[0062] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0063] The present application provides a blanking planning method, device, equipment and product based on micro-damage sampling. By obtaining the correspondence relationship between the size parameters of the test block and the maximum sampling quantity of the micro-specimen, and substituting the required quantity into the above correspondence relationship to obtain the minimum size of the test block, micro-damage sampling blanking is carried out according to the minimum size of the test block, reducing material waste and improving the utilization rate of the test block.

[0064] To make the above objects, features and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0065] The blanking planning method based on micro-damage sampling provided by the embodiments of the present application can be applied to an application environment as Figure 1 shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be set up separately, integrated on the server 104, placed in the cloud or on other servers. The terminal 102 can send the shape of the test block, the size data of the micro-specimen and the required quantity of the micro-specimen to the server 104. After receiving the shape of the test block, the size data of the micro-specimen and the required quantity of the micro-specimen, the server 104 obtains the correspondence relationship between the size parameters of the test block and the maximum sampling quantity of the micro-specimen according to the shape of the test block and the size data of the micro-specimen; according to the required quantity and the correspondence relationship, obtains the minimum size of the test block; performs micro-damage sampling blanking according to the minimum size of the test block. The server 104 can feedback the obtained minimum size of the test block to the terminal 102. In addition, in some embodiments, the blanking planning method based on micro-damage sampling can also be implemented independently by the server 104 or the terminal 102. For example, the terminal 102 can directly obtain the minimum size of the test block according to the shape of the test block, the size data of the micro-specimen and the required quantity of the micro-specimen, or the server 104 can obtain the shape of the test block, the size data of the micro-specimen and the required quantity of the micro-specimen from the data storage system and calculate the minimum size of the test block.

[0066] Among them, the terminal 102 can be, but is not limited to, various desktop computers, laptop computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers, and can also be a cloud server.

[0067] In an exemplary embodiment, as Figure 2As shown, a blanking planning method based on micro-damage sampling is provided. This method is executed by a computer device, which can be specifically executed by a computer device such as a terminal or a server alone, or jointly executed by a terminal and a server. In the embodiments of the present application, taking the application of this method to Figure 1 server 104 in it as an example for illustration, it includes the following steps 201 to 204. Among them:

[0068] Step 201, obtain the shape of the test block, the size data of the micro-specimen, and the required quantity of the micro-specimen.

[0069] For different micro-damage sampling methods, due to their different process characteristics, the shapes of the obtained test blocks are different. In addition, for different performance test objectives and methods, the shapes and sizes of the required micro-specimens are also different. Therefore, when performing blanking planning, it is first necessary to determine the shape of the test block according to the micro-damage sampling method, and determine the size data of the micro-specimen and the required quantity of the micro-specimen according to the performance test objective and method.

[0070] The forms of micro-specimens are diverse. Since the small punch micro-specimen is the most widely studied and applied, in an exemplary embodiment, the small punch micro-specimen is selected as the form of the micro-specimen. In this embodiment, the small punch micro-specimen is a cylinder with a bottom radius of 5 mm and a thickness of 0.5 mm. Considering the requirements of wire cutting and surface pre-grinding, the thickness of the micro-specimen is set to 0.7 mm.

[0071] For the research of small punch specimens in this embodiment, based on different evaluation objects and different mechanical property test contents, the required quantities of the corresponding micro-specimens are also different. For example, 3 micro-specimens are required for tensile test at a single temperature, the required quantity of micro-specimens for fracture toughness test can be 3 or 7, 5 - 6 micro-specimens are required for creep conversion test, 27 - 36 micro-specimens are required for ductile-brittle transition test, and 30 - 50 micro-specimens are required for fatigue test. In practical applications, the required quantity of micro-specimens is determined according to the actual test requirements.

[0072] Step 202, obtain a corresponding relationship according to the shape of the test block and the size data of the micro-specimen; the corresponding relationship is the relationship between the size parameters of the test block and the maximum sampling quantity of the micro-specimen.

[0073] Step 203, obtain the minimum size of the test block according to the required quantity and the corresponding relationship.

[0074] Step 204, perform micro-damage sampling blanking according to the minimum size.

[0075] In another exemplary embodiment, the size data of the micro-specimen includes the thickness of the micro-specimen and the cross-sectional size of the micro-specimen; the size parameter is the thickness of the test block; the mechanical micro-damage sampling method is selected, and the shape of the obtained test block is a spherical crown. As Figure 3 shown, the above step 202 is replaced by the following steps 301 to 304:

[0076] Step 301, determine the maximum thickness of the test block according to the process characteristics of the micro-damage sampling method and the thickness of the micro-specimen.

[0077] Step 302, select multiple optional values of the test block thickness within the range of the maximum thickness.

[0078] Step 303, for any one of the optional values of the test block thickness, obtain the sampling number corresponding to the optional value of the test block thickness according to the cross-sectional size of the micro-specimen; the sampling number is the maximum sampling quantity of the micro-specimen.

