Machining parameters can influence fatigue life by altering residual stresses, cold work and surface roughness. A study was performed to examine the effect of various broaching machining on high temperature lives a nickel-based disk alloy. The tool wear speed were studied their roughness quantified. These variables shown have substantial lives, failure mode type location. relationships between ...

Real-time monitoring in CNC machine tools is focused on the early detection of tool wear, and this way to assess part piece quality. The machining process known as broaching critical for firtree slots (dovetails) production turbomachinery components, such turbine disks. Tight tolerances one hand, even less than 5 µm firtree-slots pressure faces, high productivity other, are two main requirement...

Complex profile broaches are widely used in the manufacture of complex parts aero-engines, but forces broaching process difficult to predict and control. A new numerical model for force with tools was presented, which considered area arc length curved shear zone boundary. The were calculated by curve function boundary, is firstly predicted FEM simulation. Then, an experimental device set up car...
