摘　　要：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 3μm,and the surface roughness(Ra)is less than 2μm.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.
