A few days ago, Aerospace 303 undertook the measurement project of the National Defense Science and Technology Industry Bureau's measurement project "CNC Machine Space Geometric Accuracy Calibration Technology".
Now, the test group experts have completed the evaluation of the technical indicators and technical performance of the subject, and compiled the project acceptance test report. Now, the project has prepared all the acceptance data and plans to report it to the National Defense Science and Technology Bureau for acceptance review.
The content of this subject is to measure the diagonal of CNC machine tool by Doppler laser interferometer. Using the principle of split-axis step method, through the research on the principle of space error compensation of CNC machine tools, self-editing space error compensation software and Interface communication software, through the establishment of the spatial error compensation model, separates 12 error components of the CNC machine tool, automatically generates a spatial error compensation table, and writes the spatial error compensation table to the CNC machine tool through the interface communication software, realizing the space geometry of the CNC machine tool. Accuracy compensation, and the compensation effect is obvious. Compared with the current pitch error compensation method common to CNC machine tools, this is a big leap in technology.
