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.

A gantry-type thermal cutting system includes a gantry; a thermal cutting device located on the gantry; a cutting table having a grated steel sheet; and a waste hopper removably connected to the gantry. The gantry is configured to move bi-directionally in a first direction. The thermal cutting device is configured to move bi-directionally in a second direction, the first direction being orthogonal to the second direction. The waste hopper is configured to move synchronously with the gantry in the first direction. The waste hopper is positioned under the gantry to capture waste from a thermal cutting process performed by the thermal cutting device.

A system includes a machine tool having a clamp. The system also includes a processing head configured to be temporarily held by the clamp of the machine tool. The processing head is also configured to deposit one or more media onto a workpiece. The processing head includes a guide configured to direct energy from an energy source onto the workpiece and/or the one or more media. The processing head also includes one or more supplies including one or more reservoirs within the processing head. The one or more reservoirs are configured to receive the one or more media, store the one or more media as the processing head is moved from one location to another location, and provide the one or more media.

A peel-off layer is finally formed in an area, i.e., a first inner area or a second inner area, in a workpiece that is closer to the center of the workpiece among a plurality of areas. The workpiece has a cylindrical shape, so that the second inner area is wider than the other areas, e.g., the second outer area, in which the peel-off layers are formed. Consequently, when the peel-off layer is finally formed in the second inner area, the internal stresses in the workpiece are dispersed in a wider range than when the peel-off layer is finally formed in the second outer area. Thus, large cracks thicknesswise of the workpiece are prevented from being developed from modified regions contained in the peel-off layer. Therefore, the amount of workpiece material to be disposed of in subsequent steps is reduced, resulting in increased manufacturing productivity.

A CNC machine includes a lower body; an upper body that extends from the lower body and is movably attached to the lower body; a tool that is movably attached to the upper body; and a flexible mat that is attached to the lower body. The tool may be a laser generator with the flexible mat resistant to the laser beam. The flexible mat has at least one orientation such that an outer periphery of the flexible mat is greater than the full extent of range of motion of the tool. The upper body may be connected to the lower body by a pivot mechanism configured to allow the upper body to pivot from a first position to a second position and to rotationally fix the upper body relative to the lower body in the second position, with the first and second positions being ninety degrees apart.

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.

Disclosed are methods of manufacturing a workpiece fixture (10) and also a target material fixture (10), for use in precision manufacturing processes. A sheet material is supported on a generic material fixture (10) and the sheet material precision processed to form support blades (16, 18) for a target workpiece fixture (10). Each support blade (16, 18) has a support locus and interstices are positioned in the support loci where a target pattern and the support loci coincide. Thus, there are no unnecessary clearances between the workpiece support (10) and the workpiece. The interstices that are present are located only where necessary to reduce or eliminate any interference between the precision manufacturing process and the fixture (10), when it is used in a precision process involving the target pattern.

In a laser cutting method, a cut slit of a welding protruding-tab configured to be bent by laser cutting along an outline of a processed part and press a peripheral surface of the processed part is laser-cut in advance in a periphery of the processed part that is cut from a workpiece, and an outline slit is formed by performing laser cutting along the outline of the processed part and a free end of the welding protruding-tab is welded to the peripheral surface of the processed part. According to the above described laser cutting method, it is possible to retain the processed part reliably and stably for a long period, and it is possible to easily separate the processed part from the workpiece with almost no trace left on the processed part.

Embodiments of the present disclosure generally relate to apparatus and methods for semiconductor processing, more particularly, to a thermal process chamber. In one or more embodiments, a process chamber comprises a first window, a second window, a substrate support disposed between the first window and the second window, and a motorized rotatable radiant spot heating source disposed over the first window and configured to provide radiant energy through the first window.
