In particular, the invention relates to a method for manufacturing an annular wall for aircraft turbomachinery, which has a conical or trunnion shape around a longitudinal axis (a) and has a fixed annular flange at at least one longitudinal axis end, The wall is made of metal alloy and has at least one aerodynamic annular surface for airflow sweeping in turbomachinery operation. According to the invention, the wall and at least part of its flange are made into a whole by plastic deformation of the plate (30),This plastic deformation is achieved by at least one pebble (40) applied to a plate (30) supporting a spindle (50) rotating about the axis (a).Abstract figure: Figure 6
