Method and device for machining the leading edge of a turbine engine blade |
摘要 |
A method and a device for machining the leading edge of a turbine engine blade by a machining center for which parameters are set is disclosed. The method includes: acquiring a 3D profile of the leading edge of the blade; calculating at least one characteristic of the leading edge from the 3D profile; comparing the value of the calculated characteristic with a known theoretical value of the characteristic to obtain an elementary difference for the characteristic; calculating at least one undulation of the leading edge between at least two consecutive elementary sections from the 3D profile; optimizing the elementary differences obtained as a function of the undulation; setting the parameters of the machining center as a function of the optimized elementary differences for the elementary sections to define machining passes over the leading edge; and machining the leading edge of the blade with the machining center with parameters set. |
