摘　　要：文中根据等距型面曲线的廓形方程研究了其廓形特征和检测信号数据特点,并应用小波分析对其检测信号进行处理,实现了对"噪声"的去除和误差的分离,能够较为精确地检测出等距型面形状的评价参数和轮廓度误差,对于评价等距型面的加工质量有一定的实际应用价值。The outlining characters of the isometric polygonal profile and the measuring signal are studied according to its equation, the noise and errors are separated from the measuring signal by using wavelet analyze to process the measuring signal, so it can get the precise the evaluation parameters and outlining errors, which has the practical values to judge the process quality of isometric polygonal profile.
