Machining process for a multi-vane nozzle

A method of machine finishing a blank casting of a multi-vane or bi-vane nozzle of turbine engine. The nozzle comprises a first vane 1 and a second vane 2 extending radially between inner ring sector 3 and inner ring sector 4 as shown in figure 1. A duct is defined between vanes 1 and 2 shown in fig...

Zusammenfassung:	A method of machine finishing a blank casting of a multi-vane or bi-vane nozzle of turbine engine. The nozzle comprises a first vane 1 and a second vane 2 extending radially between inner ring sector 3 and inner ring sector 4 as shown in figure 1. A duct is defined between vanes 1 and 2 shown in figure 1a. P12, P32 and P52 are points measure on the pressure face of vane 2 and P11,31 and P51 are points measured on the suction face of vane 1, opposite the measured points of vane 2. P7,P8,P9 and P10 are points measured on the inner and outer ring sectors. Using the measured points, a cross section of flow is calculated as well as machining allowances. The machining allowances are corrected according to the calculated cross section of flow.
