The invention relates to a method for machining a seat leg frame of a helicopter operator seat to solve the problems of an existing seat leg frame machining method that machining difficulty is high, the requirement for the skill of operators is high, and machining efficiency is low. The method comprises the steps of machining the exterior outline of left seat legs and the exterior outline of right seat legs, connecting the left seat legs with the right seat legs fixedly and symmetrically to form a left seat leg and right seat leg assembly, machining all through holes in the left seat legs and right seat legs from one side of the left seat leg and right seat leg assembly at the same time, separating the machined left seat leg and right seat leg assembly, and fixing the left seat legs and the right seat legs with fixing rods to form the seat leg frame. According to the method, the left seat legs and the right seat legs are machined on a milling machine and a horizontal boring machine in a combined mode, positioning is reliable during machining, tool manufacturing is easy, operation is convenient, the qualified rate of machined parts is high, and production efficiency is improved.
