摘要： A laser machine comprises: a head including optical parts allowing reflection of a laser beam or allowing the laser beam to pass through, while being rotatable about rotary axes, and a focusing optical system that focuses the laser beam; a moving mechanism that allows the head and a target to move relative to each other; and a control unit that controls rotations of the optical parts in such a manner that an irradiation intended position to be reached by an emission optical axis when the laser beam is emitted to the target moves in a curvilinear pattern or a linear pattern, controls movement by the moving mechanism so as to move the head and the target relative to each other, and controls emission output from the laser source so as to change a condition for emitting the laser beam based on the rotation angles of the optical parts.

摘要： A laser processing apparatus including a processing head and a light-focusing optical section for focusing a laser beam having a diffusion angle and enabling the laser beam having a convergent angle to be emitted from the processing head. The laser processing apparatus includes a transmissive optical member located upstream of the light-focusing optical section so as to transmit the laser beam while keeping the diffusion angle constant, or located downstream of the light-focusing optical section so as to transmit the laser beam while keeping the convergent angle constant. The transmissive optical member includes a focused-beam diameter increasing part for increasing a focused beam diameter of the laser beam transmitted through the focused-beam diameter increasing part, as compared to a focused beam diameter of the laser beam in a case where the laser beam is not transmitted through the focused-beam diameter increasing part but is focused by the light-focusing optical section.

摘要： A laser processing system including a laser processing unit, a controller controlling the processing unit according to a laser processing program, and a restart preparation apparatus performing a preparation process of the controller to resume the program execution after being suspended. The restart preparation apparatus includes an operating state judging section judging whether an operating state of the processing unit when suspending the program execution is in course of laser processing, and a restart condition specifying section specifying a restart condition of the processing unit when resuming the program execution, from among predetermined conditions, based on a judgment result. The operating state judging section judges that the operating state is in course of laser processing, if a predetermined operation command for processing the workpiece is output from the controller, or predetermined external information for processing the workpiece is input to the controller, at the instant of suspending the program execution.
