Abstract

A management system is for managing a material of a three-dimensional deposition device that shapes a laminate by irradiation with a light beam and supplying of the material. The management system includes a shape data acquisition unit that acquires shape data of the laminate; a shaping condition setting unit that sets, based on the shape data, a set shaping condition as a shaping condition for shaping the laminate by the three-dimensional deposition device; a shaping simulation execution unit that executes, based on the set shaping condition, a shaping simulation for shaping the laminate with the set shaping condition; and a required material amount acquisition unit that acquires, based on an execution result of the shaping simulation, a required material amount that is an amount of the material required for shaping the laminate by the three-dimensional deposition device.

First claim

The invention claimed is:

1. A management system for managing a material of a three- dimensional deposition device that shapes a laminate by irradiation with a light beam and supplying of the material, the management system comprising:
a shape data acquisition unit that acquires shape data of the laminate;
a shaping condition setting unit that sets, based on the shape data, a set shaping condition as a shaping condition for shaping the laminate by the three-dimensional deposition device;
a shaping simulation execution unit that executes, based on the set shaping condition, a shaping simulation for shaping the laminate with the set shaping condition;
a required material amount acquisition unit that acquires, based on an execution result of the shaping simulation, a required material amount that is an amount of the material required for shaping the laminate by the three-dimensional deposition device;
an output control unit that outputs information based on the required material amount to outside; and
wherein the required material amount acquisition unit includes, as the required material amount, an amount of the material ejected during a time from a timing at which ejection of the material is started to a timing at which shaping of the laminate is started, an amount of the material ejected from a deposition head after a timing at which supply of the material to the deposition head that ejects the material and irradiates the material with the light beam is stopped, and an amount of the material in a period in which the material is ejected without being irradiated with the light bean.

2. The management system according to claim 1 , wherein the laminate is shaped by solidifying the material that is being melted.

3. The management system according to claim 2 , wherein the shaping simulation execution unit executes, as the shaping simulation, a simulation for shaping the laminate by Directed Energy Deposition that ejects the material and irradiates the material with the light beam.

4. The management system according to claim 3 , wherein the shaping condition setting unit sets, as the set shaping condition, at least a supply speed of the material, power of the light beam, and a feeding speed of a deposition head that ejects the material and irradiates the material with the light beam with respect to a base part on which the laminate is shaped.

5. The management system according to claim 1 , wherein the shaping condition setting unit updates the set shaping condition based on quality data of the laminate acquired when the laminate is shaped by the three-dimensional deposition device with the set shaping condition.

6. The management system according to claim 1 , wherein
the shape data acquisition unit, the shaping condition setting unit, the shaping simulation execution unit, the required material amount acquisition unit, and the output control unit are provided to a manufacturing management system, and
the output control unit orders the material to a material management system that is different from the manufacturing management system based on the required material amount.

7. The management system according to claim 1 , further comprising:
a data acquisition unit that acquires, from a material management system that manages the material, material data indicating a property of the material used for shaping the laminate, and acquires quality data of the laminate shaped by the three-dimensional deposition device; and
a collation unit that collates the material data with the quality data, and determines whether the material used for shaping the laminate is appropriate.

8. A management method for managing a material of a three-dimensional deposition device that shapes a laminate by irradiation with a light beam and supplying of the material, the management method comprising:
acquiring shape data of the laminate;
setting, based on the shape data, a set shaping condition as a shaping condition for shaping the laminate by the three-dimensional deposition device;
executing, based on the shape data and the set shaping condition, a shaping simulation for shaping the laminate with the set shaping condition;
calculating, based on an execution result of the shaping simulation, a required material amount that is an amount of the material required for shaping the laminate by the three-dimensional deposition device;
outputting information based on the required material amount to outside; and
wherein the required material amount includes an amount of the material ejected during a time from a timing at which ejection of the material is started to a timing at which shaping of the laminate is started an amount of the material ejected from a deposition head after a timing at which supply of the material to the deposition head that ejects the material and irradiates the material with the light beam is stopped, and an amount of the material in a period in which the material is ejected without being irradiated with the light beam.
