A control device controls a table lifting mechanism such that a sheet metal is bent to have a temporary bending angle that is wider than a target bending angle and calculates a first bending angle of the sheet metal bent to have the temporary bending angle. The control device removes a load applied to the sheet metal, calculates a second bending angle of the sheet metal, and calculates a spring back amount. The control device calculates a lowering amount for bending the sheet metal in consideration of the spring back amount and controls the table lifting mechanism to lower an upper table. The control device, after the sheet metal is bent to have the target bending angle, removes the load applied to the sheet metal, and calculates a final bending angle of the sheet metal.

A device determination system includes an assistance device configured to assist a work for a workpiece stacked in a stacking area and having portability so as to be freely arranged, an image capturing device capable of capturing an image of the stacking area, and a control device configured to determine an arrangement position and an arrangement orientation of the assistance device in the stacking area based on the captured image captured by the image capturing device, in which the assistance device includes an indicator by which a position and an orientation of the assistance device reflected in the captured image can be identified, and the control device detects the indicator included in the captured image so as to determine the arrangement position and the arrangement orientation.

A control device performs control to bend a first sheet metal and a second sheet metal. The control device determines whether a difference between, a fourth bending angle obtained by temporarily bending the second sheet metal, and a first bending angle obtained by temporarily bending the first sheet metal, is within a predetermined angle. If the difference between the fourth bending angle and the first bending angle is within the predetermined angle, the control device does not calculate a spring back amount of the second sheet metal, but lowers an upper table by a second depth value at the time of a driving operation of the first sheet metal or by a corrected depth value obtained by correcting the second depth value according to the difference between the fourth bending angle and the first bending angle.

An inner nozzle tip portion includes an inner nozzle opening configured to emit a laser beam and eject a first assist gas. An outer nozzle includes a stepped part provided at an outer nozzle tip portion and recessed inward from the outer nozzle tip portion, and an outer nozzle opening open to the stepped part to be a concentric circle with an inner nozzle opening, the outer nozzle opening being configured to eject a second assist gas. The stepped part includes a flat portion extending from a peripheral edge of the outer nozzle opening in a direction orthogonal to a direction of an axis, and the inner nozzle tip portion is located between the outer nozzle opening and the outer nozzle tip portion in the direction of the axis.

A slider configured to move in a predetermined direction between a setup area and a pickup area is provided in a vicinity of a loading machine that supplies a workpiece W to a working machine. The slider is recessed to form a placing part for placing a pallet. Guide mechanisms for supporting the slider so as to be movable in the predetermined direction are respectively arranged on both sides in a lateral direction orthogonal to the predetermined direction in the placing part of the slider. A drive mechanism for moving the slider in the predetermined direction is arranged on at least one side in the lateral direction of the placing part.

The tool reversing device includes a tool mounting part on which a tool used for bending processing is mountable; a rotating mechanism configured to rotate the tool mounting part in a direction perpendicular to a mounting direction of the tool, in which the tool mounting part includes a mounting part body formed into a U-shaped cross section so as to constitute a pair of wall parts and a bottom part, the mounting part body being configured to allow insertion of a shank part of the tool, an locking groove provided on at least one inner wall surface of the pair of wall parts so as to be engageable with a protrusion extending in the perpendicular direction and protruding from a surface of the shank part, and a plurality of locking strips provided at prescribed positions in the locking groove and configured to engage with the protrusion from the perpendicular direction.

An abutment mechanism operation control method includes determining, when, from among at least three abutment mechanisms each including a base part and an abutment part, each configured to be movable along each of a first operation axis in a first direction and a second operation axis in a second direction, and each arranged in parallel in the second direction, first and second abutment mechanisms positioned at both sides and with the abutment part offset with respect to a reference axis of the base part along the first direction, and a third abutment mechanism positioned between the first and second abutment mechanisms, are operated, whether an operation of at least one of the first and second abutment mechanisms and an operation of the third abutment mechanism interfere with each other, and causing at least one of the first, second, and third abutment mechanisms to perform an operation to prevent the interference based on a determination result.

A digital projector according to one aspect includes: a light source that irradiates an object to be machined with light; a low-magnification camera mechanism that captures a projected image of the object to be machined, generated by the irradiation by the light source; a beam splitter provided on a light path of the projected image; a high-magnification camera mechanism that captures the projected image, split by the beam splitter, in a range narrower than the low-magnification camera mechanism and at a magnification higher than the low-magnification camera mechanism; and a display that displays a low-magnification image captured by the low-magnification camera mechanism and a high-magnification image captured by the high-magnification camera mechanism. The high-magnification camera mechanism includes a high-magnification image-forming lens that enlarges the projected image to a predetermined magnification, a high-magnification camera that captures the projected image enlarged, and a high-magnification camera movement mechanism that changes an imaging position of the high-magnification camera with respect to the projected image.

A lay-out data creation device includes a laying-out unit configured to lay out, based on product data including a shape of a product, a cutting path through which a processing machine for laser cutting cuts the product from a material. The laying-out unit: in a case where a notch is included in an outline of the product, sets a joint to the product or an offcut the joint being for connecting a hole area including the notch in an outline of the hole area; and lays out the cutting path to the outline of the hole area and the outline of the product excluding the notch so that a part of the outline of the hole area is left uncut depending on the joint.
