A moving mechanism relatively moves a machining head emitting a laser beam, with respect to a sheet metal along a surface of the sheet metal. A beam vibrating mechanism vibrates the laser beam for irradiation on the sheet metal in a predetermined vibration pattern, while the machining head is relatively moved by the moving mechanism. A vibration control section controls the beam vibrating mechanism to progressively reduce an amplitude of the vibration pattern from a first position to a corner portion when the machining head moves toward the corner portion and reaches the first position before the corner portion by a predetermined distance, and progressively increase the amplitude of the vibration pattern until the machining head reaches a second position ahead of the corner portion by the predetermined distance from the corner portion, at a time of producing a product having the corner portion.

A laser assisted micromachining system, includes a working sliding, a tool module, a laser module, and a temperature control module for the processing of a workpiece. The laser module is disposed in the working slide and moves with the working slide in three-dimensional space. The temperature control module includes a temperature sensor, a cooler, a controller and a coolant, which detects the real-time temperature value of the cooler. The cooler is located in the working slide and supports the tool module. The controller controls the working state of the cooler according to the temperature feedback. Control signal induced by the temperature indicator, and the working state of the cooler are controlled by the controller. The coolant is used to control the temperature distribution of the cooler in the setting range. At the same time, the invention also provides a temperature control method for the laser assisted micro machining system.

The last arm which is closest to the workpiece has a tip or wrist which is configured to receive an end-of-arm tooling (EOAT) rotatable about the 6.sup.th axis of the robot. A mount for supporting a laser head assembly is coupled to the wrist so that the laser head assembly is not rotatable about the 6.sup.th axis of the robot.

A method for designing an additively-manufactured object includes: a slicing step of slicing a shape of the additively-manufactured object into weld bead layers each having a height corresponding to one bead layer using data of the shape of the additively-manufactured object, thereby generating a plurality of virtual bead layers; a reference direction setting step of setting, as a reference direction, a direction in which the sliced layer of the additively-manufactured object is continuously provided and extended in an intermediate layer disposed at a deposition-direction center of the plurality of virtual bead layers; and a bead adjusting step of adjusting a bead size of the weld bead to be formed in the plurality of virtual bead layers depending on a bead shape in a section perpendicular to the reference direction.

The controller executes first control for causing the laser light to be modulated such that the laser light is branched into a plurality of rays of processing light and a plurality of converging points of the plurality of rays are positioned in different positions in a direction perpendicular to an irradiation direction of the laser light. In the first control, the laser light is modulated such that, in the irradiation direction, the converging point of each of the plurality of rays is positioned on a side opposite to a converging point of non-modulated light of the laser light with respect to an ideal converging point of the processing light, or the converging point of each of the plurality of rays is positioned on a side opposite to the ideal converging point with respect to the converging point of the non-modulated light.

A laser machining tool that performs laser machining on a plate-shaped workpiece includes a table including protrusions and supporting the workpiece on upper ends of the protrusions, a laser head to perform boring machining by irradiating a laser beam along an outline of a hole to be formed in the workpiece on the table, a transporter to transport the workpiece that has undergone laser machining, and a rod-shaped tool to force out slag remaining in the hole. The workpiece is transported by the transporter until the hole is at a processing position including a discharge space for the slag, outside and below the table as seen in a plan view, and the slag remaining in the hole is forced out by the rod-shaped tool, at the processing position.

A laser machining tool is disclosed. The laser machining tool includes a machining device that has a movable carriage. A machining unit, which includes a machining head, is arranged on the movable carriage. The machining head is configured to direct a laser beam of laser light onto a workpiece to be machined.