[0079] Step 304, obtain the relationship between the test block thickness and the maximum sampling quantity of the micro-specimen according to each optional value of the test block thickness and the sampling number corresponding to each optional value of the test block thickness.

[0080] In another exemplary embodiment, step 303 specifically includes: dividing the optional value of the test block thickness to obtain multiple stratified thicknesses; each stratified thickness is less than twice the thickness of the micro-specimen. Calculate the cross-sectional radius of the spherical crown corresponding to each stratified thickness. According to the cross-sectional radius and the cross-sectional size of the micro-specimen, obtain the maximum sampling quantity corresponding to each stratified thickness. Sum the maximum sampling quantities corresponding to each stratified thickness to obtain the sampling number corresponding to the optional value of the test block thickness.

[0081] In another exemplary embodiment, the optional value of the test block thickness is an integer multiple of the thickness of the micro-specimen.

[0082] The principle of mechanical micro-damage sampling is as Figure 4 shown. The micro-specimen is excavated by coupling the high-speed rotation of the cutting shaft 401 and the rotary feed of the feed shaft 402. When the diameter of the cutter is 50 mm, the shape of the test block is a spherical crown. The cross-sectional schematic diagram of the spherical crown is as Figure 5 shown. Generally, the radius R0 of the spherical crown test block is less than or equal to 20 mm, and the thickness H is less than or equal to 5 mm. The relationship between the radius R0 and the thickness H is as follows:

[0083] (25 - H) 2 + R0 2 = 625.

[0084] Due to the thickness limitation of the spherical crown body, micro-specimen sampling can only be carried out layer by layer. In this embodiment, considering that the edge of the small punch cylinder micro-specimen has no influence on the mechanical property test, the optional values of the thickness of the spherical crown body specimen are evenly divided, and the thickness of each layer is equal to the thickness of the micro-specimen. Taking the maximum optional value of the thickness H of the spherical crown body specimen as an example, the method for dividing the optional values of the thickness of the spherical crown body specimen is as Figure 6 shown, where h0 represents the thickness of each layer after uniform division. In this embodiment, the value of h0 is equal to the thickness of the micro-specimen.

[0085] The sampling of small punches in each layer can be approximated as cutting as many small circles with a radius of r as possible within a large circle with a radius of R, as Figure 7 shown, where R represents the cross-sectional radius of each layer of the spherical crown body, and r represents the bottom radius of the small punch micro-specimen. Based on the principle that the small circles are tangent to the large circle and the small circles are tangent to each other, the maximum number of small circles arranged in the large circle within each layer can be achieved.

[0086] Taking the maximum optional value of the thickness H of the spherical crown body specimen as an example, after dividing the optional values of the thickness of the specimen, the cross-sectional radius of the spherical crown body corresponding to each sampling layer and the maximum number of micro-specimen samplings are shown in Table 1.

[0087] Table 1 Cross-sectional radius of spherical crown body corresponding to each sampling layer and maximum number of micro-specimen samplings

[0088]

[0089] Assuming that the thickness of the small punch micro-specimen is 0.7 mm and the maximum value of the thickness H of the spherical crown body specimen is 5 mm, within the maximum range of the thickness H of the spherical crown body specimen, multiple optional values of the specimen thickness are selected, and the different optional values of the specimen thickness and their corresponding maximum numbers of micro-specimen samplings are shown in Table 2.

[0090] Table 2 Maximum number of micro-specimen samplings corresponding to different optional values of specimen thickness

[0091]

[0092] According to Table 2, the relationship between the thickness of the spherical crown body specimen and the maximum number of micro-specimen samplings can be obtained. In this embodiment, a fitting relationship between the thickness of the spherical crown body specimen and the maximum number of micro-specimen samplings is established.

[0093] The fitting formula is as follows:

[0094] N = 1.1419H 2 - 1.4699H + 0.5641.

[0095] Where N is the maximum number of micro-specimen samplings; H is the thickness of the spherical crown body specimen.

[0096] According to the above fitting formula, a fitting curve between the thickness of the spherical crown specimen and the maximum sampling number of the micro-specimens is obtained, as Figure 8 shown.

[0097] In another exemplary embodiment, the size data of the micro-specimen includes the thickness of the micro-specimen and the cross-sectional size of the micro-specimen; the size parameter is the cross-sectional size of the specimen; the electro-discharge micro-erosion sampling method is selected, and the shape of the obtained specimen is a non-spherical crown. As Figure 9 shown, the above step 202 is replaced by the following steps 901 to 904:

[0098] Step 901, according to the process characteristics of the micro-erosion sampling method and the thickness of the micro-specimen, obtain the maximum thickness of the specimen.

