摘　　要：平行度误差评定的关键在于基准拟合,其拟合精度决定误差评定结果之精度。对于平面基准和空间直线基准,数模重新整定,寻求全新算法,并论证其对"最小条件"要求的符合性,且通过了对程序进行的大量算例测试。在高精度基准拟合确定基础上,研发功能完全的平行度误差评定软件,经大量算例测试表明了其评定结果的高精度性。Baseline fitting is a key factor in parallelism error evaluation and the fitting accuracy can influence evaluation results. The paper used data mold to construct datum and space straight-line basis to find a new algorithm, proved the requirements of the ＂minimum conditions＂, and was tested by a large number of the algorithm. Based on the high-precision baseline fitting, the software of parallelism error evaluation was designed and the high-precision of evaluation result was assured by the testing.
