摘要： A projector (30) emits laser light (L30) in such a way that the laser light passes through between a punch (14) and a die (24). An optical receiver (41) includes a photodetector, and determines whether the optical receiver is in a light receiving state or a light obstructing state of the laser light (L30). When an upper table (10) is lowered, a safety controller (42) controls lowering of the upper table (10) to stop, when it is determined that the optical receiver (41) is in the light obstructing state in a period in which a condition is satisfied that a first distance between a tip of the punch (14) and an upper end of a material (W) is equal to or greater than a second distance between the tip of the punch (14) and the photodetector, and controls the lowering to continue without stopping the lowering of the upper table (10) even when it is determined that the optical receiver (41) is in the light obstructing state in a period in which a condition is satisfied that the first distance is less than the second distance.

摘要： A laser processing machine includes a beam parameter product variable device (31) configured to vary beam parameter products of a laser beam, and a beam diameter variable device (32) configured to change a beam diameter of the laser beam emitted by the beam parameter product variable device (31). The beam parameter product variable device (31) sets beam parameter products of a laser beam to a predetermined value. The beam diameter variable device (32) includes a first lens (28) that is movable in an optical axis direction and having a positive focal length, and converts divergent light of a laser beam emitted from an emission end of the laser beam into convergent light, and a second lens (30) that is movable in the optical axis direction and having a negative focal length on which the convergent light is incident. A third lens (27) having a positive focal length, focuses the laser beam emitted from the beam diameter variable device (32), and irradiates a plate material with the focused laser beam.

摘要： A horizontal band saw machine for cutting a workpiece by an endless band saw blade includes a vise mechanism provided on a downstream side of a cutting position and having a pair of jaws, a vertically-movable cutting head, a pair of saw blade wheels provided rotatably on the cutting head, the band saw blade looped over the pair of saw blade wheels, a saw blade guide mechanism having a pair of saw blade guides that are suspended from the cutting head, a contact guide attached to the other of the pair of jaws, a coupling bracket connected to the other of the pair of saw blade guides to locate a distal end thereof below the other of the pair of saw blade wheels, and a follower member provided at the distal end of the coupling bracket to contact with the contact guide slidably. The contact guide and the coupling bracket are configured to move one of the pair of saw blade guides until the follower member contacts with the contact guide when the band saw blade is fed circularly in a state where the band saw blade is clamped by the one of the pair of saw blade guides.

摘要： CAM (20) sets an evaluation region in an adjacent plane to a target plane; calculates the position of the extremity of the product profile in the axial direction within the evaluation region; sets a first line segment passing through the position of the extremity and extending orthogonally to the axis in the target plane; locates a processing area in the range surrounded by the first line segment, a second line segment, and the product profile, the second line segment extending in the axial direction from an end of the first line segment to the product profile; allocates a trajectory for laser beam cutting to form a notch or a hole in the processing area; and allocates a trajectory for laser beam cutting to cut the material along the product profile. This can normally perform even cut-off processing of the material.
