Description

[Technical Field]

[0001] The present invention relates to a test method for testing a workpiece. [Background technology]

[0002] Various surface treatments have been put into practical use, including blasting processes such as shot blasting and microblasting, peening processes such as shot peening and laser peening, polishing processes such as barrel polishing and brush polishing, and burnishing processes such as roller burnishing. To achieve high-quality surface treatment, technology for testing the surface condition of a workpiece after processing is important. Examples of surface conditions that should be checked through testing include roughness, hardness, residual stress, and grain size. For example, Patent Document 1 discloses a surface property testing device that electrically tests the residual stress and other properties of a workpiece that has undergone surface treatment.

[0003] [Patent Document 1] Patent Publication No. 2016-224073 Summary of the Invention [Problem to be solved by the invention]

[0004] Testing the surface condition after processing requires a measuring device appropriate for the purpose of the surface processing. For example, a user who owns a processing device but does not own a measuring device will have to request such testing from the manufacturer of the processing device. However, such remote testing requires the effort, time, and cost of transporting the workpiece from the client's location to the tester who will perform the test. Possible solutions include transporting a portion of the workpiece from the client's location to the tester, or preparing a test piece made of the same material as the workpiece, but these methods result in the problem of being unable to perform testing that takes into account the shape of the workpiece. Similar problems can occur with various processes other than surface processing.

[0005] One aspect of the present invention has been made in consideration of the above-mentioned problems, and its purpose is to realize a testing method that enables remote testing that takes into account the shape of the workpiece without transporting the workpiece. [Means for solving the problem]

[0006] A testing method according to one aspect of the present invention includes the steps of acquiring shape data indicating the three-dimensional shape of a workpiece and material data indicating the material of the workpiece, creating a structure having the three-dimensional shape indicated by the shape data, selecting a test piece corresponding to the material indicated by the material data based on the material data, adding the test piece selected in the test piece selection step to the structure created in the structure creation step to create a pseudo workpiece, and testing the pseudo workpiece. [Effects of the Invention]

[0007] According to one aspect of the present invention, a test can be performed remotely, taking into consideration the shape of the workpiece, without transporting the workpiece. [Brief explanation of the drawings]

[0008] [Figure 1]1 is a block diagram showing a configuration of a test system according to an embodiment of the present invention; [Figure 2] FIG. 1 is a flow chart showing the flow of a testing method according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0009] (Test system configuration) The configuration of a test system S according to one embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a block diagram showing the configuration of the test system S.

[0010] As shown in Fig. 1, the test system S includes a 3D scanner 1, a computer 2, a computer 3, a 3D printer 4, and a test device 5. The 3D scanner 1 and the computer 2 are devices on the client side that requests a test, and the computer 3, the 3D printer 4, and the test device 5 are devices on the tester side that performs the test.

[0011] The 3D scanner 1 creates shape data that indicates the three-dimensional shape of the workpiece W. The 3D scanner 1 then provides the shape data D1 to the computer 2. The client inputs material data that indicates the material of the workpiece W into the computer 2 via a keyboard or the like. The computer 2 provides the shape data D1 acquired from the 3D scanner 1 and the material data D2 acquired from the client to the computer 3.

[0012] The computer 3 inputs the shape data D1 acquired from the computer 2 into the 3D printer 4. The 3D printer 34 then prints a structure Wa having a three-dimensional shape represented by the shape data D1 acquired from the computer 3, i.e., a structure Wa having a shape identical or substantially identical to the workpiece W. The material of the structure Wa is not particularly limited and may be metal or resin. The tester's computer 3 also provides the tester with the material data D2 acquired from the client's computer 2 via a display or other device. The tester selects a test piece P corresponding to the material indicated by the material data D2 acquired from the computer 3 from a pre-prepared test piece set. Here, the test piece P corresponding to the material indicated by the material data D2 refers to a test piece made of the same material as the material indicated by the material data D2, or a test piece in the test piece set made of a material whose properties are closest to those of the material indicated by the material data D2. The tester then creates a pseudo workpiece Wb by adding (embedding or pasting) the selected test piece P to the structure Wa created by the 3D printer 4. The test device 5 tests the pseudo workpiece Wb and provides the computer 3 with result data D3 representing the results of the test.

[0013] The computer 2 provides the result data D3 acquired from the test device 5 to the computer 2. The computer 2 provides the result indicated by the result data to the requester via a display or the like.

[0014] In this embodiment, the testing device 5 is composed of a processing machine 5a and a measuring device 5b. The processing machine 5a performs surface processing on the pseudo workpiece Wb. Examples of the processing machine 5a include a blasting device that performs blasting such as shot blasting or microblasting, a peening device that performs peening such as shot peening or laser peening, a polishing device that performs polishing such as barrel polishing or brush polishing, or a burnishing device that performs burnishing such as roller burnishing. The measuring device 5b measures the surface condition of the pseudo workpiece Wb that has been surface processed. Examples of the measuring device 5b include measuring devices that measure roughness, hardness, compressive residual stress, and some or all of the grain size.

