Abstract

The machining accuracy of the curved surfaces of integrated turbine blades directly determines the performance and service life of the turbojet engine system. In this paper, a non-contact on-machine measurement system is developed for precision milling of integrated turbines to reduce the impact of workpiece deformation, overcutting, tool chatter, and material work hardening. Milling with the on-machine measurement system obtained high-quality integrated turbine surfaces. The geometric accuracy error (PV) is below 3 μm, and the surface roughness (Ra) is less than 2 μm. The processed integrated turbine blade can achieve the accuracy requirements in the design and manufacturing and can be practically applied to the entire turbojet engine.
