Steel tower section machining quality control method based on space polygon

The invention relates to a machining quality control method based on a spatial polygon steel tower section. The machining quality control method is characterized by comprising the following specific control methods: S1, thermal deformation control; s2, supporting deformation is controlled; s3, cutting vibration control; s4, processing positioning and measurement basis determination; through uniform temperature control over a workshop, a steel tower section and machining equipment, the effect that the temperature of the workshop in the whole machining process is within a controllable temperature range is achieved, and the influence of thermal deformation on the machining precision is reduced; in addition, the supporting position of the steel tower section is adjusted through finite element analysis, and the influence of the dead weight of the steel tower section and the supporting force of a bottom beam on supporting deformation of the steel tower section is reduced; the end part of the steel tower section is
