In the present invention , a movement mechanism moves, with respect to a sheet (W) along the surface of the sheet, a machining head which emits a laser beam. A beam oscillation mechanism oscillates, in a predetermined oscillation pattern, a laser beam with which the sheet (W) is irradiated, while moving the machining head by means of the movement mechanism. If fabricating a product with corners, an oscillation control unit sequentially reduces the amplitude of the oscillation pattern from a first position (P1) to the corner, once the machining head has moved towards the corner and has reached the first position (P1) a predetermined distance (L1) before the corner, and the machining head controls the beam oscillation mechanism in such a manner that the amplitude of the oscillation pattern is sequentially made larger from the corner until a second position (P2) a predetermined distance beyond the corner is reached.
In the present invention, movement mechanisms (22 and 23) move, with respect to a sheet along the surface of the sheet, a machining head which emits a laser beam. A beam oscillation mechanism oscillates a laser beam with which the sheet is irradiated, while the machining head is being moved in relative terms by the movement mechanisms (22 and 23). A machining condition setting unit (507) sets pattern selection information which selects the oscillation pattern for a laser beam generated by the beam oscillation mechanism to correspond to machining conditions including the machining speed of the sheet by relatively moving the machining head by means of the movement mechanisms (22 and 23) and which are specified for each machining command for machining the sheet in the machining program generated to machine the sheet, and parameters which determine the way in which the laser beam is oscillated by the oscillation pattern.
In the present invention, a movement mechanism (22, 23) causes a machining head (35) that emits a laser beam through an opening (36a) of a nozzle (36) to move relative to sheet-metal (W) along the surface of the sheet metal (W) in order to cut the sheet-metal (W) so as to manufacture a product having a prescribed shape. While the movement mechanism (22, 23) causes the machining head (35) to move relatively, a beam oscillation/displacement mechanism (32) oscillates or displaces the laser beam emitted onto the sheet-metal (W) in order to manufacture the product. A movement mechanism control unit (505) controls the movement mechanism (22, 23) so as to cause the machining head (35) to move relatively in a first control period. An oscillation/displacement control unit (504, 5040) controls the beam vibration/displacement mechanism (32) so as to oscillate or displace the laser beam in a second control period that is shorter than the first control period.
The laser processing machine includes a beam oscillation mechanism that oscillates a beam spot on a surface of a sheet metal. The control device controls the beam oscillation mechanism so as to oscillate the beam spot with an oscillation component in a direction orthogonal to a cutting direction of the sheet metal in a non-holding region, in which a holding portion of the conveyance apparatus for conveying a product is not held, when cutting the product from the sheet metal by irradiating the sheet metal with the laser beam. The non-holding region is at least a part of a periphery of a protrusion portion of the product, or at least a part of a periphery of a recess forming region in which a recess of the product is formed.

LASER PROCESSING MACHINE AND LASER PROCESSING METHOD
This laser processing machine is provided with a beam vibrating mechanism for vibrating a beam spot (Bs) on a surface of a sheet metal (W). The laser processing machine cuts from the sheet metal (W) a region to be cut (product 200) having a corner portion (C1), while spraying the sheet metal (W) with an assist gas. A control device controls the beam vibrating mechanism so as to cause the beam spot (Bs) to vibrate, by at least a first distance (distance L2) after the beam spot (Bs) has reached the corner portion (C1), in a vibration pattern including a vibration component in a direction perpendicular to a cutting proceeding direction.
The present invention provides a cutting machine including a cutting machine (1) which comprises a machine body (100) and an NC device (200). The NC device (200) has a tool diameter correction amount calculation unit (201), a processing path calculation unit (202), and a drive control unit (203). The processing path calculation unit (202) generates a tool diameter correction control signal (TS). The drive control unit (203) generates a drive control signal (CS). When tool path control information, which has been set so as to control a tool path (TP) when cutting a portion corresponding to a corner of a final processed product with respect to a workpiece (W), is included in a processing condition (CP), the tool diameter correction amount calculation unit (201) generates tool diameter correction information for correcting the tool diameter of the tool path (TP). The machine body (100) controls the tool path (TP) so that the tool path (TP) becomes the target tool diameter at a position (KP) corresponding to the corner of the final processed product in the workpiece (W).

In the present invention, an assessment unit (70) assesses, on the basis of the light reception state of a photodiode (564) positioned nearest an upper die (12), whether or not a shadow of the upper die (12) cast by a laser (B) projected on an optical receptor (52) side has expanded to the photodiode (564). A deactivation unit (72) deactivates the photodiode (564) positioned nearest the upper die (12) if it is determined that the shadow of the upper die (12) has expanded to said photodiode (564). A detection unit (74) detects the presence or absence of foreign matter between the upper die (12) and a lower die (14) on the basis of the light reception state of a plurality of active photodiodes (56) while an upper table (26) is descending.
The laser processing machine includes a beam oscillation mechanism that oscillates a beam spot on a surface of a sheet metal. The control device controls the beam oscillation mechanism so as to oscillate the beam spot with an oscillation component in a direction orthogonal to a cutting direction of the sheet metal in a non-holding region, in which a holding portion of the conveyance apparatus for conveying a product is not held, when cutting the product from the sheet metal by irradiating the sheet metal with the laser beam. The non-holding region is at least a part of a periphery of a protrusion portion of the product, or at least a part of a periphery of a recess forming region in which a recess of the product is formed.
A beam displacement mechanism causes the position of a laser beam, emitted via an opening (36a) of a nozzle (36), to be displaced in the opening (36a). An assist gas supply device (80) supplies an assist gas to a processing head (35) during processing of a metal sheet (W). A control device (NC device 50), when implementing a piercing process outside a product, controls the beam displacement mechanism so that the position of the laser beam in the opening (36a) is displaced from the center of the opening (36a) to a position in a direction away from the product. The control device, when cutting the outline of the product, controls the beam displacement mechanism so that the position of the laser beam in the opening (36a) is displaced from the center of the opening (36a) toward the front in a cutting proceeding direction.
A beam displacement mechanism (galvanoscanner unit 32) causes a laser beam emitted via an opening of a nozzle attached to the tip of a processing head to be displaced. A light sensor (93) generates a sensor output value corresponding to the intensity of an incident laser beam. A beam displacement control unit (504) controls the displacement of the laser beam by the beam displacement mechanism. A center calculation unit (503), when the displacement of the laser beam due to the beam displacement mechanism is controlled by the beam displacement control unit (504) and at least three points at the edge of the opening have been irradiated with the laser beam, detects the positions of the at least three points on the basis of the sensor output value generated by the light sensor (93), and, on the basis of the detected positions of the at least three points, calculates the central point of the opening. The beam displacement control unit (504) controls the beam displacement mechanism so that the laser beam emitted via the opening is positioned at the central point calculated by the center calculation unit (503).
A cut-processing machine (1) comprises a numerical controller device (200). The numerical controller device (200) comprises a tool diameter correction amount calculation unit (201), a processing track calculation unit (202), and a drive control unit (203). If processing conditions (CP) include cutting tool change information in which a tool track (TP) is changed during cut-processing and a centre control point (CL) is provided so as to be fixed with respect to a processing surface of a final processing product when the tool track (TP) is changed, then: the tool diameter correction amount calculation unit (201) identifies a plurality of tool tracks (TP) included in the cutting tool change information, and generates tool diameter correction information (TC) that includes the plurality of tool tracks (TP), a processing surface formation location (MPL), a control centre point (CL), and a tool diameter correction value (MVL). The processing track calculation unit (202) generates a tool diameter correction control signal (TS).
