What is it about?

In work is considered a way of forecasting of axial displacement of a surface of a nonrigid disk during its processing due to modelling real conditions. Except for an opportunity of forecasting the given way allows to spend not destroying control of disks over propensity to deformations not only at its processing, but also during operation. Application of the presented way allows to lower quantity of technological losses by manufacture of nonrigid expensive disks of axial compressor

Why is it important?

By manufacture of thin-walled disks of axial compressor in diameter 500 – 1000 mm having a rim and a nave, from corrosion-proof materials characteristic and difficultly cleaned defect are loss of accuracy as a result deformation details. Deformation it is shown in axial displacement of a surface of a disk concerning its rim or a nave therefore the surface accepts the dome-shaped form with the arrow of the deflection exceeding sometimes the set error of manufacturing in 2 – 5 times. The study will help reduce the number of low-quality products.

Perspectives

It is possible to use the specified method of calculation on a stage of technological preparation of manufacture for calculation of an error of processing of disks. Thus, the opportunity of forecasting and elimination of the defects listed above kinds is the primary goal at designing technological processes of manufacturing of nonrigid disks and products similar to them. The most effective and significant is forecasting errors of processing by technological preparation of manufacture and at stages of development of manufacture of new products. Application of the presented way allows to lower quantity of technological losses by manufacture of nonrigid large-sized disks of the axial compressors.
