Visual preview for laser processing

The invention relates to a visual preview for laser processing. A computer numerical control machine may include a movable head configured to deliver electromagnetic energy to a portion of a work area in which the movable head may be commanded to cause delivery of 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 digitally controlled machine when the openable barrier is in a closed position. The computer digital control machine may include an interlock that prevents emission of electromagnetic energy when it is detected that the openable barrier is not in the closed position. The command may cause the computer digital control machine to perform an operation of a motion plan to cause a movable head to move to deliver electromagnetic energy to cause a change in a material at least partially contained in the interior space. 本申请涉及用于激光加工的视觉预览。一种计算机数字控制机器可以包括可移动头部
