There are many steps for machining complex parts on a machining center, and the operating sequence directly affects machining quality and machining efficiency. In this paper, through analysis of step sequencing rules and typical processes, an optimization model for sequencing machining steps on the machining center is established. Genetic algorithms are introduced into optimization of sequencing machining steps, and the application mechanism of the algorithms is discussed in detail. A new gene reordering operator is put forward. Finally an example is used to validate the algorithms.
