[Problem] To provide a configuration pertaining to: a three-dimensional shaped object for a lattice region having a uniform shape and firm bonding and an outer frame region disposed all around the lattice region; and a production method for the three-dimensional shaped object. [Solution] This method is for producing a three-dimensional shaped object on the basis of repetition of a step for forming a powder layer 3 and sintering the powder layer 3 using laser or electron beams, the method comprising: forming a sintered layer 41 in a lattice region 1 by scanning the lattice region 1 a plurality of times using the beam having a predetermined spot diameter in a one-side direction at predetermined intervals, and thereafter, forming a sintered layer 42 in the lattice region 1 by scanning the lattice region 1 in an other-side direction intersecting with the one-side direction in a similar manner; and forming a continuous sintered layer 43 in an outer frame region 2 by scanning the entire lattice region 1, which is surrounded by an inner line and an outer line, using the beam having the predetermined spot diameter. This three-dimensional shaped object is based on the method.

THREE-DIMENSIONAL SHAPING METHOD AND THREE-DIMENSIONAL SHAPING DEVICE
[Problem] To provide a configuration capable of performing efficient and uniform three-dimensional shaping using two-dimensional scanning, in which all laser beams that are scanned upon being transmitted through a plurality of galvanoscanners contribute to formation of a sintered surface. [Solution] The above problem is solved by a three-dimensional shaping method and device that utilize a plurality of galvanoscanners 3 that realize scanning of laser beams 7 along a two-dimensional direction of orthogonal coordinates or cylindrical coordinates by reflection from a first mirror 31, which vibrates via a rotation shaft 30 that is orthogonal to a transmission direction of the laser beams 7 transmitted through a dynamic focus lens 2, and from a second mirror 32, which vibrates via a horizontal rotation shaft 30 that is orthogonal to the rotation shaft 30 of the first mirror 31. The range of the vibration is made freely adjustable on the basis of control of the vibration, and then a region on a sintered surface 6 of a focus point or a nearby position thereof of the laser beams 7 that are irradiated from a direction inclined with respect to the surface of a table 4 is made freely selectable.

[Problem] To provide a configuration of a machine tool operation monitoring system for specifying, without the need of a particular distinction mark, a machine tool in which operation abnormalities have occurred. [Solution] This machine tool operation monitoring system is for detecting abnormal operations of machine tools 1, and solves the problem by, when a driving motor of at least one machine tool 1 is out of a range based on normal operation and/or when a constituent part of the machine tool 1 and movement conditions of a material are out of a normal range, specifying the at least one machine tool 1 in which operation abnormalities have occurred, through a. monitoring of a video image obtained by projection, to a camera 31, of reflected light from a reflection display plate 22 provided to the machine tool 1, or through b. monitoring of a difference in a direction of projecting, toward an optical sensor 32, of illuminating light of a lamp 21 provided to the machine tool 1.

The objective of the present invention is to provide a method for storing a tool which has been delivered from a machine tool, with which it is possible to reduce the amount of space required for operation of a tool conveying robot which stores the tool in a tool storage rack. The method for storing a tool is a method for storing a tool (4), delivered from a machine tool (1), in a tool storage rack (2) by means of a tool conveying robot (3), wherein, when storing the tool, the tool (4) being gripped by a robot arm (33) is pivoted in a vertical direction together with the robot arm (33) or is pivoted in a horizontal direction together with a support post (32) and the robot arm (33), either together with retraction of a platform (31) of the tool conveying robot (3) or after said retraction, until the tool faces in a front-back direction between the machine tool (1) and the tool storage rack (2) and a prescribed gap has formed between a rear end of the tool (4) and the tool storage rack (2).
Before modeling, the initial position of at least one interlock reference mark provided near a model is measured by first position measuring means, and the initial position of the interlock reference mark is measured by second position measuring means disposed to machining means. During modeling, the position of the interlock reference mark is measured by the first and second position measuring means. According to the initial position of the interlock reference mark before modeling and the positions of the interlock reference mark measured by the first and second position measuring means during modeling, the position to which a light beam is applied and the position of the machining by the machining means are corrected.
