A cutting machine is provided with a machine main body and an NC device. The NC device controls the machine main body and has a tool radius compensation amount calculation unit, a machining path calculation unit, and a drive control unit. The tool radius compensation amount calculation unit generates tool radius compensation information. The machining path calculation unit generates a tool radius compensation control signal. The drive control unit generates a drive control signal. The machine main body has a machining unit and a tool path control unit. The machining unit cuts a workpiece by changing a relative position thereof with respect to the workpiece. Based on the drive control signal, the tool path control unit controls a tool path corresponding to a cutting tool and having a non-circular shape.

A method for manufacturing a display module includes preparing a display module comprising a plurality of layers and forming a through-hole in the display module. The forming the through-hole includes performing a first irradiation process of irradiating a first laser beam along a first boundary defining the through-hole, performing a second irradiation process of irradiating a second laser beam along a second boundary after the first irradiation process, and performing a third irradiation process of irradiating a third laser beam along a third boundary after the second irradiation process. A time interval between the first irradiation process and the second irradiation process may be different from a time interval between the second irradiation process and the third irradiation process.

A method of processing by controlling one or more beam characteristics of an optical beam may include: launching the optical beam into a first length of fiber having a first refractive-index profile (RIP); coupling the optical beam from the first length of fiber into a second length of fiber having a second RIP and one or more confinement regions; modifying the one or more beam characteristics of the optical beam in the first length of fiber, in the second length of fiber, or in the first and second lengths of fiber; confining the modified one or more beam characteristics of the optical beam within the one or more confinement regions of the second length of fiber; and/or generating an output beam, having the modified one or more beam characteristics of the optical beam, from the second length of fiber. The first RIP may differ from the second RIP.

The present disclosure discloses a laser cutting method, which relates to the technical field of laser cutting. The laser cutting method first removes the active material on the surface of a preset position of a to-be-cut part; and then performs the laser cutting on the to-be-cut part at the preset position to cut off the to-be-cut part.

A method for cleaving an optical fiber may include generating a laser beam, such as a CO.sub.2 laser beam, for a discrete time period. The laser beam may impact an optical fiber and form a discrete crater extending into the optical fiber from the outer surface thereof. The method may further include pausing generation of the laser beam for a discrete time period, and rotating the optical fiber about a longitudinal axis of the optical fiber. The method may further include repeating generation of the laser beam. A plurality of discrete craters disposed in an annular array about a circumference of the optical fiber may be formed. The method may further include separating the optical fiber into a main optical fiber portion and a cleaved portion after formation of the annular array of discrete craters.
