Spiral polishing path planning method based on evaluation function

The invention discloses a spiral polishing path planning method based on an evaluation function, and the method comprises the following steps: S1, analyzing the characteristics of a polishing path according to a path evaluation function, and searching the polishing path; s2, planning a spiral polishing path based on the path evaluation function; s3, according to the step S2, using different coefficients to obtain a series of different paths, and selecting an optimal polishing path; according to the spiral polishing path planning method provided by the invention, based on the path evaluation function, the optimal polishing path is planned and searched in an optimized search mode, some areas which do not need to be machined can be automatically avoided, the machining efficiency is improved, and the problem that in the prior art, in the machining process of using the spiral polishing path, the machining efficiency is poor is effectively solved. If a user wants to avoid a certain area, the advancing direction of
