摘要： A fixture for use in the final machining operation of the integral bladed rotor (IBR) of a gas turbine engine comprises a rigid ring for surrounding the outer periphery of the IBR and supporting tapered pins that fit into the space between the blades and then molded therein with a plaster or plastic medium for securing the unit to the IBR for enhancing its structural integrity. The method of finishing the airfoils of the IBR includes inserting the pins in alternate spaces and working half of the blade surfaces in the pinless spaces and then removing the pins and inserting pins in the previously worked spaces and then molding the pins in place. The other half of the bladed surface is then worked in the pinless spaces until the airfoils are finally contoured. The unit is removed and heated to melt the residual cast medium to produce the finished product.
