[0038] The following describes the present invention in further detail with reference to the accompanying drawings and embodiments:
[0039] See figure 1 The invention provides a method for calculating the contact state of assembly mating surfaces with geometric errors, including the following steps:
[0040] Step 1. Place the coordinates of the measured points in the mating surface A and the mating surface B in the same three-dimensional rectangular coordinate system, and require the assembly path to be parallel to the Z axis (such as figure 2 As shown), and then calculate the closest distance d between the mating surface A and the mating surface B through the algorithm of solving the minimum translation distance. First through the coordinate conversion formula Place the mating surface A and the mating surface B in the same right-angled coordinate system according to the relative position in the actual assembly process, the assembly path is parallel to the Z axis, and it is requi...
