Abstract
The invention relates to the technical field of optical processing, in particular to a method for determining optical processing technological parameters through component manufacturing tolerance distribution, which comprises the following steps of: representing component surface processing errors generated under technological parameters into a characteristic spectrum form, and combining error characteristic spectrums of different technological parameters into a set; and performing tolerance analysis on the error characteristic spectrum and the standard surface of the element in optical design software to obtain a characteristic spectrum needing to be strictly controlled, and comparing the strictly controlled characteristic spectrum with a characteristic spectrum set to obtain the process parameter corresponding to the optimal error characteristic spectrum, namely the optimal process parameter. According to the method, the technical problem that a machining method meeting the tolerance cannot be determined in an existing method is effectively solved, and a theoretical basis is provided for subsequent machining.
