METHOD OF PRODUCING ROTOR OR BLADED MACHINE, MACHINE TOOL FOR GRINDING AND DEVICE FOR AUTOMATIC CONTROL Russian patent published in 2002 - IPC

FIELD: gas-turbine engine, turbine-driven generator, and other bladed machines. SUBSTANCE: before producing rotor material is sorted for the tapping analysis and mechanical properties. Grinding with automatic control of the grinded profiles is finishing treatment. After that the workpiece is checked for dimensions and if they are correct the workpieces is strengthened. Lock and splined joints (external, internal, end face, Hirt's joints) are treated by laser beam in zones of stress concentrators. Grinding, control, strengthening ( or softening) by laser beam perform in one setting directly with machine tool. Machine tool is provided with device for automatic control of dimensions made of toroidal disk measuring tips mounted inside the housing with guidings for pair number of measuring carriages provided with contact surfaces and reading devices of linear displacements between measuring members with tips and stop tips interposed between contact surfaces of measuring carriages. EFFECT: improved method. 9 cl, 42 dwg
