FIELD: machine engineering.
SUBSTANCE: geometric characteristics of the blade blank are measured, the measured shape is compared with the theoretical shape, areas of the blade blanks for polishing are determined, toolpath is formed and cutting modes are set. For polishing, a tool in the form of a polishing wheel is used, having conical, toroidal and the second conical cutting surfaces aligned thereon for processing the back and trough of the blade, the concave surface of the shelf interface and the shelf surface, respectively. Polishing of the mentioned areas of the blade blank is carried out by the corresponding cutting surfaces of the polishing wheel by means of two manipulators for relative movement of the blank and the circle.
EFFECT: final machining of all complex surfaces of the flowing part of the blade, taking into account the geometric characteristics of the blank.
