Embodiment Construction
[0034] In order to make the purpose of the present invention, technical solutions and advantages described more clearly, the sample block (60mm * 60mm) surface of an actual milling is taken as an example below, in conjunction with the accompanying drawings in the embodiments of the present invention, to the technical solution in the present invention Give a full description.
[0035] Using a flatness measuring instrument to test the milled sample block to obtain the surface three-dimensional topography data A of the milled sample block k×3 . The instrument uses a non-optical measurement system with a resolution of 5nm and a measurement size range of 20-200mm. Measured point cloud matrix A k×3 Such as figure 1 As shown, the point with the z-coordinate of 1000 represents the missing data point.
[0036] The measured point cloud matrix A k×3 The x, y, and z coordinates in are extracted to obtain the corresponding component matrix X m×n , Y m×n ,Z m×n ; Among them, the dat...