[0099] Step 902, according to the shape of the specimen and the cross-sectional size of the micro-specimen, obtain multiple preferred values of the cross-sectional size.

[0100] Step 903, for any one of the preferred values of the cross-sectional size, according to the maximum thickness, obtain the sampling number corresponding to the preferred value of the cross-sectional size; the sampling number is the maximum sampling number of the micro-specimens.

[0101] Step 904, according to each preferred value of the cross-sectional size and the sampling number corresponding to each preferred value of the cross-sectional size, obtain the relationship between the cross-sectional size and the maximum sampling number of the micro-specimens.

[0102] In another exemplary embodiment, step 902 specifically includes: according to the shape of the specimen, obtain the cross-sectional shape of the specimen. According to the cross-sectional shape of the specimen and the cross-sectional size of the micro-specimen, by calculating the material utilization rate, obtain multiple preferred values of the cross-sectional size.

[0103] In another exemplary embodiment, step 903 specifically includes: divide the maximum thickness to obtain multiple layer thicknesses; each layer thickness is less than twice the thickness of the micro-specimen. According to the preferred value of the cross-sectional size and the cross-sectional size of the micro-specimen, obtain the maximum sampling number corresponding to each layer thickness. Sum the maximum sampling numbers corresponding to each layer thickness to obtain the sampling number corresponding to the preferred value of the cross-sectional size.

[0104] The principle of electro-discharge micro-erosion sampling is as Figure 10 shown. By discharging the electrode 1001, an electric arc 1002 is generated, and at the same time, it is cooled with the coolant 1003. The movement trajectory of the electrode 1001 is set, and the specimen 1005 is dug on the device 1004. According to the sampling principle, the front view and side view of the electro-discharge micro-erosion sampling specimen are respectively as Figure 11 andFigure 12 As shown. The lower base of the trapezoidal cross-section of the test block is L1, the upper base is L2, the width of the test block is W, and the thickness is H D . Generally, L1 is less than or equal to 50 mm, H D is less than or equal to 5 mm, and W is less than or equal to 20 mm.

[0105] The cross-sectional area of the test block obtained by micro-damage sampling with electric discharge machining is approximately rectangular. In this embodiment, according to the shape of the test block obtained by micro-damage sampling with electric discharge machining and the size data of the micro-specimen of the small punch, the strip layout method is selected for micro-specimen sampling. When the width W of the test block is limited to about 10 mm, single-row layout is carried out; when the width W of the test block is limited to about 20 mm, multi-row layout is carried out.

[0106] For any rectangular cross-section of the test block, by calculating the material utilization rate of the layout, when single-row layout is carried out, the optimal value of the length L of the rectangular cross-section d = 2mr, and the optimal value of the width W d = 2r; when double-row layout is carried out, the optimal value of the length L of the rectangular cross-section s = 2nr, and the optimal value of the width where r represents the bottom radius of the micro-specimen of the small punch, and m and n are any positive integers. In addition, by comparing the material sampling utilization rate, when the difference between the lower base L1 and the upper base L2 of the trapezoidal cross-section of the test block is 2r, the material utilization rate is the highest.

[0107] In this embodiment, according to the process characteristics of the micro-damage sampling method with electric discharge machining and the thickness of the micro-specimen of the small punch, the thickness H of the test block D is set to the maximum value of 5 mm. Taking the bottom surface of the test block as the reference, different optimal values of the length of the lower base L1 of the trapezoidal cross-section of the test block are set, and corresponding different optimal values of the length of the upper base L2 of the trapezoidal cross-section of the test block are obtained. Different optimal values of the width W of the test block are set. Since W is less than or equal to 20 mm under the micro-damage sampling process with electric discharge machining, the values of W are respectively set to 10 mm and 18.7 mm, corresponding to single-row layout and double-row layout respectively. According to the thickness H of the test block D and the thickness of the micro-specimen, the test block is equally divided into 7 layers in the thickness direction, and the thickness of each layer is 0.7 mm, that is, the thickness of the micro-specimen of the small punch. According to the optimal values of the cross-section size and the cross-sectional size of the micro-specimen, the maximum sampling quantity of each layer is obtained respectively. The maximum sampling quantities of each layer are summed up to obtain the maximum sampling number corresponding to the optimal values of the cross-section size.

[0108] When micro-specimen sampling is carried out by the single-row layout method, the different optimal values of the test block cross-section size and the corresponding maximum sampling quantity of the micro-specimen are shown in Table 3.

[0109] Table 3 Maximum sampling quantity of micro-specimen corresponding to different optimal values of test block cross-section size under single-row layout

[0110]

[0111]

[0112] According to Table 3, the relationship between the cross-sectional size of the specimen block in single-row layout and the maximum number of micro-specimens sampled can be obtained. In this embodiment, a fitting relationship between the cross-sectional size of the specimen block and the maximum number of micro-specimens sampled is established. The fitting formula is as follows:
