Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] In this embodiment, the steps of using the technical solution of the present invention to carry out micro-stress composite machining of the tenon and groove of the turbine disk are as follows:
[0023] Step 1. The wire cutting process in this processing method is completed by numerical control wire cutting equipment and molybdenum wire. According to the structure and size of the turbine disk 2, the clamping method of the turbine disk 2 is determined as follows: figure 1 , 2 As shown, the mounting seat 1 for installing the turbine disk blank 2 is connected to the turntable 6, and the wheel disk blank 2 is fixed by the pressing block 3 and the screw 4, and it is ensured that figure 2 The angle φ in is complementary to the included angle between the tenon groove of the turbine disk and the radial direction;
[0024] In the wire...
