A method is proposed for predicting the flexure of disks for gas-turbine engines.

What is it about?

In the manufacture of titanium-alloy compressor disks and impellers for gas-turbine aircraft engines, it is impossible to produce thin-walled workpieces of complex shape by casting. Therefore, workpieces of simple form are produced, which entails the removal of large margins by machining. That increases the number of manufacturing operations. Each operation introduces stress in the surface layer of the machine part and redistributes the stress created in preceding operations.

Why is it important?

Many parts with thin-walled elements are used in the machine tool industry: disks, impellers, blades, rings, flanges, etc. These parts are difficult to manufacture on account of their low rigidity. That results in considerable losses, especially when a technology is first being introduced. To reduce the losses, less intense cutting conditions may be employed, but that also decreases the cutting forces. Correspondingly, the machining time is extended, and the productivity falls. These problems are especially notable in the aircraft industry. This solution will increase labor productivity.
