Title:
流体工学的表面を適合表面として形成する方法
Document Type and Number:
Japanese Patent JP4486732
Kind Code:
B2
Abstract:
A method for producing matched surfaces on rotor units with integral blades comprising a hub and at least one blade ring, by removing by machine after integral joining with component overmeasure in the area of the joining zone, whereby at least one actual surface is acquired by measuring method, and a surface matching it, is produced. Acquisition by measuring method and production take place on a process machine in one clamping of the rotor unit. The desired surface of each processing area is provided in the form of stored data. Starting from at least one measured actual surface, a matched surface is produced beyond the joining zone, with the surface everywhere adjoining the actual surface and/or a so-called repair surface of which there is at least one, without any kinks or steps at a specifiable minimum curvature. As far as is possible, the surface itself corresponds to a mathematically continuous spatial surface comprising a locally and/or direction-dependent variably-specifiable minimum curvature, whereby approximation to the desired profile takes precedence over approximation to the desired position.
