The technique for guarantee of quality of the aircraft detail channels with the use of abrasive flow machining process

The main purpose of the research was the development of the technique for guarantee of the required accuracy of the components consumption through channels of aircraft details with a plenty of «hard-to-get» channels. The design engineering features of aircraft details are analyzed. The features of the abrasive flow machining process are considered. The technique for the required quality guarantee of the geometrically complex channels of aircraft details with the use of abrasive flow machining process is described. The approbation of this technique is performed with the use of the experimental plant. The recommendations for the choice of equipment, work medium composition and work parameters are offered. Use of the offered technique allows to carry out the finish machining operation of a channels of aircraft details with the given quality guarantee (accuracy of the components consumption through channels and pimples in a range Rа = 1,6... 3,2 microns) with the existing equipment.
