Example Embodiment
[0017] An inscribed circle inspection method for comprehensive accuracy of numerical control machine tools according to the present invention. Firstly, a regular hexagon is processed on a bar, and then a nominal size is consistent with the size of the opposite side of the regular hexagon and is tangent to the regular hexagon. According to the symmetry and tangency of the inscribed circle and the regular hexagon, the overall accuracy of the machine tool is obtained, including the following steps:
[0018] A) Fix the test bar on the machine tool;
[0019] B) The tool uses the interpolation method to cut the bar to obtain a regular hexagonal body;
[0020] C) The same interpolation method is used for cutting in the regular hexagon to obtain an inscribed circle whose nominal size is consistent with the size of the opposite side of the regular hexagon and tangent to the regular hexagon;
[0021] D) According to the symmetry and tangency of the inscribed circle and the regular hexagon, ...
