of Boolean operation. A computer numerically controlled machine may be configured to deliver an electromagnetic energy in order to effect, in a material, one or more changes corresponding to the edge treatment and/or the design configured by the user. For example, the one or more changes corresponding to the edge treatment may include a variable depth engraving along at least a portion of a perimeter of a material.

    Abstract: A method may include generating, by a camera having a view of an interior portion of a computer-numerically-controlled machine, an image comprising a pattern. The image can be transformed into a set of machine instructions for controlling the computer-numerically-controlled machine to effect a change in a material. The change can correspond to at least a portion of the pattern. At least one machine instruction from the set of machine instructions can be executed to control the computer-numerically-controlled machine to effect at least a portion of the change. The execution can include operating, in accordance with the at least one machine instruction, a tool coupled with the computer-numerically-controlled machine. The tool can be configured to effect the change on the material. Related systems and articles of manufacture, including computer program products, are also provided.

    Abstract: 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.
