| Abstract: | The advantages and disadvantages of all kinds of methods approximation to no-round curve are analyzed in this paper.And an optimizing calculation to approach no-round curve with beeline is introduced.According to the geometrical relationship between approaching line and processing error, the calculating formula and the flow chart of calculating program of processing error are pointed out with this arithmetic, it can be realized that the number of line, with which to approach no-round curve is the least within the range of precision. |