[0015] As described above, the test system S includes a computer 3 that acquires shape data D1 indicating the three-dimensional shape of the workpiece W and material data D2 indicating the material of the workpiece, a 3D printer 4 that creates a structure Wa having the three-dimensional shape indicated by the shape data D1, and a test device 5 that tests a pseudo workpiece Wb created by adding a test piece P made of the material indicated by the material data D2 to the structure Wa.

[0016] Therefore, the tester can conduct a test using a pseudo workpiece Wb whose shape is the same as or approximately the same as the workpiece W and whose material is the same as or approximately the same as the workpiece W in some parts. Therefore, a test can be conducted remotely, taking into account the shape of the workpiece W, without transporting the workpiece W.

[0017] The test device 5 of the test system S also includes a processing machine 5a that processes the surface of the dummy workpiece Wb, and a measuring device 5b that measures the surface condition of the surface-processed dummy workpiece Wb.

[0018] Therefore, with regard to surface processing, tests can be performed remotely, taking into account the shape of the workpiece W, without transporting the workpiece W.

[0019] The test system S also includes a 3D scanner 1 that generates shape data D1, and a computer 3 that provides the shape data D1 and material data D2 to a computer 2 and obtains result data D3 from the computer 3 that indicates the results of the test.

[0020] This allows the client to easily request a remote test and easily know the results of the remote test.

[0021] (Test method flow) The flow of a test method M according to one embodiment of the present invention will be described with reference to Fig. 2. Fig. 2 is a flow chart showing the flow of the test method M.

The shape data generation process M1, the material data input process M2, and the result data output process M9 are processes performed by the client, while the structure modeling process M4, the test piece selection process M5, the pseudo workpiece creation process M6, and the test process M7 are processes performed by the tester.

[0023] The shape data generation process M1 is a process of generating shape data D1 that indicates the three-dimensional shape of the workpiece W. In this embodiment, the client uses a 3D scanner 1 to perform the shape data generation process M1.

[0024] The material data input step M2 is a step of inputting material data D2 indicating the material of the workpiece W into the computer 2. In this embodiment, the requester performs the material data input step using a keyboard or the like.

[0025] The shape and material data providing / acquiring step M3 is a step in which the computer 2 provides the shape data D1 generated in the shape data generating step M1 and the material data D2 input in the material data input step M2 to the computer 3, or the computer 3 acquires the shape data D1 from the computer 2. In this embodiment, the computer 2 and the computer 3 perform the shape and material data providing / acquiring step M3.

[0026] The structure modeling process M4 is a process of modeling a structure Wa having a shape indicated by the shape data acquired in the shape and material data providing / acquiring process M3. In this embodiment, the tester performs the structure modeling process M4 using a 3D printer 4.

[0027] The test piece selection step M5 is a step of selecting a test piece P made of the material indicated by the material data acquired in the shape and material data provision / acquisition step M3 from a pre-given test piece set. In this embodiment, the test piece selection step M5 is performed by a tester.

[0028] The dummy workpiece creating process M6 is a process of adding the test piece P selected in the test piece selecting process M5 to the structure Wa formed in the structure forming process M4. In this embodiment, the tester performs the dummy workpiece creating process M6.

[0029] The testing process M7 is a process for testing the dummy work Wb created in the dummy work creation process M6. In this embodiment, a tester uses the test device 5 to perform the testing process M7.

[0030] The result data providing / acquiring step M8 is a step in which the computer 3 provides the result data D3 indicating the test results to the computer 2, or the computer 2 acquires the result data D3 from the computer 3. In this embodiment, the computer 2 and the computer 3 perform the result data providing / acquiring step M8.

[0031] The result data output step M9 is a step of outputting the result data D3 acquired in the result data providing / acquiring step M8. In this embodiment, the computer 3 performs the result data output step M9 using a display or the like.

[0032] In this embodiment, the testing process 7 includes a processing process M7a and a measurement process M7b. The processing process M7a is a process of performing surface processing on the dummy workpiece Wb. Examples of surface processing include blasting processes such as shot blasting and microblasting, peening processes such as shot peening and laser peening, polishing processes such as barrel polishing and brush polishing, and burnishing processes such as roller burnishing. The measurement process M7b is a process of measuring the surface condition of the dummy workpiece Wb that has been subjected to surface processing. Examples of the surface condition to be measured include roughness, hardness, compressive residual stress, and some or all of the grain size.

[0033] As described above, the test method M includes a shape and material data providing / acquisition process M3 for acquiring shape data D1 indicating the three-dimensional shape of the workpiece W and material data D2 indicating the material of the workpiece W, a structure forming process M4 for forming a structure Wa having the three-dimensional shape indicated by the shape data D1, and a test process M7 for testing a pseudo workpiece Wb created by adding a test piece P made of the material indicated by the material data D2 to the structure Wa.

[0034] Therefore, the tester can conduct a test using a pseudo workpiece Wb whose shape is the same as or approximately the same as the workpiece W and whose material is the same as or approximately the same as the workpiece W in some parts. Therefore, a test can be conducted remotely, taking into account the shape of the workpiece W, without transporting the workpiece W.

[0035] Furthermore, the testing step M7 of the testing method M includes a processing step M7a for processing the surface of the dummy workpiece Wb, and a measuring step M7b for measuring the surface condition of the surface-processed dummy workpiece Wb.
